PURPOSE To our knowledge despite numerous studies the biological effect of extracorporeal shock wave lithotripsy (ESWL, Dornier Medical Systems, Inc., Marietta, Georgia) on the function of the immature kidney has not yet been evaluated. We determined the short-term effect of ESWL on renal function in children. MATERIALS AND METHODS In a 5-year period 65 children were treated for 77 kidney stones by ESWL and followed regularly at our department. In 16 children the short-term effect of shock wave energy was studied by measuring blood parameters (sodium, potassium, urea, creatinine and C-reactive protein), urinary electrolytes (sodium, potassium and creatinine), urinary enzyme activity (aspartate transaminase, alanine transferase, alkaline phosphatase and lactate dehydrogenase) and the excretion of beta 2-microglobulin. Samples were obtained immediately before and 2 hours after ESWL, and on days 1, 2, 8, 15, 30 and 90 after treatment. RESULTS Morphological changes in the kidneys were not detected by ultrasound during followup. No significant changes were noted in overall renal function, serum parameters or urine electrolytes. A significant elevation in the excretion of aspartate transaminase, alkaline phosphatase, lactate dehydrogenase and beta 2-microglobulin was observed, indicating proximal tubular dysfunction and cell destruction. Enzyme levels returned to baseline within 15 days. CONCLUSIONS Our results demonstrate that shock wave energy induces transient functional damage of tubular function in children. Minimizing the kV. and number of shocks may decrease the deleterious effect. When considering functional regeneration time, the minimal interval between 2 shock wave treatments should be at least 15 days. The long-term effect needs further investigation.

690 patients were treated for testicular tumour in the course of 18 years. The histology of 7 cases showed Leydig cell tumour. In 4 of the 7 cases, a metastatic process leading to death was observed. At the time of diagnosis, 5 patients were found to have low stage, whereas 2 of the patients had advanced lymphatic involvement. The hematogenous and lymphatic metastases proved to be resistant to chemotherapy. Contrary to the major part of the literature, retroperitoneal lymphadenectomy should be performed with this histological type for the exact pathological staging immediately following orchiectomy.

OBJECTIVES To describe our experience and 1-year follow-up of 3 patients with circumcaval ureter (CU) treated laparoscopically, with the introduction of a new stenting method and review of the published data. Because of its rarity, more reports are needed to advocate more comprehensive knowledge about the preferred surgical technique for the treatment of CU. METHODS Since November 2005, 3 patients with symptomatic CU have undergone laparoscopic repair of their anomaly at our institutes. In all 3 cases, the ureter was transected and positioned anteriorly with an end-to-end anastomosis. In 2 cases, the retrocavally located ureteral segment was resected. RESULTS The mean operative time in our series was 210 minutes, without any intraoperative or early postoperative complications. In 1 patient, a slight ureteral stricture was detected that resolved with reinsertion of a double-J stent. Histopathologic examination of the resected ureteral segments revealed sclerosis and muscular hypertrophy. All patients remained symptom free during the 1 year of follow-up. CONCLUSIONS With all the advantages of a minimally invasive procedure and preserving therapeutic efficacy, the laparoscopic approach should be considered a standard choice for surgical treatment of CU in symptomatic patients. Care should be taken to diagnose and excise the pathologically narrowed ureteral segment.

The aims of this study were to investigate the potential of β‐catenin as a biomarker for predicting cancer‐specific survival, and to find a reproducible mode of evaluation of immunohistochemistry.
