Urethroplasty with Lingual Mucosal Graft for Management of Long and Recurrent Strictures of the Anterior Urethra


Background: Currently, there is renewed controversy over which tissues and techniques are optimal for urethral replacement. Because surgical treatment of urethral stricture diseases is an evolving process, new technical refinements are continuously being suggested.

Objectives: To evaluate the efficacy and mid-term results of using lingual mucosal grafts (LMG) in management of long and recurrent strictures of the anterior urethra.

Patients and Methods: The study included 18 patients with long recurrent strictures of the anterior urethra. The recurrence arose in 14 patients after several visual internal urethrotomies, after hypospadias repair in 2, and after buccal mucosal graft (BMG) urethroplasty in 2. The strictures varied in length from 3 to 9 cm. Dorsal onlay of the LMGs was used in 12 patients, while ventral onlay was used in 6 patients. Follow-up lasted from 3 to 24 months. Postoperatively, all patients were followed by urethrography, uroflowmetry, and urethroscopy. Successful reconstruction criteria were a peak flow rate greater than 15 ml/sec and no need for postoperative dilatation.

Results: Out of 18 cases, 15 were successful (83.3%). Of the 3 failures, 1 patient had an urethrocutaneous fistula, and 2 patients developed recurrence in the stricture 3 months after urethroplasty.

Conclusion: The technique of substitution urethroplasty using lingual mucosal grafts has been shown to be easy, safe, and reproducible with good surgical and functional outcomes. The success rate is comparable to other techniques of substitution urethroplasty, especially BMGs, but with fewer donor site complications. Our mid-term results are satisfactory, but larger comparative studies with longer duration of follow-up are needed to confirm the durability of these results.

Bilateral Native Nephrectomy: Before or After Renal Transplantation?


Objectives: We hypothesized that patients undergoing bilateral native nephrectomy have a better perioperative course and earlier recovery when renal transplantation is performed before nephrectomy rather than afterwards, since the anuric state is avoided.

Methods: Of 9 patients undergoing bilateral nephrectomy between November 2000 and December 2005, 5 had nephrectomy before renal transplant and 4 had nephrectomy after transplant. Hospital course and complications within 3 months of each operation were compared.

Results: Patients who underwent bilateral nephrectomy prior to transplantation spent more days in the hospital overall (mean = 25 days) than did patients who received their transplant before nephrectomy (mean = 14 days). Serum creatinine levels over the course of both operations were greater for the group maintained on dialysis, but both groups had similar values at the time of discharge from the second procedure and at 1-year follow-up. Major and minor complications were more frequent in those who underwent nephrectomy before transplant.

Conclusion: The order of operations for patients undergoing both bilateral nephrectomy and renal transplantation impacts perioperative course, especially in the first 3 months after the operations are completed. Bilateral native nephrectomy before renal transplantation is associated with a greater risk of complications and longer overall duration of hospitalization.
