A prospective study of pelvic floor dysfunctions related to delivery.

OBJECTIVE: To estimate the prevalence and impact on quality of life of urinary incontinence (UI) and anal incontinence (AI) three months after first delivery; to identify risk factors involved in UI or AI; to evaluate possible changes in sexual behaviour and anatomical modifications of pelvic floor after childbirth. STUDY DESIGN: A multicenter prospective study, in six Italian Ob/Gyn departments, of nulliparous women who delivered at term (37-42 weeks of gestation) between April and September 2005. A structured questionnaire investigated several maternal and obstetric variables. UI and AI were assessed by administration of the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and according to Wexner's Continence Grading Scale, at 2-3 days post-partum and at 3 months after delivery. Changes in sexual behaviour, and pelvic floor condition after delivery, were also recorded. Statistical analysis included comparison of means (Mann-Whitney or Student's t-test) and proportions (Chi-square test). Multiple logistic regression analysis was performed including variables that were significant in univariate comparisons. RESULTS: Of 960 enrolled women, 744 were evaluated 3 months after delivery and included in final analysis. The prevalences of UI and AI at that time were 21.6% and 16.3%, respectively. Onset of incontinence during pregnancy was an independent predictor for persistent UI (Odds Ratio (OR) 4.6, Confidence Interval (CI) 3.1-6.8, p<0.001) and AI (OR 3.6, CI 2.2-6.1, p<0.001). Family history of urinary or anal incontinence were respectively associated with UI (OR 2.6, CI 1.6-4.0, p<0.001) and AI (OR 2.4, CI 1.4-4.0, p<0.001) 3 months after delivery. Among obstetric factors, vaginal delivery was a strong risk factor for UI (OR 3.3, CI 2.0-5.3, p<0.001). The sexual score improved 3 months after delivery in 72.4% of women. Urogynaecological evaluation showed a significant association between grade 1-2 anterior prolapse, urethral hypermobility and UI. CONCLUSION: New onset of UI or AI during pregnancy, positive family history and vaginal delivery are independent risk factors for the persistence of symptoms of UI and AI in the early postpartum period. Adequate counselling and the implementation of targeted strategies to prevent or early identify these conditions are therefore mandatory to improve the patient's quality of life.

Peri-operative morbidity and early results of a randomised trial comparing TVT and TVT-O.

The aim of this study was to compare the morbidity and short-term efficacy of retro-pubic (TVT) and inside-out trans-obturator (TVT-O) sub-urethral sling in the treatment of stress urinary incontinence. This was a prospective multi-centre randomised trial; 231 women with primary stress urinary incontinence were randomised to TVT (114) or TVT-O (117). The International Consultation on Incontinence-Short Form (ICIQ-SF), Women Irritative Prostate Symptoms Score (W-IPSS) and Patient Global Impression of Severity (PGI-S) questionnaires were used to evaluate the impact of incontinence and voiding dysfunction on QoL and to measure the patient's perception of incontinence severity. The primary and secondary outcome measures were rates of success and complications. The SPSS software was used for data analysis. The TVT-O procedure was associated with significantly shorter operation time and with a more extensive use of general anaesthesia when compared with TVT. There were 5 (4%) bladder perforations in the TVT group compared with none in the TVT-O group. Rates of early post-operative urinary retention and voiding difficulty were similar for both groups and no difference was found in the average hospital stay. Six patients (5%) in the TVT-O group complained of thigh pain in the post-operative course. The median follow-up time was 6 months. Two hundred eighteen patients were available for the analysis of outcomes. Subjective and objective cure rates were 92% and 92% in the TVT group and 87% and 89% in the TVT-O group. The ICIQ-SF questionnaire symptoms score showed a highly statistical decrease in both groups, the W-IPSS on the contrary was unchanged. Our data show that both procedures were equally effective in the short-term for the treatment of stress urinary incontinence with a highly significant improvement in incontinence-related QoL.

Surgical approach to urinary endometriosis: experience on 28 cases.

