Optilume® drug-coated balloon dilation in complex female urethral stricture.

The treatment of female urethral stricture disease is in flux in terms of developing guidelines for surgical treatment. Urethral strictures in women are rare, but frequently result because of urethral instrumentation or surgery. Stricture sites vary from proximal, intrasphincteric, distal or at the meatus. Stricture formation after previous urethral surgery may pose a special challenge. We describe the first Optilume® urethral drug-coated balloon dilation for female urethral stricture disease involving the sphincter. After six months follow-up the patient remains stricture free with full continence and complete bladder emptying.

Female urethral avulsion and bladder neck closure: What now? Trigonal tubularization with placement of an artificial urinary sphincter.

Bladder neck closure after severe polytrauma with an absent urethra poses a huge challenge for a young woman wanting to urinate normally. Considerations are reconstruction of a neourethra and operative means to gain continence. We describe a case of trigonal tubularization to function as a neourethra, together with the implantation of an artificial urinary sphincter. Eleven years after suffering from an open book pelvic rim fracture at 18 years, successful reconstruction of a trigonal neourethra enabled continence and residual-free spontaneous voiding at 29 years.

Salvage perineal-retropubic AUS cuff in paraplegic patient with exstrophy-epispadias complex after previous cuff erosion at bladder neck.

Cuff erosion at the bladder neck of an implanted artificial urinary sphincter (AUS) needs complete explantation of the device. The subsequent scar tissues predispose to repeated cuff erosion, when another AUS is implanted with the cuff at a similar location. We describe a paraplegic patient with exstrophy-epispadias complex that suffered from an AUS cuff erosion at the bladder neck. We use a novel perineal-retropubic route for cuff placement, with preparation similar to a retropubic male sling. At 12 years follow-up the AUS is still functional and the patient continent.

Urethro-cavernosal-spongiosal fistula after intralesional mitomycin C for recurrent urethral stricture disease.

Intralesional mitomycin C after direct visual internal urethrotomy for recurrent urethral stricture disease in patients suboptimal for open urethroplasty is an established option. We report a case of urethro-cavernosal-spongiosal fistula after intralesional mitomycin C into an area of previous dorsal inlay urethroplasty. The patient presented with pus draining from the urethral meatus ten days after treatment. Sterile abscesses developed within the corporal and spongious bodies, draining freely into the urethra. Complete spontaneous healing followed short-term transurethral catheterization and antibiotic prophylaxis.

World record: Single AMS 800 artificial urinary sphincter functioning uninterrupted for 29 years in male paraplegic patient.

Lapides has revolutionized the treatment of neurogenic patients by introducing routine intermittent catheterization in 1971. This drastically lowered mortality from urosepsis. Scott introduced the artificial urinary sphincter (AUS) in 1972. This gave a completely new perspective for incontinent patients by dramatically increasing the quality of life. In patients with neurogenic urinary incontinence, the principles of care are preserving renal function, maintaining a low-pressure reservoir, allowing unobstructed urine flow and providing continence. We describe a male patient that received an AUS with a bladder neck cuff that functioned without revision for 29 years. After 30 years, AUS exchange proved successful.

Excessive fibrosis and non-function after ATOMS (adjustable transobturator male system): A case of capsular contracture?

The adjustable transobturator male system (ATOMS) treats post-prostatectomy urinary incontinence by compression of the proximal bulbous urethra. It reminds of the Kaufman prosthesis described in 1978. We describe a case where an excessive fibrotic reaction occurred around the cushion. Furthermore, the bulbous urethra underneath, developed severe atrophy devoid of any visible blood supply. We suspect ongoing shear forces around the cushion while sitting resulting in a chain reaction of acute through chronic inflammation and progressive fibrosis and encapsulation. Does the encapsulation lead to capsular contracture resulting in non-function?

Intrapelvic bulboprostatic repair after urethral distraction injury and failed bulbomembranous anastomosis.

A failed end-to-end anastomosis after membranous urethral distraction injury post-trauma is a surgical challenge. We present a case of a young man after complex pelvic injury. Revision urethroplasty was done utilizing nerve and vessel sparing techniques. Intrasphincteric dissection enabled bulbous urethral pull-through with intrapelvic anastomosis with good success. Low dose tadalafil was given to optimize penile rehabilitation.

Preservation of erectile function by artery sparing dilation of the corpora cavernosa in prolonged priapism.

Prolonged low-flow priapism causes structural impotence. We describe a case where potency has been preserved by off-centre corporal dilation to spare the cavernosal arteries. The patient suffered from idiopathic priapism lasting more than 72 hours before presentation. Corporoglanular shunts were performed thrice over a period of six days, twice also performing off-centre corporal dilation along the inside of the tunica. The idea was not to damage the central cavernosal arteries. Corporal blood supply spontaneously improved. Successful intercourse was possible after six months. Artery sparing cavernosal dilation techniques might improve spontaneous recovery in select cases.

Evaluation of Mathisen's technique for ureteral reimplantation in children with primary vesicoureteral reflux.

INTRODUCTION: Although cross-trigonal ureteral reimplantation (Cohen) is a commonly used technique in children, it represents a non-physiological transfer of the ureteral orifices and may prove challenging with regard to endoscopic ureteral operations in later life. In 1964, Mathisen described an alternative method of ureteral reimplantation with lateralization of the neohiatus, creating an orthotopic course of the submucosal ureter. We have evaluated success and complication rates of both techniques that were applied sequentially at our departments. METHODS: Forty-eight consecutive patients (83 ureters, 24 males/24 females) following Mathisen reimplantation were compared with 53 consecutive patients (98 ureters, 30 males/23 females) following Cohen reimplantation. Inclusion criteria were primary vesicoureteral reflux (VUR) and no previous intervention. Reflux grades (Mathisen 58 ureters/69.9% VUR ≥ III; Cohen 66 ureters/66.7% VUR ≥ III) and the occurence of other complicating factors (ureteroceles, megaureters, posterior urethral valves) in both groups were comparable. RESULTS: After Cohen's reimplantation there were no immediate complications requiring intervention; during follow-up (mean 28.2 months) three patients (5.6%) suffered febrile urinary tract infections (UTIs), of which one (1.8%) was diagnosed with a persisting VUR. Persistent hydronephroses (≥II SFU) were recorded in six patients (13.2%). After reimplantation using Mathisen's technique, two patients (4.1%) suffered significant intravesical bleeding; during follow-up (mean 23.06 months) four patients (8.3%) suffered febrile UTIs, and seven patients (14.5%) were diagnosed with persisting VUR after a mean follow-up of 10.8 months. The patients with persistent VUR had more commonly high-grade (IV and V) VUR initially, compared to the whole group. Two patients (4.1%) had persistent hydronephroses (≥II SFU). Mathisen's technique for ureteral reimplantation yielded a significantly (p = 0.0256 patients, p = 0.006 ureterorenal units) lower success rate (85.5% patients, 89.2% ureterorenal units) in comparison with Cohen's technique (98.2% patients, 99% ureterorenal units). Although there was no intervention for obstruction, persistent hydronephrosis was more common in the Cohen group (13.2% vs. 4.1%, n.s.). CONCLUSIONS: Despite the advantages of an orthotopic ureteral orifice close to the bladder neck, as achieved by Mathisen's reimplantation, cross-trigonal ureteral reimplantation proved more reliable for VUR correction. As regards optimizing the results, patient selection for either technique could prove essential. Nevertheless, as regards the difficulties with ectopic ureteral orifices in the Cohen technique in the long-term follow-up, the concept of anatomic, orthotopic ureteral reimplantation should be pursued and the technique should be further refined.
