ABSTRACT
【Objective】 To analyze the causes of the failure of previous operations in female patients with stress urinary incontinence (SUI), and to evaluate the efficacy and safety of modified transobturator outside-in tape (TOT). 【Methods】 A total of 42 female SUI patients who had failed in previous anti-incontinence surgery during Aug.2016 and Jul.2022 were enrolled. The causes of failure were analyzed. All patients were treated with modified TOT, and the operation time, estimated blood loss, duration of catheterization, symptom improvement and complications were observed. The outcomes were evaluated with the International Consultation on Incontinence Questionnaire Short Form (ICI-Q-SF), pad test and urodynamic study. 【Results】 All operations were technically successful. The average operation time was (32.4±18.6) min, and estimated blood loss was (54.2±34.5) mL. There were no obvious complications. After operation, the ICI-Q-SF score significantly decreased (P0.05). The overall effective rate was 88.1%. 【Conclusion】 Modified TOT can be used for the treatment of patients with failed anti-SUI surgery, which is simple and easy to perform, with a low complication rate and satisfactory postoperative results.
ABSTRACT
Objective:To investigate the efficacy and safety of transurethral Moses holmium laser enucleation of the prostate (MoLEP) in the treatment of small-volume benign prostatic hyperplasia (BPH).Methods:The clinical data of 132 patients with small BPH (prostate volume <40 ml) who underwent MoLEP from October 2017 to April 2020 in the First Affiliated Hospital of Nanjing Medical University were analyzed retrospectively.The age of the patients was (63.93±5.21) years old, including 12 patients with cystolithiasis. The prostate volume of 132 patients was (32.16±7.81) ml, the preoperative international prostate symptom score (IPSS) was 23.00(15.00-34.00), the quality of life score (QOL) was 5(2-6), the maximum urinary flow rate (Q max) was 7.80(0.80-9.80)ml/s and residual urine volume (PVR) was 158(51-409) ml. 89 patients had the preoperative maximum detrusor contractility (64.23±8.11) cmH 2O. Surgical methods: the 120 W Moses laser platform(Lumenis Inc)was used, the cutting power was adjusted to 80 W (2.0J×40Hz) (narrow pulse width mode), and the hemostatic power 24W (0.8J×30Hz) (wide pulse width mode). Patients with bladder calcifications underwent Moses laser bladder stone lithotripsy.After the initial resection by the level of verumontanum was performed, an anatomic plane was exposed and carried forward until the bladder neck. If prostate stones were found, Moses holmium laser lithotripsy can be performed directly. After operation, the bladder was continuously flushed with normal saline. The catheter was removed 24 hours after the operation. The operation status, intraoperative and postoperative complications were recorded. IPSS, QOL, Q max and PVR were followed up 3 months after surgery. Postoperative urinary incontinence is defined as the need for 2 pads or more within 24 hours. Results:The operations of 132 cases (including 12 cases with bladder stones) were successfully completed. 30 cases with prostate calcifications were found during the operation. The operation time (enucleation time) was (16.83±4.03) min. There were no perioperative complications such as blood transfusion, transurethral resection syndrome, urinary retention and venous thromboembolism. No bladder neck contracture or recurrence of bladder stones was found after surgery. Postoperative urethral stricture occured in 2 cases (1.5%), and postoperative urinary incontinence in 27 cases (20.5%). There were 102 cases (77.3%) with chronic interstitial inflammatory cell infiltration. Three months after operation, IPSS was 7(0-14), QOL was 2(0-5), Q max was 17.55(9.40-26.50)ml/s and PVR was 27(0-46) ml, which were significantly improved compared with preoperatively( P<0.05). Conclusions:MoLEP can significantly improve lower urinary tract symptoms (LUTS) and life quality of patients with small-volume BPH.At the same time, the incidence of complications such as urethral stricture and urinary incontinence is lower. The operation is safe and reliable, and bladder stone lithotripsy can be performed at the same time.
