Purpose: Salvage prostate permanent implant (sPPI) for postradiation local failure provides high rates of biochemical control. The cumulative dose delivered to the prostate and the rectum is still unknown.

Methods And Materials: We reviewed the postimplant CT-based dosimetry of 18 selected patients who underwent sPPI with (125)I seeds for isolated biopsy-proven local failure several years after external beam radiation therapy.

Purpose: To determine whether post-implant MRI-based dosimetry of the Dominant Intra-prostatic Lesion (DIL) could best predict the occurrence of PSA bounce after prostate brachytherapy.

Methods And Materials: We selected 66 patients with a low risk prostate cancer treated with (125)I prostate brachytherapy as monotherapy. Post-implant dosimetry based on day 30 CT-scan and multiparametric MRI co-registration was generated: planned D90, D95, V100, V150 values were calculated for each DIL.

Nephron sparing surgery (NSS) results in the transplanted population remain unknown because they are only presented in small series or case reports. Our objective was to study renal sparing surgery for kidney graft renal cell carcinomas (RCC) in a multicenter cohort. Data were collected from 32 French transplantation centers.

De novo tumors in renal allografts are rare and their prevalence is underestimated. We therefore analyzed renal cell carcinomas arising in renal allografts through a retrospective French renal transplant cohort. We performed a retrospective, multicentric survey by sending questionnaires to all French kidney transplantation centers.

Objective: To study the natural history of renal cell carcinoma (RCC) development in renal grafts and their management.

Patients And Methods: We report a single-centre series of de novo RCC in allografts from a cohort of 2396 consecutive renal transplant recipients.

Results: In all, 17 RCCs were detected in 12 patients, representing 0.

Purpose: Renal cell carcinoma in a renal graft is a rare condition whose incidence will increase in the future. To our knowledge no standardized treatment has been established for this disease. We performed a prospective study of nephron sparing surgery for small renal cell carcinoma in renal grafts.

Introduction: Endoscopic placement of ureteric stents was first described in 1967 by Zimskind. Few studies have evaluated the impact of double J ureteric stents on the patient's quality of life. This prospective study was designed to evaluate the safety and morbidity associated with ureteric stents.

Introduction And Objectives: Miniaturization and development of flexible instruments have led to the development of flexible ureterorenoscopy. The objective of this study was to compare the capacities of active deflection of two latest generation flexible ureterorenoscopes and to evaluate alteration of deflection and flow of irrigating fluid in the presence of instruments in the operating channel.

Material And Methods: Two ureterorenoscopes were evaluated in this study.

Flexible ureterorenoscopy combined with Holmium:YAG laser is an emerging technology that already has its place among the urologist's treatment options for the management of urinary stones. The main indication for the technique is renal stones, particularly lower caliceal stones. After mobilization of the stone in the renal pelvis or upper caliceal group, fragmentation is achieved by Holmium:YAG laser and the largest fragments are removed.

A caliceal diverticulum corresponds to a cavity communicating with the renal excretory tract via a neck. Surgical treatment is required when the caliceal diverticulum is symptomatic with repercussions on the patient's quality of life. A retrograde approach via holmium:YAG laser ureterorenoscopy has been recently used to treat the stone and externalize the caliceal diverticulum into the pyelocaliceal cavities.
