ABSTRACT
ABSTRACT Purpose: To evaluate the potential oncologic benefit of a visibly complete transurethral resection of a bladder tumor (TURBT) prior to neoadjuvant chemotherapy (NAC) and radical cystectomy (RC). Materials and Methods: We identified patients who received NAC and RC between 2011-2021. Records were reviewed to assess TURBT completeness. The primary outcome was pathologic downstaging (<ypT2N0), with complete pathologic response (ypT0N0) and survival as secondary endpoints. Logistic regression and Cox proportional hazards models were utilized. Results: We identified 153 patients, including 116 (76%) with a complete TURBT. Sixty-four (42%) achieved <ypT2N0 and 43 (28%) achieved ypT0N0. When comparing those with and without a complete TURBT, there was no significant difference in the proportion with <ypT2N0 (43% vs 38%, P=0.57) or ypT0N0 (28% vs 27%, P=0.87). After median follow-up of 3.6 years (IQR 1.5-5.1), 86 patients died, 37 died from bladder cancer, and 61 had recurrence. We did not observe a statistically significant association of complete TURBT with cancer-specific or recurrence-free survival (p≥0.20), although the hazard of death from any cause was significantly higher among those with incomplete TURBT even after adjusting for ECOG and pathologic T stage, HR 1.77 (95% CI 1.04-3.00, P=.034). Conclusions: A visibly complete TURBT was not associated with pathologic downstaging, cancer-specific or recurrence-free survival following NAC and RC. These data do not support the need for repeat TURBT to achieve a visibly complete resection if NAC and RC are planned.
ABSTRACT
ABSTRACT Purpose To evaluate the perioperative mortality and contributing variables among patients who underwent radical cystectomy (RC) for bladder cancer in recent decades, with comparison between modern (after 2010) and premodern (before 2010) eras. Materials and Methods Using our institutional review board-approved database, we reviewed the records of patients who underwent RC for primary urothelial bladder carcinoma with curative intent from January 2003 to December 2019. The primary and secondary outcomes were 90- and 30-day mortality. Univariate and multivariable logistic regression models were applied to assess the impact of perioperative variables on 90-day mortality. Results A total of 2047 patients with a mean±SD age of 69.6±10.6 years were included. The 30- and 90-day mortality rates were 1.3% and 4.9%, respectively, and consistent during the past two decades. Among 100 deaths within 90 days, 18 occurred during index hospitalization. Infectious, pulmonary, and cardiac complications were the leading mortality causes. Multivariable analysis showed that age (Odds Ratio: OR 1.05), Charlson comorbidity index ≥ 2 (OR 1.82), blood transfusion (OR 1.95), and pathological node disease (OR 2.85) were independently associated with 90-day mortality. Nevertheless, the surgical approach and enhanced recovery protocols had no significant effect on 90-day mortality. Conclusion The 90-day mortality for RC is approaching five percent, with infectious, pulmonary, and cardiac complications as the leading mortality causes. Older age, higher comorbidity, blood transfusion, and pathological lymph node involvement are independently associated with 90-day mortality.
ABSTRACT
ABSTRACT Objective: Robotic intracorporeal neobladder reconstruction is a complex procedure in which the approximation of the reservoir to the urethral stump can be a demanding step. The aim of the study is to evaluate the reproducibility of a modified posterior reconstruction (PR) during the reconfiguration of intracorporeal neobladder after robot assisted radical cystectomy (RARC). Materials and Methods: From July 2021 to July 2022, 35 RARC were performed, and 17 patients underwent intracorporeal neobladder reconstruction. A PR was planned in males (14). Intra- and peri-operative data were collected. Surgical technique: RARC and node dissection are performed. Afterwards, 40-cm ileal segment is isolated; the portion with the more adequate mesenteric length is brought down to the pelvis. A modified PR is performed with a double-armed barbed suture: a first layer connects the Denonvillier's fascia to the rhabdosphincter in a running fashion; the second layer is created with the other arm and approximates the posterior side of the ileal segment towards the urethral stump. In the anterior caudal part of the ileum, a 1.5-cm incision is made to realize the neobladder neck; the neovesical-urethral anastomosis is performed with a second bidirectional suture. Results: Anastomotic and PR time were 14 (range 7-20) and 5 minutes (4-8), respectively. A single Clavien IIIa complication was recorded in a patient who underwent NAC and had a C. albicans superinfection in the post-operative course. All patients were discharged with complete or acceptable bladder voiding. Twelve patients with follow-up >90-days reported a satisfying daytime continence. Conclusions: PR represents a simple technical refinement that improves neobladder-urethral anastomosis by favoring ileal approximation to the urethral stump and decreasing anastomotic tension.
