ABSTRACT

Objective To investigate clinical characteristics and risk factors of different stages of urinary tract infection after kidney transplantation. Methods Clinical data of 209 kidney transplant recipients were retrospectively analyzed. According to time points of postoperative follow-up, all recipients were divided into 3 stages: within 1 month post-kidney transplantation, 1-6 months post-kidney transplantation, and 7-12 months post-kidney transplantation. The incidence of urinary tract infection, urine culture results of recipients with urinary tract infection and drug resistance characteristics of common pathogens during different stages after kidney transplantation were analyzed. The strains of patients with recurrent urinary tract infection were identified. The risk factors of urinary tract infection and the effect of urinary tract infection on renal allograft function were analyzed. Results The urinary tract infection rate was 90.0% in the first stage, 49.3% in the second stage and 22.5% in the third stage. The urinary tract infection rates of male recipients undergoing living-related organ donation in the second and third stages were lower than those of female recipients (both P<0.05). Urine culture test yielded positive results in 60 cases, and 84 strains of pathogenic bacteria were detected, mainly Gram-negative bacteria, among which Klebsiella pneumoniae accounted for the highest proportion. Sixty-six recipients had recurrent urinary tract infection, and the detected pathogens included Klebsiella pneumoniae, Escherichia coli and Candida glabrata, etc. Univariate analysis showed that postoperative use of antithymocyte globulin was the risk factor for urinary tract infection in the first stage. Preoperative urinary tract infection and donor type were the risk factors for urinary tract infection in the second stage. Gender and age of the recipients were the risk factors for urinary tract infection in the third stage. Multivariate analysis revealed that postoperative use of antithymocyte globulin was the risk factor for urinary tract infection in the first stage. Gender and age of the recipients were the risk factors for urinary tract infection in the third stage (all P<0.05). In the third stage, 65 cases were cured and 38 cases were not cured. In the treated recipients, the serum creatinine level and white blood cell count were decreased after corresponding treatment than those before treatment (both P<0.05). Conclusions Gram-negative bacteria are the main pathogens of urinary tract infection in kidney transplant recipients, and drug resistance is relatively high. Postoperative use of antithymocyte globulin, female and old age are the risk factors for urinary tract infection in kidney transplant recipients.

ABSTRACT

【Objective】 To reduce the incidence of postoperative intestinal obstruction, we tried to improve surgical techniques by closing the cavity formed during radical cystectomy + ileal passage (Bricker) via laparoscopy to prevent the formation of abdominal hernia. 【Methods】 During Oct.2018 and Feb.2022, 41 patients were involved (conventional group). After standard laparoscopic radical cystectomy + pelvic lymphadenectomy, the ileum channel was established. The right medial retroperitoneum was sutured to cover the mesothelium and end of the ileum channel under open operation or endoscope. The space between the ureter and mesothelium of the ileum channel was sealed, and the end of the ileum channel and both ureters were externalized. During Feb.2022 and Dec.2022, 15 patients were involved (modified group). The right inner and outer lateral peritoneums below the ileal conduit were sutured to "bottom out" the gap between the ileal conduit and the right abdominal wall in addition to standard procedures. The recovery of intestinal function and incidence of bowel obstruction were compared between the two groups. 【Results】 In the conventional group, the intestinal function recovered within 2 to 6 days after surgery, with a median ventilation time of 3 days. Intestinal obstruction occurred in 3 patients, 2 of whom improved after conservative treatment while 1 underwent surgical exploration after ineffective conservative therapy. There were no significant differences in the time of discharge and ventilation between the two groups, but no intestinal obstruction occurred in the modified group. 【Conclusion】 Peritoneal externalization at the end of ileal passage can reduce the incidence of intra-abdominal hernia and postoperative intestinal obstruction, which is worthy of clinical application.

