To stent or not to stent perioperatively the ureteroileal anastomosis of ileal orthotopic bladder substitutes and ileal conduits? Results of a prospective randomized trial.

Purpose: We evaluated the impact of stenting the ureteroileal anastomosis on its competence, upper urinary tract dilatation, gastrointestinal recovery, metabolic parameters and patency rate after cystectomy with ileal bladder substitution or ileal conduit.

Materials And Methods: A total of 54 patients (37 with an ileal bladder substitute and 17 with an ileal conduit) were prospectively randomized into 2 groups, with (29) or without (25) perioperative stenting of the ureteroileal anastomosis. In all cases an end-to-side ureteroileal refluxing anastomosis was performed.

The template of the primary lymphatic landing sites of the prostate should be revisited: results of a multimodality mapping study.

Objectives: To map the primary prostatic lymphatic landing sites using a multimodality technique.

Methods: Thirty-four patients with organ-confined prostate cancer (cT1-cT2; cN0) underwent single-photon emission computed tomography fused with data from computed tomography (SPECT/CT) (n=33) or magnetic resonance imaging (SPECT/MRI) (n=1) 1h after ultrasound-guided intraprostatic injection of technecium (Tc-99m) nanocolloid. The presence of lymph nodes (LNs) containing Tc-99m was confirmed intraoperatively with a gamma probe.

Detection rate and operating time required for gamma probe-guided sentinel lymph node resection after injection of technetium-99m nanocolloid into the prostate with and without preoperative imaging.

Objective: To investigate the usefulness of presurgical image fusion of three-dimensional single photon emission computed tomography (SPECT) with computed tomography/magnetic resonance imaging (CT/MRI) for detecting primary prostatic lymphatic landing sites (sentinel lymph nodes [SLNs]) using an intraoperative gamma probe in patients undergoing radical prostatectomy for organ-confined prostate cancer after intraprostatic (99m)Tc-nanocolloid injection.

Methods: In 15 patients the surgeon was unaware of the preoperative SPECT/CT/MRI fusion imaging results. In 21 patients the surgeon was supported by the preoperative SPECT/CT/MRI images.