ABSTRACT
Dandy-Walker syndrome is one of the posterior fossa malformations, which is easily confused with arachnoid cyst or cerebellar dysplasia in clinical practice, leading to misdiagnosis. Dandy-Walker syndrome is easy to be combined with hydrocephalus, resulting in increased intracranial pressure, increased head circumference, growth retardation, spastic hemiplegia and other manifestations, and can also be accompanied by other nervous system malformations. On February 27, 2021, a child with Dandy-Walker syndrome with growth retardation as the primary manifestation was admitted to Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine. After multiple surgical treatment, the child's hydrocephalus was significantly improved. Through the analysis of the clinical data of the child's operation and the treatment of complications, it is helpful to improve the clinicians' understanding of the surgical treatment of the disease.
ABSTRACT
Objective:To discusse the value of pituitin in laparoscopic ovarian cyst removal.Methods:From October 2015 to June 2018 in Dalian Medical University Affiliated Dalian Maternity Hospital, useing prospective research methods, 90 patients with unilateral ovarian cyst (except endometriomas) were randomly divided in 3 groups of pituitrin group,control group 1 and control group 2. The pituitrin group: laparoscopic cystectomy with the injection of diluted pituitrin 6 U, the total amount of diluted pituitrin 10 - 20 ml, ovarian hemostasis was achieved by sutura. The control group 1: ordinary laparoscopic cystectomy without injection suture hemostasis. The control group 2: laparoscopic cystectomy with the injection of normal saline 10 - 20 ml, ovarian hemostasis was same to pituitrin group. The operation time and the amount of bleeding were compared among the three groups. The ovarian reserve was compared between before and 3 months after operation by estradiol (E 2), follicle-stimulating hormone (FSH), luteinizing hormone (LH). Results:The amount of bleeding in the pituitrin group was less than that in the control group1: (14.00 ± 5.48) ml vs. (18.33 ± 6.99) ml, P<0.05. The operation time in the pituitrin group and control group 2 was less than that in the control group1: (43.50 ± 7.21) min, (45.00 ± 10.29) min vs. (50.17 ± 8.95) min, P<0.05. The level of FSH after operatiaon in the pituitrin group and control group 2 was less than that in the control group1: (7.20 ± 1.55) U/L, (7.43 ± 1.52) U/L vs. (8.31 ± 0.97) U/L, P<0.05. The level of E 2 3 months after operation in the pituitrin group was higher than that in the control group 1 and control group 2: (54.20 ± 10.90) ng/L vs. (46.63 ± 10.76) ng/L, (43.90 ± 18.23) ng/L, P<0.05. There was no significant difference of LH 3 months after operation among the three groups ( P>0.05). Conclusions:This study shows that diluted pituitrin decreases operation time and the amount of bleeding during operation, at the same time,the pituitrin injection is valued of ovarian reserve.
ABSTRACT
【Objective】 To analyze the risk factors of ileus after radical cystectomy, and to construct a nomogram predictive model accordingly. 【Methods】 Clinical data of patients who underwent radical cystectomy during Jan.2018 and Dec.2021 were collected. The risk factors related to postoperative ileus were assessed with Logistic univariate and multivariate regression analysis. After that, the predictive model was constructed and its specificity and accuracy were verified. 【Results】 A total of 326 patients were included, 65 of whom developed ileus. Statistical analysis showed that gender, lymph node dissection, serum creatinine and albumin were correlated with postoperative ileus. The area under the receiver operating characteristic curve of the model was 0.769 (95%CI:0.724-0.802). Bootstrap correction curve showed that the model had good prediction accuracy. 【Conclusion】 Male, lymph node dissection, elevated postoperative serum creatinine and postoperative blood albumin decrease are predictors of ileus. The nomogram predictive model based on these predictors can predict the probability of ileus after radical cystectomy.
ABSTRACT
【Objective】 To investigate the predictive value of high preoperative neutrophile-lymphocyte ratio (NLR) for the prognosis of nonurothelial carcinoma of the bladder (NUBC) after radical cystectomy (RC). 【Methods】 Clinical and follow-up data of NUBC patients undergoing RC during Jan.2005 and Dec.2020 were collected. The optimal cut-off value of NLR was determined with the receiver operating characteristic (ROC) curve. The survival curve was drawn with Kaplan-Meier method to compare the differences in cancer specific survival (CSS) and overall survival (OS) between the high-NLR and low-NLR groups. The independent risk factors of CSS and OS were screened with Cox proportional hazard regression model. 【Results】 Of the 62 eligible cases,34 (54.8%) were diagnosed with adenocarcinoma,17 (27.4%) with squamous cell carcinoma, 6 (9.7%) with small cell carcinoma and 5 (8.1%) with sarcoma. Kaplan-Meier analysis results showed high NLR was associated with poor CSS (P=0.001) and OS (P<0.001). Cox regression results indicated that high NLR (HR=2.42, 95%CI: 1.12-5.23, P=0.025) and advanced pathologic tumor stage (HR=3.21, 95%CI:1.53-6.74,P=0.002) were independent risk factors of unfavorable CSS. Similarly, high NLR (HR=2.75, 95%CI: 1.35-5.56, P=0.005) and advanced pathologic tumor stage (HR=2.81, 95%CI:1.43-5.57, P=0.003) were independent risk factors of unfavorable OS. 【Conclusion】 As an independent risk factor of unfavorable CSS and OS in NUBC patients undergoing RC, high preoperative NLR is of great value in the prediction of long-term prognosis and may help to optimize individualized treatment.