ABSTRACT
Objective:The clinical efficacy, safety and quality of life in female patients with stress urinary incontinence (SUI)treated by midurethral sling were studied by multicenter retrospective study.Methods:From January 2018 to December 2018, 531 female patients with severe stress urinary incontinence from seven domestic urinary center were included in this study, including 78 cases from General Hospital of Central Theater Command, 122 cases from Shanghai Jiao tong University School of Medicine Affiliated Ren Ji Hospital, 67 cases from Shanghai Jiaotong University Affiliated First People’s Hospital, 68 cases from People’s Hospital of Jiangsu Province, 71 cases from The First Affiliated Hospital of Xi’an Jiaotong University, 65 cases from Zhejiang Provincial People’s hospital, 60 cases from Xiamen University First Affiliated Hospital. Among the 531 patients, 214 cases received TVT sling with an average age of (58.14±10.16) years. 181 cases were in postmenopausal(84.6%). The number of births ≥2 times was 89 (41.6%) cases. The score of ICI-Q-SF was 16.00±1.73. There were 166 cases of moderate incontinence (77.6%) and 48 cases of severe incontinence (22.4%). There were 317 patients in the TOT/TVT-O group with an average age of (58.33±10.25) years. 247 cases were in postmenopausal(77.9%). The number of births ≥2 times was 120 (37.8%) cases. The score of ICI-Q-SF was 15.79±1.75. There were 256 cases of moderate incontinence (80.8%) and 61 cases of severe incontinence (19.2%). There was no statistically significant difference in general data parameters between the two groups ( P>0.05). 1, 6, 12 months after the operation, the two groups of patients incontinence questionnaire Summary(ICI-Q-SF), common complications and Patient Global Impression of Improvement(PGI-I), satisfaction evaluation follow-up. ICI-Q-SF score improved > by 50% (cure + significant improvement) and 1-hour pad test <10 g (qualitative index) were used as the evaluation index of surgical success. Result:Both of the two surgical methods have high successive rate. There was no significant difference between 94.9% (203/214) of the TVT group and 93.7% (297/317) of the TOT/ TVT-O group ( P>0.05). Postoperative improvement of urinary incontinence (cure rate) [88.3% (189/214)]in the TVT group was slightly higher than that in the TOT/ TVT-O group [77.0% (244/317)] ( P<0.05). There was no change in the recurrence rate of urinary incontinence in the follow-up 6 and 12 months after the operation. There was no statistically significant difference between 4.4% (9/203) in the TVT group and 5.4% (16/297) in the TOT/TVT-O group ( P>0.05). The subjective cure rate 12 months after the operation was 96.3% (206/214) in the TVT group and 95.9% (304/317) in the TOT/TVT-O group ( P>0.05). 10 patients occurred bladder perforation occurred in the TVT group, and no bladder perforation occurred in the TOT/TVT-O group ( P<0.001). The incidence of pain and discomfort in the TVT group was significantly lower at 1.9% than that in the TOT/TVT-O group at 6.9% ( P<0.01). There was no statistically significant difference between the two groups in the incidence of complications such as dysuria/urinary retention, frequent urination/urgency incontinence. Both of them exposed sling ( P>0.05). Conclusion:Both TVT and TOT/TVT-O sling can effectively treat female stress urinary incontinence, and both can improve the sexual satisfaction of patients after the surgery, with fewer complications and other advantages. The selection of specific surgical methods in clinical practice can be individualized according to the patient's physical conditions, clinical needs and the operation methods familiar to doctors.
ABSTRACT
<p><b>OBJECTIVE</b>To study the technique and clinical outcomes of laparoscopic radical prostatectomy for high risk prostate cancer.</p><p><b>METHODS</b>A total of 65 patients with high risk prostate cancer were treated with surgery in the First Affiliated Hospital of Nanjing Medical University from January 2011 to June 2013. The mean age was 67 years (range 45-75 years). The mean preoperative prostate specific antigen (PSA) level was 26.7 µg/L (range 11.2-65.5 µg/L). The transrectal biopsy revealed Gleason score of 3+3 in 4 patients, Gleason 3+4 in 27 patients, Gleason 4+3 in 11 patients, Gleason 4+4 in 21 patients and Gleason 4+5 in 2 patients. The bone metastasis was excluded by scintigraphy examination. The surgical procedures were performed through transperitoneal approach. Extended pelvic lymph nodes dissection was performed after the removal of the prostate. Adjuvant radiotherapy or hormonal therapy was administrated according to the pathological results. Serum PSA was detected every 1 to 2 month and urinary continence was evaluated every 3 month in the first year, and then serum PSA was detected every 2 to 3 month.</p><p><b>RESULTS</b>The mean operative time was (134±21) minutes and the median blood loss was (300±146) ml. Bladder neck reconstruction was performed in 15 cases. The drainage was removed on postoperative day 4 and the catheter was removed on day 7. Pathologic results demonstrated pT2 in 25 patients, pT3a in 28 patients, pT3b in 9 patients and pT4 in 3 patients. Positive surgical margin was presented in 15 patients. A median of 19 lymph nodes (range 11-24 nodes) were retrieved during lymphadenectomy and 11 patients had lymph nodes metastasis with a total of 19 positive nodes. Forty-three patients recovered continence after the removal of catheter. Eleven patients received adjuvant hormonal therapy and 19 patients received adjuvant radiation therapy. With the median of 20 months follow-up (range 12-30 months), 5 patients got biochemical recurrence.</p><p><b>CONCLUSIONS</b>Laparoscopic radical prostatectomy with extended lymph nodes dissection for high risk prostate cancer is safe and technical feasible. It provides accurate information on tumor stage and grade. It is an important component of multimodality for the treatment of high risk prostate cancer.</p>