OBJECTIVES: Endometriosis (e.) involving the urinary tract must be regarded as a rare condition with specific surgical implications. Our experience on the treatment of 28 patients is presented. PATIENTS AND METHODS: Twenty-eight patients with a urological e. (bladder 11 patients, ureter 14, both bladder and ureter 3) were observed and treated between 1995 and 2005. Thirteen patients (46%) had been previously surgically treated for pelvic e. at a mean distance of 22 months before. All the patients with bladder e. presented with typical symptoms related to menses and the urinary location was isolated in 42.8%. Differently, the patients having ureteral involvement complained often a vague or silent symptomatology, but they always showed some extra-urinary pelvic locations. Among the cases with bladder e., 2 patients underwent TUR and hormonal therapy and 12 partial cystectomy. The patients with ureteral e. were submitted to ureterolysis in 5 cases, segmentary ureterectomy and uretero-ureteroanastomosis in 2 and terminal ureterectomy and ureterocystoneostomy in 8. Two more cases with ureteral e. were nephrectomized due to end-stage renal atrophy. RESULTS: At a mean distance of 58 months (9-110 months) from surgery, 22 patients have a unremarkable follow-up. On the other hand, an urological relapse was evidenced in 5 cases previously submitted to TUR (2 cases), ureterolysis (2 cases) or segmentary ureterectomy and termino-terminal ureteral anastomosis (1 case). The relapsing e. was treated by partial cystectomy or terminal ureterectomy with ureterocystoneostomy, with good results over time. CONCLUSION: Urinary tract is rarely involved by e., but this condition has peculiar clinical and surgical implications. Being TUR ineffective, the therapy of choice of bladder e. is partial cystectomy, possibly via a laparoscopic approach. Differently from bladder e., the preoperative diagnosis of ureteral e. is surely hard. So, a high index of suspect should be regarded in each young female patient with a ureteral stricture and a study of the upper urinary tract (US and/or urography) should be performed in all the patients with pelvic e. Ureterolysis can be successful only in a minority of the cases showing a very limited disease not determining any urinary flow obstructions. In all the other cases the procedure of choice is terminal ureterectomy and ureterocystoneostomy without employing the distal ureter.

Clinical aspects and surgical treatment of urinary tract endometriosis: our experience with 31 cases.

OBJECTIVES: To present and discuss clinical and surgical management of urologic endometriosis. METHODS: Retrospective review of a database on surgical patients with endometriosis. RESULTS: Thirty-one patients (incidence, 2.6%; mean age, 33.1 yr) were affected by urologic endometriosis (bladder, 12; ureter, 15; both, 4). Bladder endometriosis was revealed by symptoms related to menses and showed a typical endoscopic picture, whereas ureteral involvement had a nonspecific or silent symptomatology. All patients affected by bladder endometriosis and undergoing transurethral resection (2 cases) developed a bladder recurrence; a ureteral recurrence was observed in two of six patients submitted to laparoscopic ureterolysis and in one of two patients submitted to ureterectomy with ureteroureterostomy. Conversely, no relapses were observed among the 14 patients who had partial cystectomy or the 9 who had ureterectomy and ureterocystoneostomy. Finally, two patients underwent nephrectomy due to end-stage renal atrophy. CONCLUSIONS: Cystoscopy is advisable in women with pelvic endometriosis with lower urinary tract symptoms; the upper urinary tract should be evaluated in all patients with pelvic endometriosis to exclude asymptomatic ureteral involvement. Partial cystectomy gives the best results when used to treat bladder endometriosis. Ureterolysis can be successful only in case of limited ureteral involvement with no urinary obstruction, whereas terminal ureterectomy and ureterocystoneostomy should be preferred in case of obstructive ureteral endometriosis.

Surgical treatment of ureteral obstruction from endometriosis: our experience with thirteen cases.

Endometriosis is a biologically benign albeit aggressive pathology marked by high local recurrences. Ureteral involvement accounts for only a minority of cases (0.1-0.4%) with often non-specific symptoms at clinical presentation and difficult preoperative diagnosis. Thirteen cases of severe ureteral endometriosis (i.e. causing significant obstruction to the urinary flow) were observed and surgically treated, out of 17 ureteral units affected (three cases of bilateral involvement, one case of complete pyeloureteral duplicity). The initial symptomatology was acute and related to ureteral obstruction in eight cases, silent and non-specific in the other five; a presumptive diagnosis was made only for the seven patients (53.9%) with a positive medical history for pelvic (and in two cases also ureteral) endometriosis. Preoperative drainage of urine proved necessary for eight patients due to the complete functional exclusion of the excretory axis. One patient (7.7%) underwent nephrectomy due to renal atrophy. Segmental ureteral resection and termino-terminal anastomosis were performed in two patients, while seven patients underwent segmental ureterectomy and ureterocystoneostomy, with bladder psoas hitching in four cases and vesical flap according to Casati-Boari in one case. All three cases of bilateral involvement were treated by bilateral segmental ureterectomy and trans-uretero-uretero-cystoneostomy with bladder psoas hitching. Following histological examination, all patients were diagnosed with active ureteral endometriosis, which was found to be intrinsic in five cases (38.5%) and extrinsic in the other eight. One of the two patients that had undergone ureterectomy and termino-terminal anastomosis had to undergo ureteral resection and ureterocystoneostomy 22 months later due to relapsing endometriosis-induced stenosis. Conversely, no ureteral endometriosis relapses occurred in the remaining 12 patients within the mean follow-up time of 41.1 months (range 6-91). Ureteral endometriosis is marked by non-specific symptoms, making preoperative diagnosis often difficult. Therefore, an ultrasound or urographic examination of the urinary tract in case of pelvic endometriosis is absolutely essential. In our experience, terminal ureterectomy with ureterocystoneostomy has provided long-term favourable results as extended ureteral resection can be performed and continuity of the urinary tract can be restored without resorting to the distal pelvic ureter, which is often affected by the disease besides being more subject to relapses.