ABSTRACT
The urethrovesical anastomosis during total laparoscopic radical bladder cancer was mostly operated by one-hand. In this study, 10 patients with bladder cancer were legally operated by double-hand, all of which were successfully completed. With the follow-up of 3-15 months, the patient could urinate smoothly, with no anastomotic fistula or stenosis. The effect of the urethrovesical anastomosis was satisfactory.
ABSTRACT
Objective:To explore the effect of enhanced recovery after surgery (ERAS) protocols in patients undergoing laparoscopic radical cystectomy (LRC) and intracorporeal urinary diversion (ICUD).Methods:A total of 83 patients who received LRC+ ICUD in Beijing Chaoyang Hospital from March 2014 to September 2020, were divided into 2 groups based on different perioperative management, including 29 ERAS cases and 54 conventional recovery after surgery (CRAS) cases. The ERAS group included 26 males and 3 females , with an average age of (62.07 ± 9.26) years. There were 26 patients with ASA class Ⅰ-Ⅱ, 3 patients with ASA class Ⅲ, 4 patients received neoadjuvant chemotherapy, and 7 patients had a history of abdominal surgery in ERAS group. The CRAS group included 44 males and 10 females , with an average age of (61.59 ± 10.16) years. There were 50 patients with ASA class Ⅰ-Ⅱ, 4 patients with ASA class Ⅲ, 9 patients received neoadjuvant chemotherapy, and 10 patients had a history of abdominal surgery in CRAS group. There were no statistically significant differences in the baseline characteristics between the two groups. The patients in both groups underwent LRC+ ICUD procedures. The perioperative results and complications between the two groups were compared.Results:In the ERAS group, there were 20 patients who underwent Bricker ileal conduit surgery and 9 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 3, 3, 7, 7, 5 and 4 cases in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 23, 2, 3 and 1 patient with pathological stage N 0, N 1, N 2 and N 3, respectively. Pathological diagnosis included 3 cases of low-grade urothelial carcinoma, 24 cases of high-grade urothelial carcinoma, and 2 cases of other histological subtypes. In the CRAS group, there were 31 patients who underwent Bricker ileal conduit surgery and 23 patients who underwent Studer orthotopic ileal neobladder surgery. Pathological staging included 5, 3, 12, 9, 15 and 10 patients in stage T a, T is, T 1, T 2, T 3 and T 4a, respectively. There were 35, 6, 7 and 6 patients with pathological stage N 0, N 1, N 2, and N 3, respectively. Pathological diagnoses included 6 cases of low-grade urothelial carcinoma, 45 cases of high-grade urothelial carcinoma, and 3 cases of other histological subtypes. There were no statistically significant differences ( P>0.05) in surgical methods, pathological staging, or pathological types between the ERAS and CRAS groups. ERAS group presented less albumin loss [(25.73±8.63)% vs. (32.63±9.05)%, P=0.001], shorter hospital stay [9(7, 13)d vs. 12(9, 16)d, P=0.006], less 30-day overall complications [55.2% (16/29) vs. 83.3% (45/54), P=0.009]. In multivariable analysis, maximum albumin loss≥20% was independently associated with 30-day minor complications ( P=0.049), and maximum albumin loss ≥25% was independently associated with hospital of stay≥10 days ( P=0.038), respectively. Conclusions:For patients who received LRC+ ICUD, ERAS was associated with reduced perioperative albumin loss, shorter length of stay, less 30-day complications, accelerated recovery time, improved clinical outcome and less albumin injection.
