AMS 3-piece inflatable penile prosthesis implantation in men with Peyronie's disease: comparison of CX and Ultrex cylinders.
PURPOSE: We compared the ability of the CX and Ultrex cylinders to straighten the penis in men who received a 3-piece AMS 700 series inflatable penile prosthesis for erectile dysfunction and erectile deformity due to Peyronie's disease. MATERIALS AND METHODS: The records of 34 and 38 patients receiving devices CX and Ultrex cylinders, respectively, were reviewed. RESULTS: All 34 patients receiving the CX cylinders achieved complete penile straightening with cylinder inflation and bending alone. In 10 of 38 patients receiving the Ultrex cylinders complete straightening with cylinder inflation and bending could not be achieved, and simultaneous corporoplasty was necessary. CONCLUSIONS: Girth expanding CX cylinders have better penile straightening properties than girth and length expanding Ultrex cylinders. We recommend use of CX cylinders for 3-piece AMS 700 series inflatable penile prosthesis implantation in men with Peyronie's disease.

Primary erectile dysfunction in a man with congenital isolation of the corpora cavernosa.
We report on a 33-year-old man with primary erectile dysfunction, isolated cavernous bodies, corporeal veno-occlusive dysfunction, and hypoplastic cavernous arteries. To our knowledge, this is only the second reported case of absence of communication between the corpora cavernosa.

Cultures from genitourinary prostheses at reoperation: questioning the role of Staphylococcus epidermidis in periprosthetic infection.
PURPOSE: We determine the colony counts of organisms present on culture of clinically uninfected genitourinary prostheses at reoperation for reasons other than infection. These results served as control data for comparison with cultures from infected devices to determine the relative incidence of organisms involved. MATERIALS AND METHODS: Cultures were prospectively obtained from 65 penile prostheses and 22 artificial urinary sphincters. Patients were followed for a minimum of 12 months after reoperation or until development of infection (mean 27 months) at which time cultures were again obtained. RESULTS: Low colony counts of Staphylococcus epidermidis were isolated from 40% of uninfected penile prostheses and 36% of artificial urinary sphincters. Only 3 of these devices later became infected (9%) and in all cases a higher colony count of another organism was found at explanation. CONCLUSIONS: While Staph. epidermidis can cause prosthesis infection, low colony counts of the organism may not be associated with clinical infection. Therefore, the high incidence of infection attributed to this organism may be overestimated.

Renal cell carcinoma arising in a regressed multicystic dysplastic kidney.
Controversy surrounds the management of multicystic dysplastic kidney. Recent advances in radiological imaging have resulted in a higher incidence of its detection, and they provide an accurate noninvasive means of diagnosis and followup. Consequently, the need for surgical removal of these lesions is being reevaluated. We report a case of renal cell carcinoma arising from solid renal dysplasia associated with a regressed multicystic dysplastic kidney. We emphasize the potential risk of nonoperative management of these lesions and further define the spectrum of malignant degeneration associated with renal dysplasia.

Complications of the exaggerated lithotomy position: a review of 177 cases.
To examine the incidence and nature of complications associated with placing patients in the exaggerated lithotomy position, a retrospective review of 177 procedures requiring the use of that position was done. Factors analyzed were patient age, height, weight and time in position. Height-to-weight ratio was calculated in an effort to establish a relationship between body habitus and common peroneal nerve neurapraxia, the most common complication (15.8%) noted in the study. Statistical analysis failed to show any relationship between these factors and the incidence of neurapraxic complications. The study demonstrates the safety of this highly useful surgical position for perineal operations. The technical points relative to positioning are emphasized.

Complex urethral reconstruction.
Modern tissue transfer techniques, often incorporating penile or scrotal skin islands based on a dartos fascia pedicle, have revolutionized urethral reconstruction. There are certain situations, however, that require a more creative and complex approach. The majority of these cases involve patients with panurethral stricture disease or those who have undergone multiple previous procedures for urethral stricture disease or hypospadias and their subsequent complications. In this article, the authors discuss the various aspects of these two conditions and outline several techniques for urethral reconstruction in these challenging patients.