ABSTRACT

OBJECTIVES@#To evaluate the feasibility and safety of bipolar-plasmakinetic transurethral enucleation and resection of the prostate (B-TUERP) in day surgery.@*METHODS@#From January 2021 to August 2022, 34 patients with benign prostatic hyperplasia (BPH) underwent B-TUERP in day surgery in the First Affiliated Hospital of Anhui Medical University. Patients completed the screening and anesthesia evaluation before admission and received the standard surgery which implements "anatomical enucleation of the prostate" and "absolute bleeding control" on the same day of admission, and by the same doctor. Bladder irrigation was stopped, catheter was removed and the discharge evaluation was performed on the first day after operation. The baseline data, perioperative conditions, time of recovery, treatment outcomes, hospitalization costs, and postoperative complications were analyzed.@*RESULTS@#All operations were successfully conducted. The average age of the patients was (62.2±7.8) years, average prostate volume was (50.2±29.3) mL. The average operation time was (36.5±19.1) min, the average hemoglobin and blood sodium were decreased by (16.2±7.1) g/L and (2.2±2.0) mmol/L, respectively. The average postoperative length of hospital stay, and total length of hospital stay were (17.7±2.2) and (20.8±2.1) h, respectively, and the average hospitalization cost was (13 558±2320) CNY. All patients were discharged on the day after surgery except for one patient who was transferred to a general ward. Three patients received indwelling catheterization after catheter removal. The 3-month follow-up results showed a substantial improvement in the International Prostate Symptom Score, quality of life score and maximum urinary flow rate (all P<0.01). Three patients experienced temporary urinary incontinence, 1 patient experienced urinary tract infection, 4 patients were diagnosed with urethral stricture and 2 patients experienced bladder neck contracture. No complications above Clavien grade Ⅱ occurred.@*CONCLUSIONS@#The preliminary results showed that B-TUERP ambulatory surgery is a safe, feasible, economical and effective treatment for appropriately selected patients with BPH.

ABSTRACT

Objective:To analyzed the urinary microbiota characteristics of upper tract urothelial carcinoma(UTUC) patients.Methods:Urine samples were collected from 23 patients with UTUC (UTUC group) and 22 patients with benign diseases (control group) admitted to Yijishan Hospital, the First Affiliated Hospital of Wannan Medical College from July 2021 to July 2022. The differences in age [(60.9±5.7) years vs. (61.4±8.8) years], sex (male/female: 15/8 vs. 9/13), and body mass index [(22.9±1.8) kg/m 2 vs. (23.4±1.7) kg/m 2] between the UTUC group and the control group were not statistically significant ( P>0.05). The V4 region of the 16S rRNA of urinary microorganisms was sequenced using the Illumina NovaSeq6000, and the results were processed using QLLME2. Differences in α-diversity between groups were analyzed by using the Shannon, Simpson, and Chao1 indices. Differences in β-diversity between groups were analyzed by using unweighted principal coordinates analysis (PCoA). Linear discriminant analysis Effect Size(LEfSe)was used to identify the bacterial taxa with different abundances between groups. Significant differences were defined as LDA>2. Results:The Chao1 index (703.12±265.54 vs. 506.20±214.02) and Shannon index (5.61±1.85 vs. 5.07±1.34) were significantly higher in the UTUC group compared to that in the control group ( P<0.05). The α-diversity of urinary microbes was elevated in the UTUC group compared to that in the control group but the difference in β-diversity was not statistically significant ( P=0.161). The enrichment of Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae abundance was higher in the urine of UTUC patients(LDA > 2). Further subgrouping analyses of the UTUC patients showed that the differences in Chao1 index (706.44±271.84 vs. 784.09±272.72), Shannon index (6.04±1.30 vs. 5.91±1.67), and Simpson index (0.94±0.08 vs. 0.89±0.22) between the muscle-invasive group and the non-muscle-invasive group were not statistically significant ( P>0.05). The difference in α-diversity between muscle-invasive and non-muscle-invasive group was not statistically significant, but the difference in β-diversity was statistically significant ( P=0.047). The urinary microbial communities of Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were enriched in muscle-invasive group and differed from that in non-muscle-invasive group(LDA>2). Conclusions:This study suggests that the urinary microbial community was more abundant in UTUC patients than in non-UTUC patients and that Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae were more abundant in the urine of UTUC patients. The urinary microbial community was more abundant in the urine of non-muscle-invasive patients than in the muscle-invasive patients, and Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were more abundant in the urine of non-muscle-invasive patients.

