Are warm ischemia and ischemia time still predictive factors of poor renal function after partial nephrectomy in the setting of elective indication?

Purpose: To evaluate renal function and to identify factors associated with renal dysfunction in the elective indications setting of nephron-sparing surgery (NSS).

Methods: We retrospectively reviewed operative data and glomerular filtration rate (GFR) of 519 patients treated by NSS in an elective indications setting between 1984 and 2006 in eight academic institutions. A GFR decrease under the thresholds of 60 or 45 ml/min at last follow-up was considered a significant renal dysfunction.

Comparison of oncological outcomes after segmental ureterectomy or radical nephroureterectomy in urothelial carcinomas of the upper urinary tract: results from a large French multicentre study.

Unlabelled: What's known on the subject? and What does the study add? Upper urinary tract urothelial carcinomas (UUT-UCs) are rare tumours. Because of the aggressive pattern of UC, radical nephroureterectomy (RNU) with bladder cuff removal remains the 'gold-standard' treatment. However, conservative strategies, such as segmental ureterectomy (SU) or endourological management, have also been developed in patients with imperative indications.

Assessment of oncologic control obtained after open versus laparoscopic nephroureterectomy for upper urinary tract urothelial carcinomas (UUT-UCs): results from a large French multicenter collaborative study.

Background: The purpose of this study was to compare the postsurgical survival of UUT-UC patients treated with ONU and LNU.

Methods: Using a multi-institutional, national, retrospective database, we identified patients with UUT-UC who underwent radical nephroureterectomy by open access (ONU) or by the minimally invasive alternative (LNU). Survival curves were estimated using Kaplan-Meier method.

Predictive factors for ipsilateral recurrence after nephron-sparing surgery in renal cell carcinoma.

Background: Ipsilateral recurrence after nephron-sparing surgery (NSS) is rare, and little is known about its specific determinants.

Objective: To determine clinical or pathologic features associated with ipsilateral recurrence after NSS performed for renal cell carcinoma (RCC).

Design, Setting, And Participants: We analysed 809 NSS procedures performed at eight academic institutions for sporadic RCCs retrospectively.

Partial versus radical nephrectomy in patients with adverse clinical or pathologic characteristics.

Objectives: To assess cancer-specific survival of partial nephrectomy (PN) patients with >or= 7-cm lesions or unfavorable pathology (stage T3a or Fuhrman grades III-IV).

Material And Methods: At 13 participation centers, 4072 partial or radical nephrectomies (RN) were performed for RCC between 1984 and 2001. Of all procedures, 925 (22.

Positive surgical margin appears to have negligible impact on survival of renal cell carcinomas treated by nephron-sparing surgery.

Background: The occurrence of positive surgical margins (PSMs) after partial nephrectomy (PN) is rare, and little is known about their natural history.

Objective: To identify predictive factors of cancer recurrence and related death in patients having a PSM following PN.

Design, Setting, And Participants: Some 111 patients with a PSM were identified from a multicentre retrospective survey and were compared with 664 negative surgical margin (NSM) patients.

[Preliminary results of botulinum toxin in the treatment of benign prostatic hyperplasia].

Botulinum toxin was first used in urology in the field of neuro-urology as treatment for detrusor-sphincter dyssynergia and incontinence due to neurogenic overactive bladder. Its action has now been clearly demonstrated and it is now widely used for the treatment of neurogenic overactive bladder. Can botulinum toxin also constitute an effective treatment for benign prostatic hyperplasia (BPH)? Intraprostatic botulinum toxin injections have been shown to have a significant clinical and urodynamic efficacy by acting on both the static and dynamic components of BPH.

Metachronous bilateral renal cell carcinoma: risk assessment, prognosis and relevance of the primary-free interval.

Purpose: We evaluated the prognosis, risk factors and relevance of the primary-free interval in a large cohort with metachronous bilateral renal cell carcinoma.

Materials And Methods: We studied 120 patients with metachronous, bilateral renal cell carcinoma who were treated at 12 international academic centers. Logistic regression was performed to evaluate risk factors for contralateral metachronous renal cell carcinoma during followup.

[Prospective evaluation of the effects of a practical introduction to urology session on the recruitment of urology intern in Paris: final results].

Objectives: To evaluate the effects of a practical introduction to urology session on the recruitment of Parisian interns since introduction of the National Classifying Examination.

Materials And Methods: Since 2004, all surgery interns appointed in Paris have participated in a practical introduction to urology session before starting work in hospital. They were asked to complete a questionnaire.

[Is the surgical training of French urologists more effective than that of urologists in other European countries?].

Objective: To compare the level of surgical training of French interns with that of interns in other European countries.

Material And Methods: Between 2005 and 2006, an exhaustive questionnaire (www.esnz.

[Comparison of open and laparoscopic partial nephrectomy: a French multicentre experience].

Objectives: To compare open (OPN) and laparoscopic (LPN) partial nephrectomy (PN) techniques in the light of a French multicentre series.

Material And Methods: Data corresponding to 741 PN (91 laparoscopic and 650 open procedures) were compared in terms of the indications, tumour diameter, operative data, complication rates and length of hospital stay.

Results: Tumours were smaller in the LPN group (2.

Morbidity and clinical outcome of nephron-sparing surgery in relation to tumour size and indication.

Objective: To analyse through a large multicentre series, morbidity of nephron-sparing surgery (NSS) in relation to tumour size and surgical indication.

Methods: The study included patients from eight international academic centres. Age, sex, TNM stage, tumour size, Fuhrman grade, Eastern Cooperative Oncology Group performance status (ECOG-PS), surgical margins, local and distant recurrences, and overall and cancer-specific survival rates were collected and analysed.

Pediatric urinary incontinence: evaluation of bladder wall wraparound sling procedure.

Purpose: In 1996 a surgical procedure for sphincter deficiency was reported in patients with neurogenic urinary incontinence. To our knowledge we report the first series that assesses this procedure since it was initially described.

Materials And Methods: Seven female and 7 male patients with spinal dysraphism and neurogenic intrinsic sphincter deficiency underwent surgery between 1997 and 2005.

[Lomboscopic surgery for renin-secreting tumour].

Renin-secreting tumour is a rare, benign entity, responsible for hypertension due to secondary hyperaldosteronism. It must be treated surgically. In the light of a review of the literature, the authors report the first published case of resection of a juxtaglomerular tumour of the kidney by laparoscopic partial nephrectomy using an ultrasound scalpel.

[Multilocular cystic nephroma in an adult: diagnostic and therapeutic strategy].

The authors report two clinical cases of cystic nephroma in adults observed in the department over the last 10 years. The nonspecific clinical findings and the poor contribution of imaging examinations make this rare disease difficult to diagnose. Only histological examination can confirm the diagnosis and eliminate multilocular cystic renal carcinoma or necrotic pseudocystic carcinoma.

[Can transobturator tape for urinary incontinence cause complete urinary retention?].

The surgical management of stress urinary incontinence has been revolutionized with the development of minimally invasive suburethral tape techniques, which ensure a high continence rate by means of a rapid procedure with a short hospital stay. Although morbidity and adverse effects are uncommon, they must be kept in mind in order to adopt an appropriate strategy designed to prevent their development. Urinary retention is the most frequent postoperative complication of retropubic tape.