Preoperative evaluation of erectile function with dynamic infusion cavernosometry/cavernosography in patients undergoing surgery for Peyronie's disease: correlation with postoperative results.
Most reports of surgical therapy for Peyronie's disease to date have not included detailed preoperative assessment of erectile function. To evaluate the relationship between preoperative erectile function and postoperative success, we reviewed 25 consecutive patients with Peyronie's disease who underwent surgery and evaluation with dynamic infusion cavernosometry and cavernosography preoperatively. Overall results of dynamic infusion cavernosometry and cavernosography revealed corporeal veno-occlusive dysfunction in 76% of the patients and inadequate arterial inflow parameters in 44%. Among 20 patients treated with plaque excision and dermal graft inlay, adequate postoperative erectile function for satisfactory intercourse occurred in 4 of 4 (100%) with an equilibrium accumulated intracorporeal pressure of greater than or equal to 70 mm. Hg, 9 of 12 (75%) with an equilibrium accumulated intracorporeal pressure of 40 to 65 mm. Hg and 1 of 4 (25%) with an equilibrium accumulated intracorporeal pressure of less than 35 mm. Hg. These data may be helpful to counsel patients before surgical therapy, and may explain some of the disparate results previously reported after plaque excision and dermal graft inlay on the basis of patient selection.

Penile venous ligation in 18 patients with 1 to 3 years of followup.
We report the results of penile venous ligation in 18 consecutive patients with erectile insufficiency due to corporeal venous occlusive dysfunction. Patient age ranged from 25 to 65 years (mean 47). Duration of erectile dysfunction ranged from 9 to 468 months (mean 95) and followup ranged from 12 to 37 months (mean 24). Of 18 patients 11 (61%) have sufficient persistent improvement in erections to permit unaided coitus. Of 7 failures 6 had temporary improvement in erections after the procedure: in 5 the improvement lasted 6 months or less, while only 1 had lasting improvement (24 months) before relapse. Reports of results of penile venous ligation should not include patients who have been followed for less than 12 months. Longer followup is needed before results of penile venous ligation beyond 2 years are known.

Hypertension as a complication of multicystic dysplastic kidney.
The detection of multicystic dysplastic kidney in utero using prenatal ultrasound is becoming a more frequent occurrence. An accurate diagnosis of multicystic dysplastic kidney usually can be made radiographically, and therefore the main indication for surgery in the asymptomatic patient may be the potential risk of complications developing later in life. We report hypertension as a complication of multicystic dysplastic kidney and review the literature.

Resection of nonrenal retroperitoneal tumors with large vena caval thrombi using cardiopulmonary bypass and hypothermic circulatory arrest.
Cardiopulmonary bypass with deep hypothermic circulatory arrest is a useful adjunct in the operative management of renal cell carcinoma associated with large vena caval thrombi. We present 2 patients with nonrenal retroperitoneal tumors and extensive vena caval thrombi who underwent successful surgical treatment with this method. The primary tumor was a leiomyosarcoma of the vena cava in 1 patient and a pheochromocytoma with hepatic invasion in 1. Cardiopulmonary bypass with deep hypothermic circulatory arrest is effective in decreasing the operative risk and improving the feasibility of resection in complex surgical cases. Consideration should be given to its use in a wider range of indicated procedures.

Nephron-sparing surgery for renal cell carcinoma with venous involvement.
A nephron-sparing operation recently has been shown to provide extended survival free of disease in selected patients with localized renal cell carcinoma, particularly for tumors of lower stage. To define better the role of conservative surgical treatment in more locally advanced renal cell carcinoma we reviewed 9 patients with venous tumor involvement in solitary functioning kidneys who underwent a nephron-sparing operation. Complete tumor resection with adequate preservation of renal function was accomplished in all cases. Of the 9 patients 5 had no evidence of disease 7 to 93 months (mean 33.2 months) postoperatively. The remaining 4 patients died of metastatic renal cell carcinoma 17 to 47 months (mean 35.5 months) postoperatively, 2 of whom had concomitant local recurrences in the renal remnant. Based on previously reported results of total nephrectomy for renal cell carcinoma with venous involvement and the morbidity associated with renal replacement therapy, we believe that a nephron-sparing operation is a viable option in the management of these patients.

Perioperative complications of adrenal surgery.
Complications of adrenal surgery may be medical or surgical. The latter are related to the operative approach as well as to the type and extent of the adrenal lesion and are in general similar to those seen in other open procedures. The medical complications include adrenal insufficiency as a result of bilateral adrenalectomy or continuing contralateral suppression, as well as more specific problems resulting from the physiological derangements of Cushing's syndrome, pheochromocytoma, and primary aldosteronism. Nevertheless, with meticulous preoperative management and postoperative care, adrenal surgery can be performed with low morbidity and mortality rates.
