Comparative StudyQuality of life after cystectomy and orthotopic neobladder versus ileal conduit urinary diversion.
The impact of bladder removal and urinary diversion for patients' everyday life is largely unknown. The aims of this study were to compare subjective morbidity of ileal neobladder to the urethra versus ileal conduit urinary diversion and to elucidate its influence on quality of life. A total of 102 patients who underwent cystectomy due to a bladder malignancy were included in the study. ⋯ Only 1.5% of neobladder patients had wet clothes caused by urine leakage during the day, versus 48.5% of ileal conduit patients. Moreover, 97% of our neobladder patients would recommend the same urinary diversion to a friend suffering from the same disease, but only 36% of ileal conduit patients would do so. These results demonstrate that the quality of life is preserved to a higher degree after orthotopic neobladder than after ileal conduit urinary diversion.

Traumatic injuries to the penis and testicles are uncommon, likely due to the well-protected location and degree of mobility of these organs. Because of this the management of these injuries has historically been controversial. However, current literature supports immediate evaluation and surgical repair of these traumatic injuries to prevent complications such as erectile dysfunction or testicular loss. Herein the diagnostic and therapeutic options for both traumatic penile fracture and testicular rupture are reviewed with emphasis on immediate evaluation and repair.

Effect of renal pelvic distension on the ureteropelvic and ureterovesical junctions and the urinary bladder: the renal pelvivesical reflex.
For investigation of the effect of distension of the renal pelvis on the ureteropelvic (UPJ) and ureterovesical junctions (UVJ) and on the urinary bladder, nephrostomy was performed on 14 anesthetized mongrel dogs. The pressure was measured in the UPJ by a catheter with a side port introduced through the nephrostomy and in the UVJ and urinary bladder by two catheters inserted cystoscopically. Likewise, a balloon mounted on the tip of a catheter was introduced into the renal pelvis. ⋯ This process is supported by a vesical pressure drop. The opening of the UPJ together with the UVJ and the vesical relaxation observed on renal pelvic distension seem to be reflex in nature. A "renal pelvivesical reflex" is postulated to regulate the flow of urine from the renal pelvis to the urinary bladder, preventing the occurrence of urine collection in, or backflow into, the renal pelvis or the ureter.

ReviewContemporary criteria for cadaveric organ donation in renal transplantation: the need for better selection parameters.
A major problem facing transplantation is the disparity between the availability of cadaver donors and the number of recipients awaiting transplantation. Efforts to deal with this issue have involved the use of "marginal donors." Results obtained using these organs have often been significantly worse at 1 and 3 years of follow-up. The problem of how to select and utilize these donors is of critical importance to both patients and society. ⋯ Although these appear adequate for predicting the results for the ideal donor, they are not adequate for assessing results for marginal donors. New criteria are of critical importance for better utilization of these organs. The purpose of this review is to examine the current criteria for ideal and marginal donors, review the critical issues to be clarified, and discuss options for improvement results in the future.

Abnormal ultrasonic pattern in contralateral testes in patients with unilateral testicular cancer.
Ultrasound examination and biopsy of the nonaffected testis was performed in 78 men with a unilateral testicular cancer. Each testis was measured in three planes and the volume was calculated using the formula of an ellipsoid. The ultrasonic texture of each testis was given a score ranging from 1 to 5 as follows: 1, very regular; 2, slightly irregular; 3, irregular with small echogenic points; 4, very irregular or with coarse echogenic points; and 5, irregular with demarcated areas raising suspicion of tumor. ⋯ In all, 9 testes contained CIS tubules, and 8 of these were given score 4; 1 testis with CIS in only 5% of the tubules was given score 3. The predictive value of score 4 for the testis to contain CIS was 22.2%, and the predictive value of a score different from 4 that the testis would not contain CIS was 97.6%. We conclude that a large percentage of contralateral testes in men with unilateral testicular cancer have an abnormal echotexture and that CIS is most likely found in testes given score 4 by ultrasound.
