A review of the past twenty months of intestinal-urinary diversion with use of the single J urinary diversion stents at Albany Medical Center Hospital and the Albany Veterans Administration Medical Center resulted in no ureteroileal anastomotic fistulas. Thirty-seven stented anastomoses were performed in 19 patients.

Insertion of either a semirigid or inflatable penile prosthesis at the completion of surgery for various malignancies was performed. Twelve men had implants and were followed at least one year with excellent results. Careful preoperative sexual counseling with the patient's spouse is recommended and adds immeasureably to the mental well-being of the patient in the postoperative period. Penile prostheses can be placed easily after radical cystectomy, radical prostatectomy (perineal or retropubic), urethrectomy, and bilateral orchiectomy. Penile prosthesis placement may also be recommended for patients with less than adequate erectile function who may be undergoing pelvic lymphadenectomy with 125I implantation for prostatic carcinoma.
Chlamydia trachomatis and Ureaplasma urealyticum have been implicated as causative organisms in infections involving the male and female urogenital tracts. Seminal fluid, anterior urethral swabs and first-voided urine specimens from men undergoing infertility evaluation, with and without pyosemia, or anterior urethritis were cultured for Chlamydia trachomatis and Ureaplasma urealyticum. The method used to isolate Chlamydia trachomatis involved cytochalasin-B treated McCoy cells, and NYC and A7 solid media were used for the isolation of Ureaplasma urealyticum. Isolation of Chlamydia trachomatis from seminal fluid has not been possible even in the face of pyosemia and the presence of Chlamydia trachomatis in urine and urethral swab material. The reasons for the inability to culture Chlamydia trachomatis will be explored.

During a 4-year period 7 patients with priapism were managed successfully with a non-incision treatment program. Three were treated by hypotensive anesthesia with sodium nitroprusside, 2 by the Winter procedure (creating a temporary cavernospongiosum shunt) and 2 by combining hypotensive anesthesia and the Winter procedure. Causes of the priapism were pelvic infection in 1 patient, sickle cell trait in 2 and post-hemodialysis in 2. The cause was not known in 2 cases. Of the 7 patients 5 were potent before the onset of the priapism and remained so after treatment. No complications of therapy were noted and hospitalization averaged 1.4 days, with 5 patients being discharged the day after treatment. Our experience with these 7 patients indicates that creation of a vascular shunt by an operative technique may not be necessary to alleviate priapism.

Congenital curvature of the penile shaft without hypospadias is a rare problem that poses cosmetic and functional disability. It is caused by disparate growth of the penile corpora. Surgical repair of 7 cases is reviewed, with follow-up of two to eight years. The results of these 7 cases are added to 13 other cases reported previously. The Nesbit technique was used with the modification of (1) preserving the dorsal neurovascular bundle to avoid anesthesia and lymphedema of the glans in selected cases, and (2) intraoperative use of saline-induced erections and Allis clamp " tucks" of the tunica albuginea to insure a satisfactory repair.
We report a case of rupture of the bladder. The 2 precipitating causes for the rupture appeared to be the diuretic and obtunding effect of alcohol combined with the bladder neck constriction caused by the alpha-sympathomimetic drug, methamphetamine.
Retrograde pyelography to demonstrate the renal pelvis and ureters is a common urologic procedure. Newer contrast materials and better radiographic techniques have obviated many of the previous indications for retrograde studies were independently reviewed by two urologists and a radiologist to determine if the studies were indicated, appropriately timed, informative, and complete. Our results indicate a high percentage of these examinations are incompletely performed and uninformative and could have been replaced by noninvasive studies. What constitutes a complete retrograde study and when to utilize this examination is discussed.
A survey is made of the 20-year experience with more than 300 living donors in renal transplantation at the Peter Bent Brigham Hospital. Details are given pertaining to the first transplantation of the kidney from one living person to another in December 1954. The surgical technique, the complications and the results of renal transplantation from a living donor are summarized. The philosophic and psychologic problems encountered are described. A comparison of results summarized by Murray of living, related donor transplants to cadaveric donor transplants is included. This paper constitutes a salute to the familial living donor.
In a four-year period 500 outpatient vasectomies were performed by the author. Bilateral scrotal incisions were used in all cases as were metal clips to occlude the vas deferens. Operating time rarely exceeded fifteen minutes. No failures and no sperm granulomas were encountered. Complications were rare and included a single scrotal hematoma and six minor infections. Unilateral absence of the vas deferens was noted in 2 patients. The technique to be described is a simple, complication-free method of vasectomy.
Concepts of renal counterbalance and animal experiments have long supported nephrectomy for prolonged complete unilateral ureteral obstruction. The situation in humans has been clarified by only a few reported cases. Herein we report 3 cases with relief of obstruction after at least 28, 28 and 150 days. Evidence is presented to support renal preservation in similar cases.
The efficacy of ultrasonography in the diagnosis of renal masses in our own series and in the recent literature has been reviewed. Ultrasonography in combination with cyst puncture approaches 100 per cent accuracy in the diagnosis of lesions more than 3 cm. in diameter that can be adequately delineated. Complications appear to be minimal.
A case of a bladder fistula following total hip replacement is attributable to thermal injury by self-curing polymethylmethacrylate projecting into the retropubic space.