ABSTRACT
Objective:To discuss the classification and treatment of ureteroileal anastomotic stricture (UAS) after radical cystectomy.Methods:The clinical data of 34 patients with UAS after radical cystectomy in the Department of Urology of Tongji Hospital from January 2017 to January 2022 were reviewed and analyzed. There were 25 males and 9 females. The average age was (66.3±7.7)years, including 2 cases of bilateral hydronephrosis and 32 cases of unilateral hydronephrosis. The average time of UAS was detected (14.7±6.5)months after radical cystectomy. There were 32 patients of unilateral hydronephrosis and 2 patients of bilateral hydronephrosis. Two patients had undergone nephrostomy in an external hospital. Three patients had elevated leukocytes in blood routine. Among them, two patients had fever. First, nephrostomy on the hydronephrosis side and anti-infection treatment were performed. After routine blood tests showed that the white blood cells were normal and antibiotics were stopped for 24 hours without fever, the operation was performed. 34 patients had preoperative hydronephrosis of (2.7±0.6) cm. Of the 34 cases in this group, 5 cases were injected with methylene blue through a preoperative nephrostomy tube, and 29 were injected with methylene blue through the renal pelvis using an 18G puncture needle under ultrasound guidance. Using a ureteroscope to observe in the ileal bladder, methylene blue was seen in 4 cases. Methylene blue was used to guide the search for the stenosis and a super smooth guide wire was inserted. Among them, 3 cases were dilated with a 5 mm ureteral dilation balloon catheter, 1 case was dilated with a F14 ureteral access sheath, and then a F6 single J stent was inserted. Methylene blue was not seen in the ileal conduit in 30 cases, of which 16 cases were treated with a flexible ureteroscope through the nephrostomy to locate the stenosis, incised with a 30 W holmium laser. 9 cases were treated with 5 mm ureteral dilation balloon catheter, and 7 cases were treated with a F14 ureteral access sheath, and then an F6 single J stent was inserted. 14 cases were unable to find the stenosis by antegrade method. According to the operation time and patient's condition, it was decided to perform immediate or second stage dual endoscope surgery. Through the nephrostomy, a flexible ureteroscope was used to enter the stenosis along the super slide guide wire. A rigid ureteroscope was used to observe the stenosis through the ileal conduit, and the stenosis was found. The stenosis was found in 10 cases and incised with a 30 W holmium laser. 8 cases were treated with 5 mm ureteral dilation balloon catheter, and 2 cases were treated with a F14 ureteral access sheath, and then an F6 single J stent was inserted. 4 cases were still unable to accurately locate the stenosis using the dual endoscope surgery(one case was bilateral stenosis, and one side was relieved), and continued indwelling nephrostomy. The definition of successful removal of stricture in this study is that an F6 single J stent can be inserted into the ureter.Results:UAS were classified into four types based on the severity of the intraoperative findings: Type Ⅰ, the narrow ureteral lumen is more than 50% narrower than the normal ureteral lumen, but methylene blue can pass through in strands; Type Ⅱ, needle like stricture of the ureteral lumen, allowing only methylene blue filaments to pass through; Type Ⅲ, membranous atresia of the ureter, with a narrow segment of 1 to 3 mm in length, and methylene blue cannot pass through; Type Ⅳ, long segment stenosis. Of the 34 cases in this group, 4 cases were type Ⅰ, and the stenosis was dredged by retrograde method; 16 cases were type Ⅱ, and the stenotic segments were dredged by antegrade method; 10 cases were type Ⅲ, and the stenosis was dredged by the dual endoscope surgery; Four cases were of type Ⅳ (one case was of bilateral UAS, one side was of type Ⅲ, and the other side was of type Ⅳ, which was classified as type Ⅳ). The stenotic segment could not be solved through the above methods. Among the 34 patients, 30 patients were successfully relieved of anastomotic obstruction, and 1 patient with bilateral obstruction was unilaterally relieved of anastomotic obstruction. In the other 3 cases, because the stenosis segment was too long, 2 cases were changed to nephrostomy, and 1 case was changed to open surgery, with a success rate of 88.2%. UAS was classified into 4 types based on the severity of UAS seen during surgery. No serious complications occurred during and after the operation. During the follow-up of 6-24 months, the imaging evaluation of 4 patients showed that hydronephrosis was aggravated, with an average increase in creatinine of (32.5±10.9)μmol/L, requiring replacement of a single J tube. The imaging evaluation of the remaining 26 patients showed that the postoperative hydronephrosis was 0.9 ± 0.6 cm less than the preoperative hydronephrosis 2.6 ± 0.6 cm, with a statistically significant difference ( P<0.01). The quality of life score at 3 months after surgery was (1.9±0.6), which was significantly improved compared to the preoperative indwelling nephrostomy period (5.2±0.7), with a statistically significant difference ( P<0.01) Conclusions:The treatment of UAS after radical cystectomy with retrograde, antegrade, and dual endoscope surgery has a high success rate, which can help some patients avoid the inconvenience of indwelling external drainage tubes and the risk of open surgery. Choosing an appropriate surgical method can achieve the goal of treating UAS with minimal trauma.