ABSTRACT

Objective:To evaluate the safety and efficacy of bipolar plasmakinetic endoscopic enucleation of the prostate (BEEP) in the treatment of benign prostatic hyperplasia (BPH) in a day surgery mode.Methods:The clinical data of 162 BPH patients admitted to the First Affiliated Hospital of Anhui Medical University from January 2021 to June 2022 were analyzed retrospectively. The patients were divided into day group(80 cases) and conventional group(82 cases) according to hospitalization mode. In the day group, preoperative screening and anesthesia evaluation was completed during the pre-hospitalization period, and the patient was discharged within 24 hours. The two groups were treated with BEEP, the urethral mucosa was cut at a " Ω" 5 mm proximal to the external sphincter ring in front of the verumontanum. Following the standard of anatomical enucleation of the prostate, the gland tissue was cut out after enucleation. There were no significant differences in age [(63.6±8.9) years vs. (67.5±7.1) years], body mass index [(24.3 ±2.6) kg/m 2vs. (23.0±3.2) kg/m 2], prostate volume [(55.8±16.9) ml vs. (53.7±20.7) ml], preoperative prostate-specific antigen [3.8(1.2, 5.3)ng/ml vs. 3.5(2.1, 5.6)ng/ml], the international prostate symptom score (IPSS) [(25.9±5.2) vs. (26.3±5.9)], the quality of life score (QOL) [(5.0±0.7) vs.(5.0±0.6)], the maximum urine flow rate (Q max) [(8.2±4.5) ml/s vs. (7.9±4.1) ml/s] and residual urine volume (PVR) [49(0, 131) ml vs. 45(11, 106) ml] between the two groups ( P>0.05). The waiting time before admission was [(2.6±1.2) d vs. (5.3±1.5) d], and the difference between the two groups was statistically significant ( P<0.05). The perioperative efficacy indicators, total hospitalization expenses and short-term postoperative complications were compared between the two groups. Results:In this study, all patients successfully completed the operation. There were no statistical significances in the perioperative indicators between the day group and the conventional group including the operation time [(38.4±15.2) min vs. (40.4±13.9) min], enucleated tissue weight [(34.6±9.6) g vs. (35.4±10.8) g], the decrease value of hemoglobin [(13.0±2.5) g/L vs. (12.0±3.7) g/L] and the decrease value of blood sodium [(2.2±0.9) mmol/L vs. (2.4±1.3) mmol/L]( P>0.05). The significant differences were observed in bladder irrigation time [(16.9±2.1)h vs. (22.7±12.1)h], catheterization time [(18.8±5.1) h vs.(65.6±13.0)h], postoperative hospital stay [(16.8±2.4)h vs. (64.8±6.3)h] and the total hospitalization expenses [(13 282.2±2 236.3) yuan vs. (15 969.3±2 420.6) yuan] between the day group and the conventional group ( P < 0.01). In the day group, 1 case was transferred to the general ward for observation for 1 day. There were no significant differences in the incidence of complications as urinary retention [6.3% (5/80) vs. 3.7% (3/82)], temporary incontinence [2.5% (2/80) vs. 2.4%(2/82)], urethra stricture [7.5% (6/80) vs. 6.1% (5/82)], and hematuria for intervention [1.3% (1/80) vs. 1.2% (1/82)]between the day group and the conventional group ( P > 0.05). After 6 months of follow-up, there were no significant differences in IPSS[(6.7±2.8) vs. (6.1±2.5)], QOL[(1.8±0.9) vs. (2.0±0.8)], Q max [(26.4±5.5)ml/s vs. (25.8±4.6)ml/s] and PVR [7(2, 11)ml vs. 5(4, 8)ml] between the two groups at 6 months after operation ( P > 0.05), but there were significant improvements when compared with those items of preoperation ( P < 0.01). Conclusions:The treatment of BPH with BEEP in the day surgery mode is as safe and effective as that in the conventional surgery mode, with little bleeding, high resection efficiency, definite therapeutic effect and low incidence of complications. BEEP can shorten the length of hospital stay and reduce medical expenses in the day surgery mode, and can be carried out in hospitals with conditions.