<p><b>BACKGROUND</b>Over the past two decades, the clinical presentation of renal masses has evolved, where the rising incidence of small renal masses (SRMs) and concomitant minimal invasive treatments have led to noteworthy changes in paradigm of kidney cancer. This study was to perform a proportional meta-analysis of observational studies on perioperative complications and oncological outcomes of partial nephrectomy (PN) and radiofrequency ablation (RFA).</p><p><b>METHODS</b>The US National Library of Medicine's life science database (Medline) and the Web of Science were exhaustly searched before August 1, 2013. Clinical stage 1 SRMs that were treated with PN or RFA were included, and perioperative complications and oncological outcomes of a total of 9 565 patients were analyzed.</p><p><b>RESULTS</b>Patients who underwent RFA were significantly older (P < 0.001). In the subanalysis of stage T1 tumors, the major complication rate of PN was greater than that of RFA (laparoscopic partial nephrectomy (LPN)/robotic partial nephrectomy (RPN): 7.2%, open partial nephrectomy (OPN): 7.9%, RFA: 3.1%, both P < 0.001). Minor complications occurred more frequently after RFA (RFA: 13.8%, LPN/RPN: 7.5%, OPN: 9.5%, both P < 0.001). By multivariate analysis, the relative risks for minor complications of RFA, compared with LPN and OPN, were 1.7-fold and 1.5-fold greater (both P < 0.01), respectively. Patients treated with RFA had a greater local progression rate than those treated by PN (RFA: 4.6%, LPN/RPN: 1.2%, OPN: 1.9%, both P < 0.001). By multivariate analysis, the local tumor progression for RFA versus LPN/RPN and OPN were 4.5-fold and 3.1-fold greater, respectively (both P < 0.001).</p><p><b>CONCLUSIONS</b>The current data illustrate that both PN and RFA are viable strategies for the treatment of SRMs. Compared with PN, RFA showed a greater risk of local tumor progression but a lower major complication rate, which is considered better for poor candidates. PN is with no doubt the golden treatment for SRMs, and LPN has been widely accepted as the first option for nephron-sparing surgery by experienced urologists. RFA may be the best option for select patients with significant comorbidity.</p>

ABSTRACT
Objective To present the experience of laparoscopic extraperitoneal radical prostatectomy and evaluate its safety and efficacy. Methods A total of 91 patients diagnosed with localized prostate carcinoma were admitted from February 2003 to June 2008. The level of serum PSA ranged from 7. 5 - 47. 0 ng/ml(mean 14. 0 ng/ml). The volume of the prostate ranged from 35 - 75 ml(mean 52 ml). Biopsy was performed before the operation and the pathological results revealed prostate carcinoma with Gleason score no more than 8. CT, MR and ECT revealed there was no lymph node or seminal vesicle involvement and there was no bone metastasis. The procedures were performed with an-tegrade techniques and pelvic lymphadenectomies were performed in 32 cases and nerve-sparings were performed in 11 cases. Results The operation duration ranged from 105 - 270 min (mean 173 min). Intraoperative blood loss was 110 - 1200 ml(mean 315 ml). Incontinence occurred in 19 cases in early stage and 18 cases recovered within 3 months. Positive surgical margin occurred in 11 cases. There was no complication of urethra stricture during 3 - 30 months' follow-up. No lymph node was involved in 32 cases with pelvic lymphadectomy. Five of the 11 cases received nerve-sparing prostatectomy had normal erectile function during the follow-up. Conclusions Laparoscopic extraperitoneal radical prostatectomy is a safe, effective and efficient surgical procedure with the minimal invasion, less morbidity and rapid recovery. Laparoscopic radical prostatectomy is emerging as an alternative to open radical prostatectomy.
ABSTRACT
Objective To evaluate the technique and efficacy of retroperitoneal laparoscopic partial nephrectomy. Methods From June 2002 to December 2009, 113 cases of renal tumor received retroperitoneal laparoscopic partial nephrectomy. The age ranged from 26 to 73 years. The tumor located in left side in 51 cases and right side in 62 cases with the mean diameter of 3.7 cm(1.2-6.3cm). During the procedure, the renal artery was separated and then clamped with bulldog. The renal parenchymal was incised with cold endoscissor and the tumor was totally removed. Pelvicalyceal repairing and parenchymal hemostasis were then performed. Renal defect closure was achieved with running suture or horizontal mattress suture. Results All the procedures were completed successfully.There was no open conversion. The mean operation time was 85 min(60- 125 min), the mean warm ischemic time was 24 min(19-43 min). The pathology studies revealed 87 cases of clear cell carcinoma, 9 cases of papillary renal cell carcinoma, 7 cases of chromophobe cell carcinoma, 6 cases of perivascular epithelioid renal cell tumor and 4 cases of renal oncocytoma. The surgical margin was negative in all cases. There was no complication of urine leakage. Gross hematuria occurred in 2 cases.During 3-41 months of following up, there was no recurrence. Conclusion Retroperitoneal laparo-scopic partial nephrectomy is safe and effective for the treatment of renal tumor, which becomes an alternative treatment to open procedure.