ABSTRACT
Objective:To determine the impact of body mass index (BMI) on perioperative and oncological outcomes after robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion.Methods:Clinical data of bladder cancer patients undergoing robot-assisted radical cystectomy with intracorporeal urinary diversion in Zhejiang Provincial People's Hospital from January 2017 to January 2020 were retrospectively analyzed. Patients were divided into three groups according to BMI, including 61 cases in normal group (<25.0 kg/m2), 52 cases in overweight group (25.0-29.9 kg/m2) and 33 cases in obese group (≥30.0 kg/m2). In the normal group, the median age was 73.6(59, 79), including 45 male(73.8%), with 51 cases(83.6%) of ASA score 0-2, 10 cases (16.4%)of 3 or higher, and 10 cases (16.4%) undergoing neoadjuvant chemotherapy. Past medical history included smoking in 34 cases (55.7%), hypertension in 19 cases (31.1%), diabetes in 10 cases (16.4%), heart disease in 12 cases (19.7%), and abdominal surgery in 6 cases (9.8%). In the overweight group, the median age was 69.7(60, 78), including 38 male (73.1%), with 25 cases (48.1%)of ASA score 0-2, 27 cases (51.9%) of 3 or higher, and 9 cases (17.3%) undergoing received neoadjuvant chemotherapy. Past medical history included smoking in 30 cases (57.7%), hypertension in 20 cases (38.5%), diabetes in 10 cases (19.2%), heart disease in 9 cases (17.3%), and abdominal surgery in 5 cases (9.6%). In the obses group, the median age was 69.9(61, 78), including 21 male(63.7%), with 20 cases (60.6%)of ASA score 0-2, 13 cases(39.4%) of 3 or higher, 9 cases (27.3%) undergoing neoadjuvant chemotherapy. Past medical history included smoking in 18 cases (54.5%), hypertension in 17 cases (51.5%), diabetes in 19 cases (57.6%), heart disease in 7 cases (21.2%), and abdominal surgery in 4 cases (12.1%). After statistical comparison among the three groups, it was found that the proportion of patients with hypertension and diabetes in the obesity group and overweight group was higher than that in the normal group (all P<0.05), but there was no significant difference in other factors (all P>0.05). During the surgical process, robot-assisted radical cystectomy and bilateral pelvic lymph node dissection were performed firstly. The scope of lymph node dissection was divided into standard range and expanded range, and the diversion was divided into orthotopic neobladder and ileal bladder. During the orthotopic neobladder process, 40-50 cm ileum at the distance of 15 cm away from ileocecum was obtained by stapler, and then the U-shaped neobladder was made, and the new bladder was anastomosed with urethra and bilateral ureter. For ileal bladder, the ileum was cut off 15cm away from the ileocecum with stapler to obtain the 15 cm ileum to prepare the ileal conduit and restore the continuity of the ileum. The bilateral ureteral spacing 3cm was implanted on the ileal conduit. In the normal group, standard range lymphatic dissection was performed in 20 cases (32.8%), enlarged dissection in 41 cases (67.2%), orthotopic neobladder in 22 cases(36.1%), and ileal conduit in 39 cases (63.9%). In the overweight group, standard range lymphatic dissection was performed in 12 cases (23.1%), enlarged dissection in 40 cases (76.9%), orthotopic neobladder in 26 cases (49.1%), and ileal conduit in 26 cases (50.9%). In the obesity group, the standard range of lymphatic dissection was performed in 7 cases (21.2%), enlarged dissection in 26 cases (78.7%), orthotopic neobladder in 7 cases (21.2%), and ileal conduit in 26 cases (78.8%). There was no significant difference among the three groups (all P>0.05). Compared the operation time, intraoperative blood loss, postoperative exhaust time, postoperative time of taking solid food, postoperative hospital stay, postoperative complications (according to the Clavien-Dindo grading system, postoperative complications are reported inⅠ-Ⅱ grade as mild complications and above Ⅲ grade as serious complications) and pathology results in three groups. Results:All cases successfully underwent robotically without conversion or major intraoperative complications. The operation time in overweight and obsess group were longer than that of normal group with RARC or orthotopic neobladder [310(250, 350) min, 370(310, 420) min, 250(230, 310) min, ( P<0.05)], but there was no significant difference in RARC and ileal conduit[270(220, 300) min, 280(230, 300) min, 240(220, 290)min, P>0.05]. The estimated blood loss in overweight and obsess group was more than that in normal group [230(150, 450)ml, 310(250, 600)ml, 190(100, 350)ml, P<0.05], but there was no difference in blood transfusion rate [4(7.7%), 2(6.1%), 5(8.2%), P>0.05]. The exhaust time [2(1, 3) days, 2(1, 4)days, 2(1, 4)days], postoperative solid food intake time [4(3, 5)days, 4(3, 6)days, 4(3, 6)days] and the hospital stay[10(5, 16)days, 10(6, 17)days, 12(6, 20)days] were not different in three groups(all P>0.05). The mild complication rates in 90 days were significant higher in overweight and obsess groups[28 (53.8%), 16(48.5%), 20(32.8%), P<0.05], but the total and severe complication rates were not significantly different. The incidences of urinary system complications and incision complications in obese and overweight patients were significantly higher than those in normal group ( P<0.05). There was no significant difference in the incidence of gastrointestinal complications and ureteral anastomosis-related complications (stricture or urinary leakage)( P>0.05). There was no significant difference in the number of dissected lymph node, positive lymph node, positive rate of incisional margin and postoperative pathological stage among three different BMI groups(all P>0.05). Conclusion:Robot-assisted radical cystectomy combined with intracorporeal urinary diversion is a safe and effective method for the treatment of overweight, obese and even morbidly obese patients with bladder cancer. The recovery of intestinal function and the oncological results are not affected by body mass index. However, laparoscopic radical cystectomy for overweight and obese patients, especially for orthotopic neobladder, has the risk of long operation time, large amount of intraoperative bleeding and increased risk of minor postoperative complications.
