INTRODUCTION: Robotic technology has been increasingly utilized for complicated reconstructive surgeries in pediatric urology, such as ureteroureterostomy (UU). The literature is limited regarding the performance of minimally invasive UU in children, and the existing published series utilize indwelling ureteral stents. We sought to report on our pediatric experience with robot-assisted laparoscopic (RAL)-UU using a temporary ureteral catheter in duplex systems with ureteral ectopia. METHODS: A retrospective chart review was performed of all pediatric patients who underwent RAL-UU at a single institution over a 2-year period...

A continuous-wave (CW) as well as quasi-continuous wave (QCW) thulium-doped all-fiber laser at 1.94 μm has been designed for targeting applications in urology. The thulium-doped active fiber with an octagonal-shaped inner cladding is pumped at 793 nm to achieve stable CW laser power of 10 W with 32% lasing efficiency (against launched pump power). The linear variation of laser power with pump offers a scope of further power scaling. A QCW operation with variation of duty cycle from 0.5% to 90%, repetition rate from 0...

OBJECTIVE: To investigate tyrosine kinase inhibitors (TKI) and gold nanorod (AuNR) paired with photothermal ablation in a human metastatic clear cell renal cell carcinoma mouse model. Nanoparticles have been successful as platform for targeted drug delivery in the treatment of urologic cancers. Likewise, the use of nanoparticles in photothermal tumor ablation, though early in its development, has provided promising results. Our previous in vitro studies of nanoparticles loaded with both TKI and gold nanorods and activated with photothermal ablation have demonstrated significant synergistic cell kill greater than each individual arm alone...

Introduction. Retrocaval ureter is a rare congenital anomaly. Open surgery was the classic treatment for this condition. Laparoscopy is currently an admitted procedure to treat many urological diseases. The objective of our study is to present our experience and discuss the safety and the feasibility of transperitoneal laparoscopic pyelopyelostomy for treatment of retrocaval ureter (RCU). Materials and Methods. Three symptomatic patients underwent laparoscopic repair for RCU in our department. The diagnosis was suspected on the computed tomography scan (CT) and confirmed on ascending pyelography...

INTRODUCTION: Conventionally, individual ligation of the renal vessels with clips is performed during laparoscopic nephrectomy (LN). Concomitant ligation of the vessels is not a standard procedure due to an expected risk of stapler dysfunction and the development of arteriovenous fistulas (AVF). Using the EndoGIA stapler 45/2.5 mm, we compared en bloc ligation with individual ligation during LN and nephroureterectomy (LNU) with a special focus on the development of AVF and technique safety...
