PURPOSE:We assessed our experience with urological complications of laparoscopic surgery in regard to incidence, etiology, treatment and possible prevention.MATERIALS AND METHODS:A total of 350 laparoscopic procedures were performed at our institution between June 1993 and December 1999 in 206 men and 139 women. These procedures included pelvic lymph node dissection in 102, bladder neck suspension in 99, adrenalectomy in 54, varicocelectomy in 23, pyeloplasty in 22, nephrectomy in 20, treatment of benign renal pathologies, including cyst, diverticula and calculi, in 13, genitourinary prolapse repair in 11 and miscellaneous procedures in 6 patients. Complications were evaluated according to the procedure attempted and were listed by incidence and etiology.RESULTS:A total of 19 (5.4%) complications occurred in our series. The associated mortality rate was 0.3% and conversion rate was 1.1%. Most intraoperative complications (2.6%) were vascular (4) and visceral injuries (5), while postoperative complications (2.8%) were predominantly thromboembolism (3) and wound infection (2) at trocar sites. The complication rate decreased from 9% for the first 100 to 4% for the subsequent 250 procedures.CONCLUSIONS:Critical documentation of complications of laparoscopic surgery is important for further development of the technique and information for urologists in training. Most of our serious complications should be preventable with better mastery of the different procedural steps. However, laparoscopy must be regarded as major surgery with a significant learning curve.

Objectives. To assess the incidence of the complications in laparoscopic urologic procedures with regard to clinical presentation, etiology, and treatment.Methods. From January 1994 to December 2000, 1085 laparoscopic procedures were performed at three institutions in 1075 patients (702 men, 373 women). A referent surgeon for laparoscopy was at each institution. The major procedures were radical prostatectomy (n = 232), different types of nephrectomy (n = 171) and nephroureterectomy (n = 15), adrenalectomy (n = 130), pyeloplasty (n = 61), pelvic lymph node dissection (n = 130), genitourinary prolapse repair (n = 86), bladder neck suspension (n = 104), and treatment of benign kidney pathologic findings (lithiasis, cysts, and diverticula, n = 55). The complications were listed by incidence and etiology according to the procedure attempted.Results. A total of 75 complications (6.9%) occurred in this multi-institutional series. The mortality rate was 0.09%, and the conversion rate was 2.1%. Vascular (n = 7) and visceral injuries (n = 11) occurred in 24% of complications. Hematomas (n = 10), urinomas (n = 8), and wound infections (n = 7) at the trocar sites were the most frequent postoperative surgical complications. Pulmonary disorders (n = 9) and urinary infections (n = 9) were predominant in the postoperative medical problems.Conclusions. Even though it appears to be minimally invasive, laparoscopy remains major surgery, with serious complications possible. These complications should be preventable with better mastery of the different steps of the procedures. Increased knowledge of the possible complications is essential for urologists in laparoscopic training and may help them improve their learning curve. UROLOGY 58: 899-903, 2001.

OBJECTIVES A multicentre, prospective study (6 private centres, 1 general hospital and 1 teaching hospital) was conducted to evaluate the perioperative morbidity and short-term functional results of the TVT procedure in the treatment of the female urinary stress incontinence. PATIENTS AND METHODS From November 1996 to September 1999, 120 patients with a mean age of 65.2 years (range: 37-91) were operated according to the tension-free vaginal tape (TVT) technique for isolated urinary stress incontinence (stage 2 or 3) in 94 cases and associated with pelvic tone disorder in 26 cases. 59 patients (49.2%) presented recurrence of urinary incontinence that had already been operated between 1 and 4 times. Physical examination demonstrated hypermobility of the urethra in 73 cases (60.8%), isolated clinical sphincter incompetence in 47 cases (39.2%) and pelvic tone disorders in 31 cases. Urodynamic studies, performed in 113 patients, demonstrated sphincter incompetence in 65 cases (57.5%) with a mean maximum urethral closure pressure of 18 cmH2O (range: 5-29). RESULTS The operation, performed under spinal anaesthesia in 97 cases (80.8%), general anaesthesia in 16 cases (13.3%) and local anaesthesia in 7 cases (5.8%) lasted an average of 28.7 min (range: 15-60) for insertion of the TVT. Perioperative complications consisted of twelve bladder injuries (10%) and two pelvic haematomas (1.7%). No cases of infection, erosion or migration of the tape were reported. In the group of 94 patients operated exclusively by TVT, the mean hospital stay was 2.6 days (range: 1-7). Twelve patients (10%) required self-catheterization for 2 to 30 days. With a mean follow-up of 15.2 months (range: 36-6), continence was restored in 104 patients, corresponding to a cure rate of 86.7%. A marked improvement was obtained in 11 cases (9.2%) and five cases (4.2%) were considered to be failures. CONCLUSION The TVT procedure is a new approach to the treatment of female urinary stress incontinence. Its advantages are its simplicity, the rapidity of the technical procedure and the short-term efficacy on continence. A longer follow-up is essential to assess to the functional outcome and the long-term urethral tolerance.