ABSTRACT
Objective:To summarize the efficacy and safety of transurethral partial cystectomy combined with intravesical suturation in the treatment of bladder cancer.Methods:The clinical data of 28 patients with bladder cancer who were admitted in Zhengzhou People's Hospital from July 2020 to October 2021 were analyzed retrospectively. There were 22 males and 6 females, with the average age of (68.8±8.9) years old. Twenty cases were with single bladder tumor, and 8 cases were with multiple bladder tumors. The diameter of single bladder tumor measured by CT was less than 4 cm, with a median tumor diameter of 2.3(0.9, 2.8)cm. All 28 patients underwent transurethral partial cystectomy combined with intravesical suturation for the first time. Intraoperative intravesical instillation was conducted with 1 g gemcitabine. Bladder hot reperfusion treatment was performed with gemcitabine 2 g at 45℃ immediately after operation. The patients underwent reexamination with cystoscopy every 3 months after operation.Results:All the 28 patients successfully completed the operation. The average operation time was (128.3±16.3)min. No obturator nerve reflection was induced during operation. Muscularis tissue was found in all tumor pathological specimens after operation, among which 4 cases showed muscularis infiltration. Pathology of tumor basal and peripheral tissues showed tumor cell infiltration in 3 cases (1 case full-thickness infiltration, namely the incision margin was positive). The median continuous irrigation time of bladder after operation was 24.0(20.9, 25.0)h. The median time of indwelling catheter after operation was 6.5(6.0, 7.0)days, and one case developed severe bladder spasm. All patients were followed up, with a median follow-up of 7.5(4.0, 10.8) months.Postoperative recurrence occurred in 3 cases, all of which were ectopic recurrence in bladder.The 1-year recurrence rate was 10.7% (3/28).Conclusions:In the first surgical treatment of bladder cancer, transurethral partial cystectomy combined with intravesical suturation can provide accurate pathological staging, and low positive surgical margin rate. Immediate suturation of bladder wound during operation and immediate bladder perfusion chemotherapy can provide short bladder irrigation time, with few adverse reactions and low incidence of complications.
ABSTRACT
Objective:To compare the complications associated with various urinary flow diversion methods and identify the factors that contribute to the decline in renal function after radical total cystectomy for myoinfiltrating urothelial carcinoma.Methods:This study conducted a retrospective analysis on the clinical data of 46 patients with pathologically confirmed muscle-invasive bladder cancer.The patients underwent laparoscopic radical cystectomy with either ileal conduit diversion(n=21)or ureterocutaneous diversion(n=25)between January 2017 and December 2021.Perioperative data, postoperative pathology, postoperative complications, and follow-up results were compared between the two groups.Results:The study found significant differences between the two groups in terms of age[(67±6)years vs.(73±8)years, t=3.132, P=0.003], Charlson comorbidity index adjusted for age[(3.80±1.15) vs.(4.52±1.03), t=2.223, P=0.031], prognostic nutritional index[(48.81±5.74) vs.(43.64±4.74), t=3.347, P=0.002], operation time[(449±108)minutes vs.(326±130)minutes, P=0.001]], hospital stay[(20.1±11.1)days vs.(13.3±5.2)days, t=2.762, P=0.008], proportion of Clavien grade 3 or higher complications within 3 months after surgery(4/21 vs 0/25, χ2=2.105, P<0.05), and proportion of stoma-free patients(18/21 vs.5/25, χ2=6.373, P<0.01). According to Logistic multivariate analysis, perioperative blood transfusion and urinary tract infection were identified as independent risk factors for renal function decline 12 months after surgery.Escherichia coli was found to be the most common bacteria cultured from urinary tract infections in both groups after surgery. Conclusions:Laparoscopic radical cystectomy with ureterocutaneous diversion offers benefits such as shorter hospital stays and fewer perioperative complications for older and frail patients.However, a higher proportion of patients may require ureteral stenting.It is important to note that perioperative blood transfusion and urinary tract infection are major risk factors for renal function decline following radical cystectomy.
