Pleated colposuspension: Our modification of Burch colposuspension

INTRODUCTION: Burch colposuspension is a standard treatment for stress urinary incontinence. However, it is associated with recurrence and urinary retention. We describe a modification of this technique to overcome these problems and evaluate the results in comparison with the standard procedure. MATERIALS AND METHODS: A total of 145 patients with isolated stress urinary incontinence (SUI), underwent either our modified pleated colposuspension (PC); n = 97) or standard Burch colposuspension (BC) (n = 48). Description of PC: Three No. 0 non-absorbable sutures were placed in the side-to-side manner at the mid-urethral level with 0.5-1.0 cm distance between them using double bites and were passed through the Cooper's ligament. The patients were followed-up every 6 months for SUI and genital prolapse evaluation. Successful surgery was defined as (1) No self-reported SUI symptoms, (2) Negative Marshall's coughing test (MT), (3) No retreatment for SUI, (4) Absence of urodynamic SUI. In addition, failure was defined as the occurrence of urinary retention, use of catheter on 6-week visit, maximum flow rate >15 ml/s, flow time <60 s, or residual urine <100 ml. Data was compared using Student's paired test and Mantel-Haenzel's χ(2) test. P > 0.05 was considered significant. RESULTS: The mean follow-up after surgery for PC was 102.4 months and for BC was 103.6 months. At last follow-up, data suggesting failure (Stress score ≥7, urge score ≥7, Pad test with weight < 15 g/day and positive MT during lithotomic/upright position) were more frequent in BC group (P > 0.05; P > 0.0; P > 0.01; P > 0.05; P > 0.05, respectively). The incidence of recurrent SUI was 5.2% after PC and almost triple (14.6%) after BC. Residual urine <100 ml and weak stream were more frequent in the BC group (P > 0.05; P > 0.01, respectively). Detrusor over-activity on urodynamic studies, Flow time <60 s, urethral pressure profilometry positive for obstruction had a higher incidence in BC group (P > 0.01; P > 0.001; P > 0.01, respectively). CONCLUSION: Our modified pleated colposuspension showed improved outcomes when compared with standard Burch colposuspension.