ABSTRACT

Laparoscopic renal pedicle lymphatic disconnection is the most effective method for treating chyluria that has failed to respond to conservative management. Chylous hemothorax is a rare clinical occurrence resulting from the anatomic abnormality. This paper reported a case, who was admitted with painless gross hematuria for 1 month and was diagnosed with left chylous hematuria. Laparoscopic left renal pedicle lymphatic disconnection was performed, and bilateral chylous hemothorax occurred after the operation. After conservative treatment such as bilateral closed thoracic drainage and blood transfusion support, the patient recovered well. After 2 months of follow-up, there was no obvious effusion in the bilateral thoracic cavity, and the chylous test of urine fluid was negative.

ABSTRACT

Abstract@#Chronic prostatitis is one of the common diseases in male urology.The disease of type Ⅲ prostatitis (chronic prostatitis / chronic pelvic pain syndrome) in the classification of prostatitis in the National Institutes of Health (NIH) cannot reflect the nature of the disease,such as unclear etiology and pathogenesis,diverse clinical manifestations,insufficient diagnostic basis,etc.The concept of type Ⅲ prostatitis does not regard the pelvic floor and lower urinary tract as a functional whole.Therefore,the China Chronic Prostatitis Diagnostic Criteria and Effi- cacy Evaluation Collaborative Group proposed to change the name of type Ⅲ prostatitis to prostatic pelvic syndrome and explore the establishment of symptom-based diagnostic and efficacy evaluation criteria to reflect the nature of the disease and meet the treatment objectives of type Ⅲ prostatitis patients to improve symptoms and improve quality of life.The proposal of new theories and the development of multi-center clinical trials will help urologists deepen their understanding of the prostatic pelvic syndrome and help them to correctly diagnose and treat the syndrome.

ABSTRACT

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is one of the common diseases in uroloandrology, which recurs easily after treatment. In recent years, the safety and efficacy of extracorporeal shock wave therapy (ESWT) for CP/CPPS has been widely demonstrated. Studies have shown satisfactory short-term (≤12 weeks) outcomes of ESWT, but lack long-term (>12 weeks) follow-up data. In addition, inconsistent indications and unexplained therapeutic mechanisms have limited the further clinical promotion of ESWT. This article summarizes the latest progress and potential mechanism of ESWT in the treatment of CP/CPPS in order to provide new insights for the standardized application of ESWT.

ABSTRACT

Nephroureterectomy is the golden standard for surgical treatment of upper urinary tract urothelial carcinoma. With the development of surgical robotics, the number of robot-assisted laparoscopic nephroureterectomy has increased rapidly worldwide. With the advantages of 3D imaging, high-definition camera and flexible joints, this procedure reduces the complexity of approaches in nephroureterectomy such as dissection of distal and intramural ureter as well as suture of the bladder wound, with comparable oncological outcome to open surgery. The present article reviewed the research progress in preoperative preparation, intraoperative technique, perioperative parameters and prognosis of robot-assisted laparoscopic nephroureterectomy.

