The accuracy of renal tumor biopsy: analysis from a national prospective study.

Objective: To assess preoperative renal tumor biopsy (RTB) accuracy.

Materials And Methods: As part of the prospective NEPHRON study, data from 1,237 renal tumors were collected, including the use and results of RTB and final histology following nephrectomy. During the 6 months period of inclusion, 130 preoperative biopsies were performed.

Is there a volume-outcome relationship for partial nephrectomy?

Objective: To investigate the impact of hospital volume on partial nephrectomy indications and outcomes.

Materials And Methods: Data were extracted from the National Observational Registry on the Practice and Hemostasis in Partial Nephrectomy registry. Four groups were created according to the number of partial nephrectomy (PN) performed: very high (VH, ≥ 19 PN), high (H, 10-18 PN), moderate (M, 4-9 PN) and low (L, <4 PN) PN activity.

National prospective study on the use of local haemostatic agents during partial nephrectomy.

Objective: To assess the use of local haemostatic agents (HAs) in a prospective multicentre large series of partial nephrectomies (PNs).

Patients And Methods: Prospective National Observational Registry on the Practices of Haemostasis in Partial Nephrectomy (NEPHRON): the study was conducted in 54 French urological centres from 1 June to 31 December 2010. In all, 570 consecutive patients undergoing a PN were enrolled in this study in a prospective manner.

[Stress urinary incontinence in women. Physiopathology and surgical treatment using Burch's technique and TVT].

FROM PHYSIOPATHOLOGY TO TREATMENT: Urinary incontinence on effort in women is due to a default in sub-urethral anatomical structure, which leads to incontinence on effort (coughing, laughing, carrying heavy weights, physical activity). When re-education fails, surgical treatment using Burch's technique or the placing of sub-urethral TVT (Tension free Vaginal Tape) is generally proposed. BURCH'S TECHNIQUE: Burch's technique consists in an upper tract colposuspension via coelioscopy or laparotomy, under rachis or general anaesthesia.

[Economic comparison of 2 surgical techniques fr the treatment of stress urinary incontinence in women: Burch's technique versus the TVT technique].

The TVT device (Tension-free Vaginal Tape) is used in our Hospital to treat stress urinary incontinence, resulting in an excess cost for the Pharmacy. The Burch technique, used previously, does not require any specific medical device, but is invasive and requires a longer hospital stay. The objective of this study was to compare the financial impact of these two techniques, by defining the discriminant costs.