ABSTRACT
Objective:To study the effect of different hemostasis methods on postoperative pain and sex hormone levels in patients undergoing laparoscopic ovarian cystectomy.Methods:A total of 118 patients with ovarian cysts admitted to our hospital from Jun. 2018.6 to Aug. 2020 were collected and grouped by digital table method into electrocoagulation hemostasis group (59 cases, electrocoagulation hemostasis) and suture hemostasis group (59 cases, suture hemostasis). Pain at time points, serum inflammatory factors and sex hormone levels in the two groups were measured, and the incidence of complications was counted 12 weeks after surgery.Results:The VAS scores of suture hemostasis group at 6, 12 and 24 h after operation (3.33±0.93, 3.63±1.02, 3.01±0.94) were significantly lower than those of the electrocoagulation hemostasis group (4.16±1.05, 4.61±1.17, 3.72±1.05) ; there was no significant difference in serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels between the preoperative suture hemostasis group and the electrocoagulation hemostasis group. The serum levels of IL-6 and TNF-α in the group (37.64±4.82ng/L, 39.67±4.71ng/L) were lower than those in the electrocoagulation hemostasis group (45.96±5.25ng/L, 48.96±5.14ng/L) ( P<0.05) .) ; there was no significant difference in serum follicle-stimulating hormone (FSH), estradiol (E 2) or luteinizing hormone (LH) levels between preoperative electrocoagulation hemostasis group and suture hemostasis group ( P>0.05) ; There was no significant difference in the three indexes in the suture hemostasis group 3 months after operation compared with those before treatment ( P>0.05). The serum FSH and LH [ (6.59±0.91) mIU/ml, (5.24±0.77) mIU/ml] in the suture hemostasis group were lower than those in the electrocoagulation hemostasis group [ (7.39±1.02) mIU/m, (5.97±0.89) mIU/m], E 2 in suture hemostasis group [ (51.08±6.09) pg/ml] was higher than that in electrocoagulation hemostasis group [ (46.88±5.59) pg/ml] ( P<0.05). In terms of the complication rate at 3 months after operation, the suture hemostasis group (32.20%) was significantly lower than electrocoagulation hemostasis (13.56%) ( P<0.05). After 1 year of follow-up, the pregnancy success rate of the suture hemostasis group (72.88%) was significantly higher than that of the electrocoagulation hemostasis group (52.54%) ( P<0.05). There was no significant difference in pregnancy outcomes ( P>0.05) . Conclusions:Suture hemostasis in patients undergoing laparoscopic ovarian cystectomy is beneficial to relieve postoperative pain, improve postoperative inflammatory response, protect their ovarian function, avoid complications such as abnormal ovulation and excessive menstrual flow, and improve the success rate of pregnancy. The overall application effect is better than electrocoagulation hemostasis.
ABSTRACT
Objective:To investigate the influencing factors of survival benefit of patients after radical cystectomy and its correlation with preoperative albumin-to-alkaline phosphatase ratio (AAPR).Methods:The clinical data of 116 patients after radical cystectomy were retrospectively analyzed from January 2011 to January 2020 in Handan First Hospital. The influencing factors of survival benefit of patients after radical cystectomy were analyzed and the correlation between preoperative AAPR and overall survival time were evaluated. Kaplan-Meier method was used for survival analysis, and Log-rank test was used for comparison between groups. Cox proportional regression model was used to analyze the influencing factors of survival and prognosis and the correlation with preoperative AAPR. Trend Chi-square test was used to evaluate the level of preoperative AAPR.Results:Univariate Cox regression analysis showed that age, tumor diameter, pT stage, pN stage, histopathological grade, hydronephrosis, postoperative adjuvant chemotherapy and preoperative AAPR level were related to the overall survival time of patients after radical cystectomy( P<0.05). Multivariate Cox regression analysis showed that in calibration model Ⅰ and Ⅱ, the risk of death in high AAPR group was 0.351 and 0.433 times higher than low AAPR group( P<0.05). The risk of death decreased to 85.9% and 84.6% for every one unit increase of preoperative AAPR. The overall survival time of patients with high AARP level were significantly longer than patients with low and medium AARP level( P<0.05). Conclusion:The survival benefit of patients after radical cystectomy was independently related to the preoperative AAPR level; the higher the preoperative AAPR level, the longer the overall survival time.
ABSTRACT
SUMMARY OBJECTIVE: Wound dehiscence is associated with high morbidity and mortality. This study aimed to analyze the risk factors and comorbidities in the patients undergoing radical cystectomy with early postoperative wound dehiscence. METHODS: In all, 539 patients with bladder cancer who underwent radical cystectomy and urinary diversion at a single center between January 2008 and January 2022 were included in the study. The data related to the demographics, medical history, and perioperative clinical features were reviewed. Univariate and multivariate regression analysis was performed to identify risk factors for wound dehiscence. RESULTS: The mean age of the patients was 64.2 years (22-91). The mean body mass index was 26.4 kg/m2 (18.7-35.4). Wound dehiscence was observed in 43 (7.9%) of 539 patients. The patients with wound dehiscence had significantly higher mean BMI (27.8 vs. 26.3, p=0.006), ASA scores (p=0.002), history of chronic obstructive pulmonary disease (30.2 vs. 14.3%, p=0.006), diabetes mellitus (44.2 vs. 17.9%, p=0.003), previous abdominal surgery (18.6 vs. 7.7%, p=0.014), and postoperative ileus (58.1 vs. 16.9%, p=0.006). In the multivariable regression model, diabetes mellitus (odds ratio [OR] 4.9, 95%CI 2.3-10.1; p<0.001), postoperative ileus (OR 8.1, 95%CI 4.1-16.5; p<0.001), and chronic obstructive pulmonary disease (OR 2.6, 95%CI 1.2-5.7; p=0.013) were independent predictors of abdominal wound dehiscence following radical cystectomy. CONCLUSION: Diabetes mellitus, chronic obstructive pulmonary disease, and postoperative ileus were strongly associated with abdominal wound dehiscence following radical cystectomy. Both potential preventive and therapeutic interventions may decrease the risk of wound dehiscence.