ABSTRACT

Objective:To investigate the characters and emergency treatment strategy of upper urinary tract stone obstruction complicated with urosepsis.Methods:Clinical data of 28 cases of urosepsis, caused by upper urinary tract stone obstruction and arranged for emergency admission in our hospital during January 2018 to December 2019, were retrospectively analyzed. There were 6 males and 22 females. The median age was 54(32-93)years old. All patients had fever with the temperature ranged from 38.5 to 41.0 ℃. The median course of disease was 3 (ranging 1-14) days. The systolic blood pressure ranged from 76 to 138 mmHg at admission. Hypotension group was defined as the systolic blood pressure<90 mmHg after admission. Normotensive group was defined as the systolic blood pressure≥90 mmHg. There were 12 cases in hypotension group, including 3 males and 9 females. The median age was 57 (ranging 32-93) years old. The stones located at left side in 7 cases and right side in 5 cases. The stones located at the upper ureter in 5 cases, middle ureter in 2 cases, lower ureter in 4 cases and renal calculi in one case. The median length of the stone was 10 (ranging 6-20) mm. Six cases suffered with diabetes mellitus. One case suffered with neuron system disease. 3 cases have history of recent extracorporeal shock wave lithotripsy(ESWL). There were 16 cases in normotensive group, including 3 males and 13 females with the median age of 53 (ranging 33-76) years old. The stones located at left side in 5 cases, right side in 9 cases and bilateral in 2 cases. The stones located at the upper ureter in 10 cases, middle ureter in 4 cases, lower ureter in 2 cases. The length of the stone was 10 (ranging 8-14) mm. There were 3 cases with neurological diseases and 3 cases with recent ESWL history. There was significant difference between hypotension group and normotensive group in ration of diabetes mellitus ( P=0.024). Blood routine examination, C-reactive protein (CRP), procalcitonin(PCT), blood and urine bacterial culture were performed in both groups. The patients were treated with empiric antibiotics after the evaluation based on the sequential organ failure assessment (SOFA). Patients with hypotension were given blood volume expansion, and vasoactive drugs were added when the blood pressure was still low. After the blood pressure was stable, the collection system decompression was performed. The difference of infection indicators and therapeutic methods between the two groups was compared. Results:There was no significant difference in median WBC [16.34 (2.55-41.65) × 10 9/L vs. 13.97(6.23-26.65) × 10 9/L, P=0.577], median CRP [143.0(74.2-200.0) ng/ml vs.110.0 (22.7-200.0) ng/ml, P=0.771] between hypotension group and normotensive group. The difference of PCT [95.5 (26.5-200.0) ng / ml vs. 57.6 (1.0-200.0) ng / ml, P=0.040] and PLT [65.5(14.0-170.0)×10 9/L vs. 73.0(17.0-412.0)×10 9/L, P=0.030] between hypotension group and normotensive group was statistically significant. The median SOFA scores of hypotension group and normotensive group were significantly different [8.5(3.0-13.0) vs. 5.0(2.0-8.0), P=0.001]. Ureteral stent placement was performed in 23 cases, and nephrostomy was performed in 5 cases. There was no significant difference in surgical drainage between the two groups ( P=0.887). Eight patients in hypotension group were admitted to ICU. There was no significant difference in the duration of antibiotic use between hypotension group and normotensive group [8 (3-12) d vs. 5 (3-7) d, P=0.453]. Sepsis was cured in both groups after decompression, fluid resuscitation and antibiotic treatment. Conclusions:In severe cases of upper urinary tract stone obstruction complicated with urogenic sepsis, septic shock may occur. The condition is urgent, severe and dangerous. Patients with hypotension had higher PCT and SOFA scores, and lower PLT. It is very important to carry out the collection system decompression drainage in time, liquid resuscitation, early effective antibiotic use.

ABSTRACT

Prostatitis is one of the common diseases of uro-andrology. There are still many deficiencies in the existing classification methods of prostatitis. In traditional classification criteria, the etiology of "nonbacterial prostatitis" is not clear, and it is easily confused with "prostate pain" . NIH classification relies on the Meares-Stamey 4-glass test, which is complex and with a high false-positive rate, thus limiting its clinical application. In addition, the WBC count in prostate fluid could not reflect the actual condition of the disease. The concept of type Ⅲ prostatitis, or chronic prostatitis/chronic pelvic pain syndrome, does not regard the pelvic floor and lower urinary tract as a functional entirety. Renaming type Ⅲ prostatitis into prostate-pelvic syndrome, exploring and establishing the symptom-based criteria of diagnosis and efficacy assessment, would better reflect the intrinsic nature of the disease, and meet the therapeutic goals to relieve symptoms and improve quality of life in type Ⅲ prostatitis patients.

