Nephron-sparing surgery for renal cell carcinoma: detailed analysis of complications over a 15-year period.

PURPOSE: To assess the incidence of complications of conservative renal surgery for renal cell carcinoma in both elective and imperative indications, and its evolution over a 15 year period. PATIENTS AND METHODS: From 1988 to 2003, 127 patients underwent partial nephrectomy or tumorectomy for renal cell carcinoma in our department. INDICATIONs were imperative in 42% (n = 53) and elective in 58% (n=74) of cases. Morbidity was retrospectively assessed according to four parameters: 1- Period of surgery: A, from 1988 to 1999 and B, from 2000 to 2003. 2- INDICATION: elective vs. imperative. 3- experience of surgeon: senior vs. junior. 4- Nature of complications: minor or major. Comparative analysis was conducted using Chi-square and Fischer exact tests. RESULTS: Global incidence of complications was 30.7% (n = 39) corresponding to 18.1% minor (n = 23) and 12.6% (n = 16) major complications. Results show a moderate decrease of complication rate during Period B: 28.1% versus 32.9% during period A (p = 0.69). Complications occurred more frequently in imperative indications (49.1%) than in elective indications (17.6%) (p = 0.002), mostly regarding major complications (respectively 28.3% and 1.4%. (p < 0.001)). Overall re-intervention rate was 15.7%: 22.6% in imperative and 10.8% in elective indications (p = 0.008). Mean length of hospital stay was 14.1 days and significantly longer during period A (p = 0.003) and in imperative indications (p = 0.009). CONCLUSION: In our study, conservative renal surgery has a significant rate of complications which is extremely variable regarding to different parameters. Most discriminating factor was indication: in imperative indications, we observed a high rate of major complications (28.3%) that we consider acceptable to prevent anephria in clearly informed patients. Major complications are exceptional in elective indications. Decreased incidence of complications during the later period (B) is modest, and the role played by systematic pedicular clampage is discussed. As results published in medical literature are difficult to compare, we agree with authors who recently proposed to standardize complications data analysis, using a gravity scale, in order to provide relevant information to patients about statistical risks before surgery.

[Abdominoscrotal hydrocele]. / L'hydrocèle abdominoscrotale.

The abdominoscrotal hydrocele (ASH) is a rare variant of hydrocele of the tunica vaginalis with fluid accumulation into the abdominal cavity passing through the inguinal canal. The etiology of ASH is not clear. The positive diagnosis depends on the clinical data (hydrocele + abdominal mass). It is confirmed by means of echography and or by TDM. The treatment is surgical complete resection of the vaginalis with ligation of the peritoneal cavity. This report concerns the observation of a huge ASH, so far described in a literature review. We try to distinguish the diagnostic and therapeutic elements of this exceptional pathology.
