“…42,43 In 2007, an S-shaped coaxial dilator was developed to follow the normal urethral contour. 44 Most cases require multiple dilations and a period of selfdilation as single dilations have less favorable outcomes. 13,28,34,42 Ramchandani and colleagues described a transurethral balloon dilation technique with regional anesthesia.…”

Postprostatectomy vesicourethral anastomotic stenosis (VUAS) remains a challenging problem for both patient and urologist. Improved surgical techniques and perioperative identification and treatment of risk factors has led to a decline over the last several decades. High-level evidence to guide management is lacking, primarily relying on small retrospective studies and expert opinion. Endourologic therapies, including dilation and transurethral incision or resection with or without adjunct injection of scar modulators is considered first-line management. Recalcitrant VUAS requires surgical reconstruction of the vesicourethral anastomosis, and in poor surgical candidates, a chronic indwelling catheter or urinary diversion may be the only option. This review provides an update in the diagnosis and management of postprostatectomy VUAS.

“…Especially when the stricture occurs early after RP, the initial step is usually urethral dilation. There are multiple options available for dilation including sounds, filiforms and followers, coaxial dilators [39], and balloon dilators [40]. The success of dilation in the absence of RT ranges from 40 to 90 % [32,41,42].…”

The Devastated Bladder Outlet in Cancer Survivors After Local Therapy for Prostate Cancer

Prostate cancer is common; this combined with the long life expectancy after treatment has sparked a growing emphasis on prostate cancer survivorship care. An important goal of such care is preserving quality of life through ameliorating the side effects of therapy. Posterior urethral stenosis (PUS) can occur as a complication of radical prostatectomy (RP) and radiation therapy (RT). Evaluation includes a history, physical exam, uroflowmetry, lab tests, cystoscopy, and radiological studies. PUS is initially managed with endoscopic techniques such as dilation or internal urethrotomy. Patients who fail such therapies can be offered surgical reconstruction. Continence is an important factor in the management of PUS. In some cases, particularly after radiotherapy, the outlet may not be salvageable, and a permanent indwelling catheter or urinary diversion may be the only options. We review the evaluation of patients with the devastated bladder outlet: those undergoing repeat endoscopic treatments, surgical reconstruction, or urinary diversion.

“…To further improve this process, single-use S-shaped dilators with hydrophilic coating were shaped like the normal male urethra to permit smooth advancement proximally [16]. The researchers and inventors qualify that the use and efficacy of these dilators are limited by the density and length of the stricture disease.…”

“…A urethral catheter was left indwelling for 3-6 weeks. Of the 17 patients who were followed for 20 months (range, [14][15][16][17][18][19][20][21][22][23][24][25][26][27], two required repeat dilation or OIU/DVIU for stricture recurrence and four patients had complications of fever, transient incontinence, urinary extravasation, and acute epididymitis. Olschewski et al [32] reported experience with high-dose-rate (HDR) brachytherapy with iridium-192 in 10 men with strictures.…”

“…A urethral catheter was left indwelling for 1 week. Of the 10 patients followed for a mean of 14.8 months (range, [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27], two required repeat OIU/DVIU for stricture recurrence with one subsequently requiring open urethroplasty. Like the small series reported by Sun et al [31], the results were not reported according to stricture location, stricture etiology, or other defining characteristics, except for length, making interpretation of the results very problematic.…”
