PURPOSE: We investigated whether the AMS Ultrex cylinder, developed to provide cylinder lengthening while controlling girth expansion, acted as a tissue expander and, thus, promoted penile lengthening. MATERIALS AND METHODS: Between December 1990 and January 1992, 59 AMS Ultrex prostheses were implanted. Cylinder length corresponded to intracorporeal measurements. The results of lengthening and occurrence of an S-shaped deformity were statistically analyzed. RESULTS: No penile lengthening occurred. In 19 patients (32%) cylinder replacement was required for the S-shaped deformity. CONCLUSIONS: Ultrex cylinders should be downsized and prolonged inflation should be avoided. They should not be implanted in cases of Peyronie's disease, or to replace malleable or self-contained inflatable implants.

The object of this study was to determine whether the immunohistochemical detection of cytokeratin (CK)-positive cells is useful as quick section diagnosis, and whether the retroperitoneal lymphadenectomy (RLA) can be reduced by this method without any disadvantage for the patient. The RLA represents a combined diagnostic and therapeutic procedure for staging as well as removal of regional lymph node metastases in patients with malignant testis tumors. The disadvantage of the radical RLA is a 40 to 90% loss of potency. The risk of the reduced RLA is the relapse. The metastatic affection of the first retroperitoneal lymph node station, the so-called "sentinale" lymph nodes, allows a judgement for the remaining lymph nodes, and, therefore, for the extent of the necessary operation. The conventional frozen technique has a limited reliability, whereas the paraffin technique needs too much time. We used the immunohistochemistry as alternative method for the rapid as well as reliable evaluation of metastases. A group (7 cases) of 35 patients with non-seminomatous tumors of the testis was only treated by radical RLA after detection of CK-positive cells in the sentinale lymph nodes. The other patients were treated by modified RLA (20 cases) or reduced RLA (6 cases). The results were compared with a control group (48 cases) which was treated by radical RLA only. Using the modified RLA the relapse-free interval was not affected and the loss of ejaculation as a consequence of radical treatment could be avoided.(ABSTRACT TRUNCATED AT 250 WORDS)
