RESUMO
Objective To evaluate the effect and safety of a modified Prolift procedure, without preceding partial trachelectomy or hysterectomy for pelvic organ prolapse (POP) with coexistent cervical elongation. Methods Clinical data of 72 patients that underwent a modified Prolift procedure for POP with coexistent cervical elongation, between December 2008 and June 2012 in Fuzhou General Hospital of Nanjing Military Command was retrospectively analysed. A comparison was carried out between preoperative and postoperative parameters of pelvic organ prolapse quantitation system (POP-Q), and an objective evaluation was made according to the overall cure rate and recurrence rate. Pelvic floor distress inventory-short form 20 (PFDI-20) was used to investigate the subjective cure rate and improvement of symptoms. Results Patients were followed up at median 52 months (36-78 months). One bladder perforation and one rectum perforation occurred during the procedure. Four patients (6%, 4/72) had uterine prolapse at 9-19 months after the opertaion and had transvaginal hysterectomy laterly. The overall anatomical correction rate was 94%(68/72). Six patients (8%, 6/72) had mesh exposures at 3-9 months after the opertaion. Scores of PFDI-20 decreased sifnificantly after the procedure (118.2±25.2 vs 12.1±8.0 vs 12.5±9.5 vs 13.0±9.9, P<0.05). The patients′ satisfaction rate was 92% (66/72). Conclusion This modified Prolift procedure, without preceding partial trachelectomy or hysterectomy, could effectively and safely correct POP with coexistent cervical elongation.
RESUMO
Objective To analyze the risk factors of voiding dysfunction after mid-urethral sling surgery for stress urinary incontinence.Methods Clinical data of 573 consecutive patients undergoing midurethral sling surgery from January 2003 to December 2010 were collected and analyzed retrospectively.All relative risk factors were evaluated by univariate and multivariate Logistic analysis to identify risk factors of voiding dysfunction.Results Voiding dysfunction occurred in 28 patients,with an incidence of 4.9％ (28/573).Univariate analysis showed that age,previous pelvic surgery,pre-operative postvoid residuals,maximum flow rate,average urine flow rate,Valsalva leak point pressure,concomitant anterior pelvic repair and operator performing＜50 procedures were the relative risk factors (P＜0.05) for voiding dysfunction.Multivariate logistic regression analysis revealed that the maximum flow rate (Qmax) ≤ 15 ml/s (OR=3.782,P=0.003) was an independent risk factor for voiding dysfunction and surgery experience was its protection factors (OR=0.295,P=0.016).Conclusions Qmax ≤ 15 ml/s on preoperative urodynamic study is an independent risk factor for voiding dysfunction after mid-urethral sling procedure.Improving skill of surgery and strengthening technical training will help to reduce the incidence of this complication.