ABSTRACT

Objective:To evaluate the clinical efficacy and safety of transurethral columnar balloon dilation of prostate (TUCBDP) in treatment of patients with benign prostatic hyperplasia(BPH).Methods:A retrospective analysis was performed on 25 cases of BPH treated by TUCBDP in the First Affiliated Hospital of Anhui Medical University from June 2016 to July 2018. The median age was 80(57-94) years, and the median volume of prostate was 75 (30-176) ml. The median preoperative maximum urine flow rate (Q max) was 6 (2-9) ml/s, the median quality of life score (QOL)was 4(3-5) points. The median preoperative international prostate symptom score (IPSS) and residual urine volume (RUV) was 25(18-34) and 85 (30-510) ml respectively.The median preoperative international index of erectile function questionnaire-5 (IIEF-5) score was 11(5-21)points and the median preoperative premature ejaculation diagnostic tool (PEDT) score was 10(6-17)points.The standard procedure of TUCBDP includes injecting 5ml of normal saline into the inner capsule, touching the inner capsule at the apex of prostate, fixing the catheter and then injecting water into the outer capsule to make the pressure reach 2.5 kPa. When the pressure of the outer capsule was maintained at 3 kPa for 5 minutes, the prostate was split. The peroperative IPSS, QOL, Q max and RUV was compared. The IIEF-5 and PEDT score before and after surgery were compared in patients with normal sexual activity to evaluate whether there were reverse ejaculation and semen reduction. Results:One case of BPH failed to rupture and the other two cases was split at 6 o’clock. The three cases were converted to plasma resection. The rest 22 cases were operated successfully with the median operation time of 17(11-23)min, the hemoglobin loss of 19(15-22)g/L. The continuous bladder flushing time was 1(1-2)d, the indwelling catheter time was 10(7-11)d and the hospital stay time was 11(7-12)d. Twenty of 25 cases were followed-up for 12 months. IPSS was 8 (4-14) points, Q max was 17(9-25)ml/s, and RUV was 10 (0-150) ml; there were significant differences between the peroperative and postoperative (all P<0.001). The median QOL was 1(1-2) point, decreased than peroperative( P<0.05). No adverse ejaculation and semen reduction were found in the post-operative patients with normal sexual life. The post-operative IIEF-5 and PEDT score was 16 (7-24) points and 8 (6-14) points respectively, which was not significantly different while compared with pre-operative IIEF-5 and PEDT score. Conclusions:TUCBDP was proved to be effective and safe for treating high-risk BPH patients with the advantages of short operation time, less bleeding, significant improvement of residual urine and dysuria.

Objective:To explore the therapeutic effect of low-intensity extracorporeal shock wave (Li-ESW) in model rats with chronic prostatitis and its optimal parameters.Methods:From April to August 2019, 90 healthy male SD rats aged 8 weeks were randomly divided into control group (group C, n=15), model group (group M, n=15) and shock wave treatment group (group T, n=60), which were treated with Li-ESW after being modeled successfully. The rats in group T were supine and treated with focused Li-ESW, and the probe was placed above the anatomical position of the prostate. Treatment scheme was 3 Hz of frequency, 500 pulses, and once a week for 4 weeks. Group T was divided into group T1(0.09 mJ/mm 2), T2(0.20 mJ/mm 2), T3(0.30 mJ/mm 2) and T4(0.40 mJ/mm 2) according to energy flux density, with 15 rats in each group. Before the establishment of the model, the rats in each group were tested with von Frey fiber of 2 g, 4 g and 6 g at the scrotum respectively, and the positive reaction was recorded. There was no significant difference between the three groups ( P>0.05). After one week, the rat model with CP was established by injecting 3% carrageenan into the bilateral lobes of the prostate under anesthesia. And one week after the modeling was completed, the rats in each group underwent von Frey test again to measure pain and evaluate the modeling effects. Group T was then treated once a week for a 4-week period. During the treatment, von Frey test was performed before each treatment to evaluate the treatment effect of the previous week. After the von Frey test for one, two and four weeks of treatment, 5 rats were sacrificed in each group, and the bilateral lobes of the prostate were dissected under aseptic conditions for paraffin inclusion and HE staining. Result:The positive reaction in group M and each group T was significantly more than those in group C ( P<0.001) one week after the modeling was completed, and there was no significant difference between group M and group T. The number of positive reactions in group T2 was lower than that in group M at each time point after treatment ( P<0.05), and it is also less in group T1, T3 and T4 were than that in group M after 3 weeks, 3 and 4 weeks and 2 weeks respectively( P<0.05). In group T2, the number of positive reactions began to decrease after 1 week of treatment, and reached the lowest after 4 weeks, with significant difference in pain measurement results at different time points ( P<0.05). The results of pathological examination showed that there were more inflammatory cells in prostatic stroma and disordered arrangement of epithelial cells in group M than that in group C. The pathological scores of group M, T1, T2, T3 and T4 were 8, 7, 4, 6, 9 after 1 week treatment, 8, 5, 3, 4, 7 points after 2 weeks treatment, and 7, 3, 2, 4, 7 points after 4 weeks treatment, respectively. Conclusions:Low-intensity extracorporeal shock wave treatment had a significant effect on the improvement of symptoms in model rats with chronic prostatitis. Under the scheme of frequency 3 Hz, 500 pulses, once a week for 4 weeks, the optimal parameters is 0.20 mJ/mm 2.

