Trans-obturator vaginal tape (TOT) for female stress incontinence: one year follow-up in 120 patients.

OBJECTIVES: The aim of this study was to evaluate the effectiveness of a new minimally invasive surgical procedure, the Trans-obturator Vaginal Tape (TOT) in the treatment of female urodynamic stress incontinence (USI) and to analyse functional results and quality of life after one year of follow up. MATERIAL AND METHOD: 120 consecutive women with stress urinary incontinence underwent the procedure since February 2002 under general or loco-regional anesthesia. Minimum follow up was one year (range 12-30 months). Mean age was 58 years (range 31-86). 70% of the patients had pure USI. 5 patients were previously operated for USI. In 10 cases, concomitant repair of pelvic floor defects was mandatory. Collection of the data included operative time, pre- and post-operative complications. Patients were post-operatively assessed at one week, one month and one year. A validated urinary incontinence-specific measure of Quality of Life (QoL) questionnaire (Contilife) was sent and completed 12 months after surgery. RESULTS: The mean operative time was 12 min (range 6-30) with a catheterisation time of 0,9 day (range 0-2). No severe bleeding was observed. There were 13 minor lateral tears of the vagina without any sequelae. Three perforations of the urethra and one of the bladder occurred during the learning phase. In two cases a re-intervention was necessary for tape removal when the injury was not recognised during the procedure. Two transient urinary retention needed a supra pubic catheter and tape release. Eleven women presented transient voiding outflow obstruction. After one month, 93% patients were cured with no pad and a negative cough test with a full bladder. Uroflowmetry did not show any significant changes between pre- and post-operative time in all the population. De novo urgency occurred only in 2.5% and persistent dysuria (Qmax <10 ml/s and/or post-void residual volume >120 cc) in 4%. 80% of patients were completely dry after one year and 12% were greatly improved. According to the pre-operative maximal urethral closure pressure, continence rate was 86% above 30 cm H2O and 76% below 30 cm H2O respectively. Global satisfaction of women at 1 year was 78% with good scores based on daily and effort activities, self-image, emotional and sexual activities. CONCLUSIONS: TOT is a safe and effective new minimal invasive procedure for USI with a low rate of complications. To confirm the success of TOT, longer follow up in large population is mandatory to assess the reliability of this attractive technique.

A simple maneuver to replace dislodged laparoscopic port.

Inadvertent dislodgment of laparoscopic port can occur despite preventive measures. We describe a simple maneuver to replace a dislodged port using a palpation probe. The principle is analogous to that of using a laparoscopic grasping forceps. It is easy to perform, quick, reliable, safe, and particularly useful for the laparoscopists in training.

[Laparoscopy in urology].

Since the past 10 years, results have established laparoscopy's efficacy. It is actually a consistent surgical option for a lot of indications met in urology. The rational behind performing laparoscopic procedures includes shorter hospital stays, less postoperative pain and a more rapid return to usual activity. Drawbacks of laparoscopy include significant learning curve, longer operative times and higher overall costs. One particular focus is the oncologic applications of laparoscopy for nephrectomy and specially for radical prostatectomy. Laparoscopy become nowadays an usual part of the armamenturium of urological teams.

[The urology department].

The Department of Urology of Erasme Hspital, University of Brussels, has participated to the development and implementation of new technologies that have significantly transformed the specialty in the last 25 years. The minimally invasive treatment of benign prostatic hypertrophia was developed by the use of Trans-Urethral Needle Ablation (TUNA) and new pharmacological treatments. Treatment of urinary stones by extracorporeal shockwaves lithotripsy and Endourology has allowed to avoid operating hundred of patients each year. In the field of prostate cancer, an original laparoscopic prostatectomy technique by the extraperitoneal approach was developed in our unit. The prevention of prostate cancer and the influence of various nutritional factors and its early diagnosis by the use of different markers have been the subject of numerous publications and have contributed to improve our knowledge in this field. Different prognostic factors of bladder cancer have been evaluated and in particular their place with the use of intravesical BCG. A better understanding of the different mechanisms involved in erectile dysfunction has been the subject of numerous studies during the last 20 years and the department is internationally recognised as a reference centre in this field.

Extraperitoneal laparoscopic radical prostatectomy. Results after 50 cases.

INTRODUCTION: After an initial experience using transperitoneal laparoscopic radical prostatectomy as described by Vallancien and Guillonneau, we developed a pure extraperitoneal approach. This approach seems more comparable to the open technique and avoid potential risks of specific complications due to the transperitoneal approach. We evaluated the perioperative parameters (blood loss, operating time, transfusion rate) and postoperative results (oncological results, continence and potency) after our first 50 cases. MATERIAL AND METHOD: Between September 1999 and September 2000, we performed 50 laparoscopic radical prostatectomy. On average, patients were 63.3 years old (range 47-71), had preoperative mean PSA values of 9.14 ng/ml (1.1-23). Median Gleason score was 6 (4-10) with 2.5 (1-6) positive biopsies for a mean prostate volume of 40 cm(3) (17.5-95.0). Clinical stage was T1, T2a, T2b and T3 in 46.3, 41.5, 9.8 and 2.4% of the cases, respectively. We used a pure extraperitoneal approach and we performed a descending technique starting with the dissection at the bladder neck. The seminal vesicles dissection is comparable to the open approach. RESULTS: 42 extraperitoneal and 8 transperitoneal procedures were performed (2 in the initial experience, 3 because of previous abdominal surgery and 3 because of incidental peritoneal opening). Mean operative time was 317 min, mean blood loss 680 cm(3), transfusion rate of 13%. 1 patient/50 was converted to an open procedure. Pathological stage was pT1a, pT2a, pT2b, pT2c, pT3a and pT3b in 2.2, 8.5, 42.5, 2.2, 34 and 10.6% of cases, respectively. Positive surgical margins were observed in 22% of cases. The potency rate after neurovascular bilateral bundle preservation was 43% at 3 months (n = 7) and 67% at 6 months and (n = 6) without any further treatment. The continence rate (no pad) was 39% at 3 months and 85% at 6 months. Detectable postoperative PSA at 3 month was observed in 2 patients only. Two major complications occurred: one acute transient renal failure one uretrorectal fistula at day 20. CONCLUSIONS: The extraperitoneal laparoscopic radical prostatectomy results seem comparable to transperitoneal laparoscopic radical prostatectomy or open surgery. This approach is reproducible and seems to avoid the potential risks of intraperitoneal injury. Long-term follow up and comparative series are however necessary to further evaluate these new techniques.