ABSTRACT
Background:Laparoscopy is a widely used procedure in gynecological cases both for diagnostic and operative procedures. It is recommended due to lesser hospital stay, less post operative pain and better panoramic vision. Aim of the study is to assess the effectiveness of laparoscopic intervention of adnexal masses with benign pathology in recent series of consecutive patient. The focus is on pathology findings, length of stay, operating time, complications and laparotomy conversion rate. Material And Methods: This was a prospective observational study conducted at tertiary care hospital in Department of Obstetrics & Gynaecology during period of 1stAugust 2018 to 31st July 2020.This study consists of 70 patients, who presented with symptoms like pain in abdomen, bleeding per vaginum, irregular menses, excessive white discharge, distension of abdomen, infertility visiting outdoor patient department either diagnosed clinically(sign and symptoms) or by ultrasonography of adnexal masses. Result:Maximumpatients in this study were in age group 21-30 years. Maximum patients(21.42%)were having simple cyst. Among laparoscopic procedure most common procedure was left ovarian cystectomy(38.57%). Mean operative duration was 40.78 min and average duration of hospital stay was 3 days. There were minimal peri-operative complications; commonest being postoperative fever. Conclusion:Ade quatesurgical skill, case selection, multi disciplinary team approach and expert laproscopic surgical team are imperative for good patient outcome. This study gives an overview of experience in favour of laproscopic management of benign adnexal mass
ABSTRACT
Hydatid disease is a zoonotic parasitic disease most frequently caused by echinococcus granulose Primary peritoneal hydatidosisis very rare. We report a case of primary hydatid disease of the intraperitoneal pelvic space.A 22-year-old male patient presented with a history of abdominal pain since 5 months. Abdominal examination revealed a smooth, firm, mildly tender, non-mobile lump in suprapubic region, on digital rectal examination, a smooth spherical mass was felt anteriorly and laterally outside the rectal wall, rectal mucosa was normal. All routine investigations including liver function tests were within normal limits Computed tomography scan of the whole abdomen showed giant cyst of 10� cm with multiple well-defined cysts in rectovesical pouch.Diagnostic laparoscopy was performed. The liver, spleen, mesentery, omentum was found to be normal. A large tense hydatid cyst was noted in the pelvic cavity.Partial peri-cystectomy with endo-cystectomy was performed. Postoperative period was uneventful and patient was discharged on 4th postoperative day.Primary intra-abdominal but extra-peritoneal localization has been reported in only 0.2-2% cases making it a very rare entity.The treatment of choice for pelvic hydatid cyst is principally a careful surgical excision. Here with minimum invasive technique this case was operated and results were excellent
ABSTRACT
ABSTRACT Purpose: A systematic review of the literature with available published literature to compare ileal conduit (IC) and cutaneous ureterostomy (CU) urinary diversions (UD) in terms of perioperative, functional, and oncological outcomes of high-risk elderly patients treated with radical cystectomy (RC). Protocol Registration: PROSPERO ID CRD42020168851. Materials and Methods: A systematic review, according to the PRISMA Statement, was performed. Search through the Medline, Embase, Scopus, Scielo, Lilacs, and Cochrane Database until July 2020. Results: The literature search yielded 2,883 citations and were selected eight studies, including 1096 patients. A total of 707 patients underwent IC and 389 CU. Surgical procedures and outcomes, complications, mortality, and quality of life were analyzed. Conclusions: CU seems to be a safe alternative for the elderly and more frail patients. It is associated with faster surgery, less blood loss, lower transfusion rates, a lower necessity of intensive care, and shorter hospital stay. According to most studies, complications are less frequent after CU, even though mortality rates are similar. Studies with long-term follow up are awaited.

The incidence of inflammatory myofibroblastic sarcoma is low, and bladder origin is more rare. We reported a 58-year-old patient with painless gross hematuria for one week. Total abdominal CT examination showed soft tissue mass in the anterior wall of the bladder, which was considered as bladder cancer, and bladder tumor resection was performed. Postoperative pathology showed inflammatory myofibroblastic sarcoma. Therefore, radical cystectomy was performed because of the high degree of malignancy. There was no recurrence during 3 years follow-up.