ABSTRACT

Objective To explore the potential value of applying three-dimensional visualization technology in the robot-assisted laparoscopic nephron sparing partial nephrectomy.Methods From January to December 2018,98 patients with renal carcinoma undergoing robot-assisted laparoscopic nephron sparing surgery were retrospectively analyzed.Forty-one patients in the experimental group accomplished kidney CT examination and three-dimensional reconstruction before surgery,and fifty-seven patients in the control group only completed kidney CT examination.There were 20 males and 21 females in the experimental group with the age of (51.39 ± 14.80) years and body mass index (BMI) of (23.54 ± 3.08) kg/m2.The median tumor diameter was 3.40 cm (range 1.90-8.30 cm) and the mean R.E.N.A.L.score was (5.83 ± 1.51) in the experimental group including 11 cases of transperitoneal,17 cases of retroperitoneal and 13 cases of combined transperitoneal and retroperitoneal access.There were 35 males and 22 females in the control group with the age of (52.84 ± 12.28) years and BMI of (24.01 ±3.30)kg/m2.The median tumor diameter was 3.35 cm (range 1.40-7.0 cm) and the mean R.E.N.A.L.score was (6.17 ± 1.77) in the control group including 15 cases of transperitoneal,31 cases of retroperitoneal and 11 cases of combined transperitoneal and retroperitoneal access.There was no statistical difference between two groups in term of age,gender,BMI score,R.E.N.A.L.score,tumor size,tumor location and operative approach.Results Ninety-eight cases of operation were successfully completed without causing vascular and ureteral injury.The warm ischemia time in the experimental group was significantly shorter than that of the control group [median 15.0 (7.0-26.0) min vs.20.0 (10.0-28.0) min,P--0.02],while no statistical difference was observed in term of operation time [median 130.0 (65.0-340.0) min vs.139.0 (67.0-250.0) min,P =0.22].There was no significant difference between the two groups in the decrease of hemoglobin within 24 hours after operation [median 20.0 (4.0-39.0) g/L vs.15.5 (2.0-40.0) g/L,P =0.56] and the average length of hospital stay after operation [median 6.0(4.0-14.0) d vs.6.0(5.0-14.0) d,P =0.86].The trend of creatinine declining was not statistically significant between the two groups at both 24 hours [median:2.0 (-10.0-28.0) μmol/L vs.7.5 (-17.0-51.0) μ mol/L,P =0.24] and 6 months after operation [median:2.0 (-12.0-57.0) μ mol/L vs.4.5 (-3.0-24.0) μmol/L,P =0.39].Conclusions Preoperative three-dimensional reconstruction is helpful to shorten the warm ischemia time,but it did not show short-term and long-term protection for renal function.

