Prospective study of safety margins in partial nephrectomy: intraoperative assessment and contribution of frozen section analysis.

Objectives: To evaluate prospectively a healthy parenchymal safety margin during conservative surgery for renal cell carcinoma.

Methods: From 1997 to 2001, elective nephron-sparing surgery was performed through a flank incision in 61 consecutive patients (mean age 59.4 years, range 34.

[Laparoscopic kidney release for refractory chyluria].

Chyluria is a rare disease outside of parasite endemic zones. The treatment of severe forms is surgical. Reno-lymphatic disconnection is the reference procedure, with long-term success rates of 99%.

[Value of bootstrapping for small series of patients: application to survival analysis for 26 patients followed for bilateral sporadic renal cell carcinoma].

Objective: To use Bootstrapping to estimate the Kaplan-Meier survival of sporadic forms of bilateral renal cell carcinoma (RCC).

Patients And Methods: Over a period of 13 years, 759 patients were operated for RCC. 26 patients had bilateral sporadic RCC (3.

Prognostic factors for the survival of patients with papillary renal cell carcinoma: meaning of histological typing and multifocality.

Purpose: We identified prognostic factors of papillary renal cell carcinoma (PRCC) types 1 (PRCC1) and 2 (PRCC2).

Materials And Methods: Between 1985 and 1998, 759 patients underwent surgery for renal cell carcinoma, of whom 88 (11.6%), including 69 males and 19 females with a mean age of 61.
