Narrow Vagina as a Predictor of Obstructive Voiding Dysfunction after Transobturator Sling Surgery

<b><i>Background:</i></b> Voiding dysfunction (VD) is a potential complication after female midurethral sling operations. <b><i>Objectives:</i></b> Our goal was to assess the rate of obstructive VD after ­transobturator tension-free tape (TOT) procedures and to find perioperative risk factors (RFs) predicting postoperative voiding problems. <b><i>Methods:</i></b> We have retrospectively evaluated the perioperative data of 397 women who underwent TOT operations. Significant post-void residual (PVR) (&#x3e;50 mL) was considered as the primary (objective) end point of the study, the voiding difficulty as the secondary (subjective) 1. First univariate analysis and then multivariate logistic regression were performed, with a 5% significance level. <b><i>Results:</i></b> Significant PVR was present in 51 (12.8%) women; catheterization was needed in 21 (5.3%) and reoperation in 3 (0.8%) cases. Seventy women (17.6%) experienced postoperative voiding difficulty. Narrow vagina (&#x3c;2 cm), older age &#x3e;70 years, and preoperative voiding difficulty were independent RFs for significant PVR (odds ratio: 5.07, 2.14, 5.38, respectively, <i>p</i> &#x3c; 0.05). Preoperative overactive bladder syndrome and previous pelvic organ prolapse surgery were considered independent RFs for postoperative voiding difficulty. <b><i>Conclusions:</i></b> Older age, narrow vagina, or preoperative voiding difficulty increases the chance for significant postoperative PVR. These patients should be chosen and counseled appropriately.

Analysis of Voiding Impairment after Prostate Biopsy and the Effect of Doxazosin Treatment: Outcomes from a Regional Cancer Center

<b><i>Introduction:</i></b> The aim of this study was to investigate the association of transrectal ultrasound (TRUS)-guided prostate biopsy with voiding impairment and the efficacy of doxazosin treatment. <b><i>Methods:</i></b> A prospective observational study including 200 male patients undergoing TRUS-guided prostate biopsy was performed between May 2020 and December 2020. One hundred patients underwent biopsy with doxazosin (doxazosin group). The remaining 100 patients underwent biopsy without doxazosin (control group). All patients were questioned regarding post-biopsy voiding difficulty and acute urinary retention. The International Prostate Symptom Score (IPSS), maximal urinary flow rate (Q_max), and residual urine volume were recorded before biopsy and at 7 and 30 days after biopsy. <b><i>Results:</i></b> There were no significant differences in baseline parameters between the two groups. The rate of post-biopsy voiding difficulty in the doxazosin group was significantly lower than that in the control group. Compared with baseline values, doxazosin treatment significantly improved IPSS, quality of life scores, and Q_max after biopsy (<i>p</i> &#x3c; 0.05). The baseline values of IPSS and prostate size may be risk factors for post-biopsy voiding difficulty. <b><i>Conclusion:</i></b> TRUS-guided prostate biopsy causes transient voiding impairments, which may be improved by doxazosin treatment.

Laparoscopic T-Plasty for the Treatment of Refractory Bladder Neck Stenosis

Preliminary results of a case series on refractory bladder neck stenosis treated with laparoscopic T-plasty are presented in this article. This study retrospectively identified nine patients with refractory bladder neck stenosis aged 60 to 80 years between May 2016 and December 2017, who had undergone laparoscopic T-plasty. All patients presented voiding difficulty and failed after two or more prior endoscopic treatments. Laparoscopic T-plasty was performed by incising the anterior wall of the bladder neck in a T-shaped manner and creating two well-vascularized and tension-free flaps, which offer the possibility to reconstruct a wide bladder neck. After a mean follow-up of 14.7 months (ranging 3–22 months), a successful outcome was achieved in eight patients without incontinence secondary to surgery. Recurrent voiding difficulty developed in one patient, which was cured after a following endoscopic treatment. Through these nine patients, a preliminary conclusion can be drawn that a wider bladder neck can be obtained through modified YV-reconstruction of the bladder neck, while avoiding external urethral sphincter injury. And laparoscopic T-plasty has clear advantages compared with an open approach. It is an available and effective option for refractory bladder neck stenosis.

Evaluation of per-operative cough stress test during transobturator mid-urethral sling surgery

Purpose: Currently, it is unclear how the mesh tension should be adjusted on the transobturator tape surgery (TOT) for improving continence. The aim of this study was to evaluate the effects of per-operative cough stress test on TOT. Materials and methods: Between March 2007 and December 2011, 206 women with SUI were enrolled in this study. Patients were randomly categorized to treatment with TOT (96) or TOT with cough stress test (110). The IIQ-7 and the UDI-6 were used to identify satisfaction level. At the end of 1st year, two groups were compared patient characteristics, operation time, duration of hospital stay, cure and complication rates. Results: The cure rate was 84.37% 81/96) versus 83.63% (92/110) in TOT and TOT with cough test groups, respectively. Postoperatively ten patient (10/110, 9.09%) suffered voiding difficulties (> 250 ml residual urine) in TOT with cough stress test group. Five patients were discharged with transurethral catheter, whereas, in traditional TOT group, two patients (2/96, 2.1%) had transient postoperative voiding difficulty and two patients were treated with repeated catheterization for 1 week (p < 0.05). Postoperative groin pain was present in 7/96 (8%) versus 24/110 (22%) in TOT and TOT with cough test groups, respectively (p < 0.05). TOT with cough stress test group had an higher rate of complications like, retention of urine, necessitating to cut the tape, mesh erosion and pain in groin or leg. No patient had resistant voiding difficulty or prolonged urinary retention (> 1 week) in traditional TOT group. Conclusions: We believe that per-operative cough stress test leads to overtreatment of stress urinary incontinence when the complication rates were considered.

Outcome of buccal mucosa urethroplasty in the management of urethral strictures

Objective: The objective of the study is to report the outcome of buccal mucosal urethroplasty. Materials and methods: The follow up data of 15 patients undergoing single stage urethroplasty from September 2010 to September 2015 were retropectively reviewed. They received buccal mucosa graft for urethroplasty. The patients were followed for complications and outcome. Results: Mean age was 53.7 ± 13.6 The stricture length ranged from 3 to 6 cm (mean 4.4 ± 0.8). The success rate for buccal mucosa urethroplasty (BMU) was 67.7% at 12th month. Three patients presenting with voiding difficulty in the 3rd month and one in the next 12 months, had urethral restenosis. One patient had fistula formation at 6th month postoperatively. Five patients underwent retreatment procedures such as internal urethrotomy, urethroplasty and/or internal urethrotomy. Conclusions: The buccal mucosa is easy to obtain and handle, therefore BMU can be safely and effectively managed outside high volume institutions.
