Clinical analysis of female urethral diverticulum resection and reconstruction under Jacknife position / 中华泌尿外科杂志

ABSTRACT

Objective To explore the clinical efficacy of female urethral diverticulum resection and reconstruction under the folding position.Methods Retrospective analysis of 22 female patients with urethral diverticulum was performed from September 2010 to December 2018.There were 12 cases of simple diverticulum,6 cases of horseshoe diverticulum,4 cases of circumferential diverticulum,aged from 26 to 72 years,with an average of 46.2 years,whose BMI ranged from 24.2 to 34.8 kg/m2,with an average of 30.4 kg/m2.Eleven cases (50％) presented with dysuria,10 cases (45.5％) with repeated urinary tract infections,7 cases (31.2％) with difficulty of voiding,10 cases (45.5％) with urethral secretion,9 cases (40.1％) with difficulty of sexual intercourse,and 4 cases (18.2％) without symptoms.Unlike the traditional surgical procedure under the lithotomy position,the folding position was used to expose the vagina and separate the vaginal mucosa by longitudinal incision,and the diverticulum was completely removed to the neck.The peri-operative complications and efficacy were recorded.Results All 22 cases underwent successful procedures,and were followed up for 25.2 months on average (ranged 8 to 42 months).One of them suffered from weak stream 2 months after operation,with residual urine volume of 100ml by ultrasonography.Her symptoms improved after dilatation of the urethra.Two cases suffered from different degrees of lower urinary tract storage symptoms 1 month after the operation (1 case of mild dysuria and 1 case of urinary tract infection),who improved after oral administration of levofloxacin tablets for 3-5 days.All patients had no urethral diverticulum recurrence 3 months later by ultrasonography,half a year by cystoscopy,and every six months by ultrasonography.Conclusions Surgical treatment is still the best choice for patients with urethral diverticulum.The success rate of transvaginal urethral diverticulum reconstruction with a Jackknife position is high,postoperative recurrence rate is low,and postoperative complications are few.
