New Frontier

The first report in Literature dealing with an endourethral prosthesis in the treatment of recurrent bulbar strictures dates back to 1988. Since then other prostheses with different design and materials have been proposed. The Urolume by A.M.S., the first ever, is used worldwide and its indications are better known due to a longer follow-up time. In 6 months epithelium covers the prosthesis and it is generally well tolerated, but some Authors do not agree with its use in the treatment of traumatic strictures. Titanium prostheses have been used in few cases. A temporary steel alloy prosthesis, the Urocoil, has been proposed recently. Not enough follow-up data are available about this and the new “thermic memory” prosthesis. The bigdegradable prosthesis, used till now only on rabbits, actually represents the new frontier in the treatment of urethral strictures.

This study aims to determine the role of the Ombudsman of the Republic of Indonesia in North Sumatra Representative in the Supervision of Population and Civil Registry Service in Medan City. This study uses a qualitative approach with descriptive methods describing information about the data obtained from the field in the form of written and oral data from the parties studied. Data is collected based on interviews and documentation. The results of this study indicate that the role of the Ombudsman of the Republic of Indonesia in North Sumatra was carried out in the form of external supervision. External supervision is supervision carried out by the Ombudsman of the Republic of Indonesia Representative of North Sumatra to the Medan Population and Civil Registry Service. Actions taken in the supervision process are incoming reports, follow-up of the first report and follow-up of the report. Based on the research that has been carried out, it has been concluded that the role of the Ombudsman of the Republic of Indonesia in the North Sumatra Representative in supervising the service provider of the Population and Civil Registry services is carried out in the form of external supervision. In supervising the handling of public reports of alleged poor service in the area of population administration, it has been effective, with several efforts to handle reports such as: (1) Clarification; (2) Investigation; (3) Recommendations; (4) Monitoring.

Free Skin Graft

The Authors report their experience in the new urethroplasty technique by Barbagli for penile and bulbar urethral strictures. This procedure involves a free skin graft sutured to the corpora cavernosa. With this dorsal approach mechanical weakening is virtually impossible, so pseudo-diverticulum or urethrocele cannot develop. We adopted this technique in 5 patients during the last 12 months. The strictures of the urethra were 2.5 to 8 cm long. The follow-up, even thought short, show that this technique is safe and quite simple.

Lotus Petal Flap

Introduction: Perineal urethrostomy is a valuable technique in the management of complex anterior urethral strictures, as well as following penectomy or urethrectomy. Traditional techniques that employ perineal or scrotal skin flaps have documented failure rates of up to 30%. Current techniques for salvage have only modest success, leaving patients few options other than permanent suprapubic catheter or cystectomy and ileal conduit formation.Results: We present a new method of perineal urethrostomy using perforator-based lotus petal flaps in cases which were high risk or unsuitable for traditional perineal urethrostomy techniques, or where traditional strategies had failed. All patients demonstrated continent voiding at a minimum of 22 months follow-up, with patency confirmed by flexible cystoscopy. No complications were encountered.Conclusion: Utilisation of lotus petal flaps in high-risk cases of perineal urethrostomy will lead to significant improvements in patient outcomes. The availability of larger amounts of soft tissue coverage will obviate the need for compromise on either resection of involved urethra, or calibre and inset of urethrostomy. This will subsequently minimise the rates of failure, reduce the requirement for urinary diversion procedures and lead to improved quality of life.

Congenital urethral strictures are well recognised in human beings and have recently been described in two cats but have not been previously reported in dogs. A 10-month-old female English Bull Terrier presented with a life-long history of being unable to pass a normal stream of urine. Urethrocystoscopy confirmed the presence of a stricture lesion in the proximal urethra. This thin, membranous structure was effaced under endoscopic visualisation using a 10 mm diameter balloon-dilation catheter. Complete and sustained resolution of clinical signs occurred after a single dilation procedure. To the best of our knowledge, this is the first report of a congenital urethral stricture in a dog and the term congenital obstructive proximal urethral membrane may be useful for describing these lesions in the future.

Objectives: Balanitis xerotica obliterans (BXO) related strictures involving the external urethral meatus. We reviewed our result with the use of circular mucosal graft in the reconstruction of strictures. Methods: Between March 1997 and January 2012, 15 patients underwent circular buccal mucosal urethroplasy for BXO related anterior urethral strictures. Urethral catheter was removed within 2 weeks. Follow-up included patient symptoms assessment, cosmetic outcome and uroflowmetry. Results: Median follow-up was 20.5 months (range 4 to 96). Mean postoperative peak urinary flow rate obtained 1 month after catheter removal was 22.4 ml per second. All patients had a normal meatus and none had recurrent stricture, chordee or erectile dysfunction. A functional and cosmetic outcome was achieved in 100% of the patients. Conclusions: Circular mucosal graft technique for treatment of meatal strictures is an efficient method for the restoration of a functional and cosmetic penis.

Sigma-rectum pouch (Mainz Pouch II) operation, which is a detubularized modification of the well-known ureterosigmoidostomy is becoming a popular alternative of urinary diversion in selected patients. 12 male patients underwent this operation due to locally invasive bladder tumours or incurable urethral strictures and fistulas. The pouch was tailored using 12 cm of sigmoid colon and rectum and performing a side to side anastomosis of the detubularized bowel in an inverted U shape. The new formed pouch was fixed onto the posterior peritoneum so that traction affecting the pouch was minimized. Postoperative radiological analysis revealed no obstruction or ureteral reflux. Urodynamic studies revealed low pressure, high volume reservoirs. Only 1 patient had reservoir wall contractions of low amplitude during filling. Although early postoperative blood chemistry did not reveal any metabolic abnormality, at long-term follow-up some patients showed important electrolyte and acid-base disorders.

We present our experience with a simplified anastomotic posterior urethroplasty to highlight the necessity and usefulness of ancillary reconstructive maneuvers. We reviewed the records of 46 patients who had undergone anastomotic repair of posterior urethral strictures due to pelvic trauma between 2000 and 2007. Mean patient age at surgery was 43 years. Average stricture length was 2.3 cm. Repair was performed with a progressive perineal anastomotic procedure using flexible cystoscope by means of transcystostomic approach: after mobilization of the bulbo-membranous urethra and the corporal splitting, the prostatic apex is well visualized and the membranous urethra is sectioned proximally; the flexible cystoscope by means of transcystostomic approach facilitates to find the proximal urethral lumen and to perform the bulbo-prostatic anastomosis. Mean follow-up was 32 months. Of 46 cases, 40 (87 %) were successful and 6 (13 %) failed with recurrence of the stricture. Urinary incontinence did not develop in any patients. The operative details and maneuvers facilitate the preparation of the bulbo-membranous urethral tract and prostatic apex, and simplify the performance of the anastomotic repair.
