Bladder neck contracture and urethral stricture as complications of renal transplantation

Calculus formation in renal transplant patients

Of 149 renal transplants performed between May 1965 and December 1980 a stapled ureteroureterostomy was done in 112 (75 per cent) using a commercially available stapling device. Calculus developed in 7 patients (6.3 per cent) in whom this technique was used, with the interval between transplantation and calculus formation being 13 months to 6 years. We conclude that the stapled ureteroureterostomy should be reserved for special instances, such as a short donor ureter or when the correction of urological complications demands a rapid ureteroureterostomy.

Kidney stones and renal transplantation

Only 10 cases of renal calculi in transplanted kidneys are reported in the literature. Etiology is not uniform in all the cases. Some of these cases were managed conservatively. We herein report a case in which the etiology of the stone may be urinary tract infection. This patient was managed conservatively.

Incidence of vesicle neck contracture complicating prostatic resection in hemodialysis patients

Four hemodialysis patients with no or minimal urine output underwent transurethral resection of the prostate. Bladder neck contractures developed postoperatively in all 4 cases. A review of the literature demonstrated no emphasis on the relatively high incidence of this complication in hemodialysis patients. A discussion of the possible etiology, diagnosis and therapeutic modalities is presented.

Urethral strictures: treatment with intralesional steroids

A review of steroid management of urethral strictures is presented. The 96 patients were followed for a year or more after urethral injection with triamcinolone. Intralesional steroid may be used in many types of strictures but it is especially useful in those cases with strictures in the distal urethra or the meatus, those occurring after radical prostatectomy and in some cases when 1 or more urethroplasties have been done. Every practicing urologist can benefit from using stricture injection in selected cases.
