ABSTRACT
Objective To evaluate if strategic urethrostomy could reduce complications in complicated hypospadias repair.Methods From January 2016 to August 2018,165 patients of complicated hypospadias were reviewed according to inclusion criteria.They were divided into three groups of one-stage repair (group A,n =86),two-stage repair using Bracka procedure (group B,n =49) and strategic urethrostomy (group C,n =30).The median age was 26 months in group A,24 months in group B and 28 months in group C.The median length of urethral defect was 3.0 (2.0-10.0) cm,4.0 (2.5-10.0) cm and 3.8(2.5-11.0) cm in the different three groups,respectively.No difference showed in age or length of urethral defect among 3 groups.Three groups were compared with rates of urethral fistula,urethral stricture and urethral diverticulum.Results After average of 20.0 months follow-up,the urethral stricture incidence of group C [3.3％ (1/30)] was significantly lower than that of group A [22.0％ (19/86),P =0.023] and group B[24.5％ (12/49),P =0.032].The complications were found in 7 patients with urethral fistula and 11 patients with urethral diverticulum in group A,4 patients with urethral fistula and 3 patients with urethral diverticulum in group B,none patient with urethral fistula nor urethral diverticulum in group C,respectively.The incidence of urethral fistula was 8.1％ (7/86),8.2％ (4/49) and 0 in the three groups,and the rate of urethral diverticulum was 12.8％ (11/86),6.1％ (3/49) and 0,respectively.None difference was shown neither in the incidence of urethral fistula nor urethral diverticulum among the three groups(P ＞ 0.05).Conclusions Strategic urethrostomy is a novel and effective method for complicated hypospadias repair.Application of strategic urethrostomy can significantly decrease urethral stricture and improve success rate in complicated hypospadias repair.
ABSTRACT
Objective To evaluate the complications and long-term efficacy of inside-out transobturator transvaginal tape ( TVT-O) for the treatment of stress urinary incontinence ( SUI) .Methods From January 2008 to December 2013,236 consecutive female patients (mean age 56 ±9 years,range 44-88 years)with the symptom of incontinence when abdominal pressure increasing (such as walking), underwent TVT-O operation.All these patients needed pads and were diagnosed with SUI by cough test and Marshall -bonny test before surgery , with the mean international consultation committee on incontinence questionnaire short form ( ICI-Q-SF) score of 15.6 ±3.9.Two grouping methods were used:the mid-term group including patients whose follow-up time was between 6 months and 3 years, the long-term group including patients whose follow-up time >3 years,the group of patients who underwent TVT-O only and the group of patients who underwent TVT-O plus pelvic floor repair at the same time . Their clinical and follow-up data , intraoperative and postoperative complications , subjective and objective effects were recorded and analyzed.Results Of these 236 patients,there were 1 case of bladder perforation (0.4%) and 1 case of intraoperative sling exposure to vagina ( 0.4%) .Postoperative complications included 36 ( 19.1%) groin/puncture point pain ,18 (9.5%) de novo frequency of micturition ,8 (4.2%) urinary retention /difficulty of urination.All the complications were relieved after symptomatic treatment or surgery except 2 cases of urinary retention/difficulty of urination.Their symptom kept existing after urethral dilatation and sling dissection and long-term intermittent self-catheterization was needed .One hundred and eighty-nine patients completed more than six months of follow-up, with mean follow-up time of ( 35.0 ±12.5 ) months.One hundred and sixteen (61.4%) cases was arranged to mid-term group and 73(38.6%) was arranged to long-term group.88.9%patients ( 168/189 ) were cured objectively and 9.5% patients ( 18/189 ) improved. There was also a significant subjective improvement ( ICI-Q-SF scores:15.6 ±3.9 preoperative versus 6.7 ± 2.3 postoperative,P0.05 ) . Patients who underwent TVT-O and those who underwent TVT-O +pelvic floor repair had no significant difference in efficacy (cured +improved rate 97.8%versus 100.0%,P>0.05).Conclusion TVT-O is a safe,effective and durable treatment for SUI , whether or not with concomitant procedure of pelvic floor repairment.