ABSTRACT

Objective To investigate the clinical significance of second transurethral resection of bladder tumor and analyze the related risk factors of recurrence and progression of bladder tumor.Methods A retrospective analysis of 171 patients including 134 males and 37 females.95 patients were enrolled in single TURBT group.The patients were (64.4 ± 10.7) years old.Their mean body mass index (BMI) was (23.5 ± 3.0) kg/m2 and mean tumor diameter was (24.7 ± 8.8) mm.67 cases were diagnosed with Ta stage and 28 cases were diagnosed with T1 stage.There were 44 cases diagnosed with low grade tumor and 51 cases with high grade tumor.76 patients were enrolled in second TURBT group.The patients were (66.0 ± 9.2) years old.Their mean BMI was (23.7 ± 3.0) kg/m2 and mean tumor diameter was (25.3 ± 9.3)mm.44 cases were diagnosed with Ta stage and 32 cases were diagnosed with T1 stage.There were 41 cases diagnosed with low grade tumor and 35 cases with high grade tumor.There was no significant difference between the two groups(P > 0.05).General anesthesia was used for the operation,and the patient was in lithotomy position.For the first TURBT,the standard transurethral resection method was used to resect the tumor and the surrounding mucosa 1-2 cm far from tumor.The tumor size,location and number were recorded.The second resection was performed 2 to 12 weeks after the operation,and the basal part of the original tumor,the inflammatory edema mucosa around the original tumor and other suspicious tumor sites were sequentially removed.Both groups received immediate intravesical instillation chemotherapy with epirubicin or gemcitabine within 24 hours after surgery.The perfusion protocol was started once a week for 8 times;then once a month upto 1 year after surgery.Univariate and multivariate analysis were used to analyze the related factors of bladder tumor residual after first TURBT and the related risk factors of postoperative recurrence and progression.The time of second TURBT was analyzed.The Kaplan-meier method was used to draw the survival curve and analyze the effect of secondary resection on the survival of patients with bladder tumor.Results 17 cases of residual tumor were found in the second TURBT group,including 9 cases with Ta stage and 8 cases with T1 stage.Among them,5 cases in Ta stage were upgraded to T1 stage,and the remaining 12 cases keep the same pathological stage.There was no significant difference in the residual rate between Ta and T1 (11.8% vs.10.5%,P > 0.05).Multivariate analysis showed that the number of tumors (OR 4.255,95% CI 1.186-16.124,P =0.034),tumor size (OR 7.800,95% CI 1.852-32.841,P =0.005),and pathological grade (OR 3.764,95% CI 0.947-14.968,P =0.006) were risk factors for residual tumor.Univariate analysis showed that secondary TURBT,BMI,tumor size,clinical stage,and pathological grade were the influencing factors of bladder tumor recurrence and progression (P < 0.05).Multivariate analysis showed that single TURBT (OR 0.25,95% CI 0.135-0.561,P =0.000),tumor diameter ≥ 30 mm (OR 3.548,95 % CI 1.899-6.629,P =0.000),high grade tumor (OR 2.62,95% CI 1.026-4.990,P =0.043) are independent risk factors for tumor recurrence.Single TURBT (OR 0.114,95% CI 0.033-0.391,P =0.001),tumor diameter ≥ 30 mm (OR 4.026,95% CI 1.628-9.956,P =0.003),clinical stage T1 (OR 5.623,95% CI 1.818-17.385,P =0.003) are independent risk factors for tumor progression.The recurrence-free survival time of the first and second resection intervals ≤6 weeks and > 6 weeks was 22.6 months and 17.8 months,respectively (P < 0.05),and the progression-free survival time was 23.4 months and 22.3,respectively (P > 0.05).The follow-up period was 3 to 31 months with an average of 16.7 months.The recurrence-free survival time of the single TURBT group and the second TURBT group was 19.4 months and 23.8 months,respectively (P < 0.05).Tumor progression occurred in 25 patients with 22 in the single TURBT group and 3 in the second TURBT group.The progression-free survival time was 22.1 months and 24.7 months,respectively (P < 0.05).Conclusions Second transurethral resection of bladder tumor can reduce postoperative residual tumor,postpone postoperative recurrence and progression,and improve prognosis of the patients.
