Management of 18 Difficult Vesicovaginal and Urethrovaginal Fistulas with Modified Ingelman-Sundberg and Martius Operations

Our experience in the management of difficult vesicovaginal and urethrovaginal fistulas is presented. The fistulas were secondary to radiation damage and extensive local fibrosis owing to previous attempts to repair surgically. Satisfactory surgical repair of the fistulas was obtained by interposition of viable gracilis muscle and labial fibrofatty tissue at the repair site. The patients have been followed for 1 to 2 years postoperatively.

Evaluation of Anterior Extra Vesical Ureteroneocystostomy in Kidney Transplantation

We evaluated the anterior extravesical ureteroneocystostomy technique in 184 consecutive renal transplants done in 2 consecutive calendar years. Complications included 5 cases of ureteral and 1 of pelvic necrosis, and 2 of ureteral obstruction, with a ureteral complication rate of less than 4 per cent. All cases of pelvic or ureteral necrosis except 1 were seen in cadaver donor kidneys that were imported from other centers. No bladder complications were seen. Pelvioureteral obstruction, presumably of congenital origin in the cadaver donor, was discovered in the kidney after transplantation in 2 cases and was corrected successfully by pyeloureterostomy to the native ureter. The extraordinary simplicity of this technique, coupled with improvement in the complication rate, makes it our procedure of choice.

Correction of adult penile curvature with a Nesbit operation

Nesbits technique of excising ellipses of tunica albuginea has been effective in correcting chordee in children. We have used this technique successfully in adults for the correction of 19 congenital and traumatic curvatures, as well as those resulting from stable Peyronies disease. All patients retained potency and reported excellent correction of the deformities. We believe that Nesbits operation is the procedure of choice for the correction of disabling adult penile curvature.

Radiation-treated carcinoma of prostate. Comparison of survival of black and white patients by Gleason's grading system.

The survival of 117 black and white patients treated by radiation for carcinoma of the prostate at SUNY Health Science Center at Brooklyn (SUNY/HSCB) and Kings County Hospital Center (KCHC) was analyzed according to Gleasons grading system. The effect of total pattern score and its relationship to stage and survival and to race were intercompared. In both black and white racial groups, there was strong correlation between high pattern score and high stage p = <001. The percentage of black patients presenting with high pattern score (7–10) was significantly greater, 43 versus 27%; this adversely affected stage and survival. The median survival for white and black patients was 4.8 and 3.2 years, respectively; p = 0.007. Stage for stage and grade for grade, survival was similar in both racial groups.

Transverse Ureteral Advancement Technique of Ureteroneocystostomy (Cohen Reimplant) and a Modification for Difficult Cases (Experience with 121 Ureters)

We reimplanted 121 ureters by the Cohen technique. A modification is introduced for difficult cases, making the Cohen technique more adaptable for dilated ureters and small bladders. Radiographic studies obtained at least 6 months after reimplantation revealed only 1 case of persistent reflux (grade I), no case of contralateral reflux and no obstruction. Even though the series included 35 ureters with grade V primary reflux and 7 primary obstructive megaureters, only 7 ureters were tapered. This finding suggests that the Cohen method might require tapering in a smaller percentage of cases compared to other reimplantation techniques.

Percutaneous management of retroperitoneal abscesses

Retroperitoneal abscesses have been a difficult diagnostic and therapeutic challenge in the past. With the advent of precise noninvasive imaging modalities, they now are defined more easily. Percutaneous guided catheter drainage has changed our therapeutic approach to this disease and enabled rapid and complete drainage to be performed in the majority of cases. Although the literature is replete with documentation of the percutaneous management of intra-abdominal abscesses, series dealing with retroperitoneal abscesses exclusively are surprisingly infrequent. We report on the percutaneous treatment of 31 retroperitoneal abscesses and the combined percutaneous and surgical management of 4 additional cases.

Scintiscan for acute intrascrotal conditions.

The efficacy and merit of testicular imaging, utilizing Tc-99m pertechnetate, were studied prospectively in a group of patients who presented with acute onset of scrotal pain. Consecutive admissions were studied. All were managed according to the likelihood of the problem being testicular torsion, which was determined from the clinical history, physical examination and the routine laboratory data. The final diagnostic outcome, whether by surgical exploration or clinical progress with conservative treatment, is collated with the preoperative scintigraphic interpretations, made with respect to predefined criteria. Analysis of the pretreatment images obtained in 57 patients shows that the radionuclide study is highly reliable in cases of testicular torsion and epididymo-orchitis. It appears to be much less dependable, however, in the other acute scrotal conditions. Torsions that are intermittent in nature or corrected manually apparently can have variable presentations. Certain difficulties and potential pitfalls encountered in interpreting the scintigraphic studies are discussed.

Initial experience with therasonic lithotriptor

Piezoelectric shock wave lithotripsy has been shown to offer a low-cost, safe, anesthesia-free yet effective means of disintegrating urinary calculi. The Therasonic lithotriptor combines proprietary piezoelectric shock wave technology for effective stone fragmentation with a multi-purpose urologic table and both fluoroscopic and ultrasound imaging for accurate stone localization and real-time treatment monitoring. From December 1, 1988 to November 15, 1989, 138 patients with 172 calculi were treated (94.2% were intrarenal, 5.8% were in ureter). All stones greater than or equal to 4 mm were considered suitable for treatment. Lithotripsy was performed under intravenous sedation except when ancillary procedures were necessary. For evaluation of device effectiveness, 94 patients were available with follow-up greater than or equal to thirty days. Successful fragmentation (stone free or residual debris less than or equal to 4 mm) was achieved in 97 percent of patients. The retreatment rate for stones 0.5-2.0 cm was 11 percent, and the overall retreatment rate was 21.2 percent regardless of stone size. Complications were minimal, transient, and resolved spontaneously.

A Urologist’s Viewpoint: Treatment of Invasive Bladder Cancer by the XRT/5FU Protocol

Primary transitional cell carcinoma (TCC) localized to the urinary bladder occurs as: A, carcinoma in situ (CIS), B, superficial disease penetrating the basement membrane but not invasive of detrusor muscle, C, disease invasive of the detrusor muscle, or a mixture of these. CIS is most frequently treated with intravesical chemo or immunotherapy. Radical cystectomy is utilized for treatment failures. Superficial disease is treated by transurethral resection (TUR-BT) followed by intravesical chemo or immunotherapy.

Bilateral kidney herniation Complication of cutaneous pyelostomy

A case of bilateral kidney herniation through cutaneous pyelostomy stomas is reported. The child is doing well after successful closure of the pyelostomies and repair of both ureteropelvic junctions obstructions.
