Purpose: The thulium laser is the most recently introduced technology for the surgical treatment of benign prostatic hyperplasia (BPH). Until recently, most thulium laser enucleation of the prostate (ThuLEP) was performed by use of the three-lobe technique. We introduce a novel one-lobe enucleation technique for ThuLEP called the "All-in-One" technique.

Objective: To investigate whether a triple combination of early-differentiated cells derived from human amniotic fluid stem cells (hAFSCs) would show synergistic effects in urethral sphincter regeneration.

Materials And Methods: We early-differentiated hAFSCs into muscle, neuron and endothelial progenitor cells and then injected them into the urethral sphincter region of pudendal neurectomized ICR mice, as single-cell, double-cell or triple-cell combinations. Urodynamic studies and histological, immunohistochemical and molecular analyses were performed.

Purpose: In recent years, laser surgery has been widely used to treat benign prostatic hyperplasia (BPH). A thulium:yttrium-aluminium-garnet (Tm:YAG) laser was recently introduced for BPH surgery. We compared the effectiveness and safety of Tm:YAG laser vaporesection of the prostate (ThuVaRP) with that of bipolar transurethral resection of the prostate (TURP).

Purpose: Several recent studies have reported the benefits of tubeless percutaneous nephrolithotomy (PNL). Postoperatively, tubeless PNL patients have an indwelling ureteral stent placed, which is often associated with stent-related morbidity. We have performed totally tubeless (tubeless and stentless) PNL in which no nephrostomy tube or ureteral stent is placed postoperatively.

Purpose: We introduce our transient vascular occlusion technique that uses a vessel loop and Hem-o-Lok clips in laparoscopic partial nephrectomy.

Materials And Methods: From March 2009 to March 2011, 15 consecutive patients underwent laparoscopic partial nephrectomy. All operations were performed by a single surgeon using the transperitoneal approach.

Purpose: Laparoscopic simple prostatectomy was recently developed to treat voluminous benign prostatic hyperplasia (BPH). We describe the surgical technique and assess the feasibility of laparoscopic simple prostatectomy through our early experience.

Materials And Methods: The medical records of 11 patients who underwent laparoscopic simple prostatectomy between March 2008 and January 2010 were retrospectively analyzed.
