Article Synopsis
- * Patients included a 67-year-old male and a 74-year-old male who received endoscopic ablation, and a 68-year-old female treated with percutaneous tumor resection.
- * Results indicated that kidney-sparing methods led to no recurrence of cancer in all patients, highlighting the importance of personalized treatment plans based on individual cases.
Background/objectives: Several surgical procedures have been proposed for the treatment of hypospadias, a common and heterogeneous congenital abnormality in males. Most surgeons utilize either a urethral stent or bladder catheter for 2-14 days as a postoperative urine diversion method depending on the severity of each case and the surgeon's preferences. The aim of the present study was to evaluate the feasibility of anterior and mid-penile hypospadias repair while placing the urethral catheter for only 20 h.

- The study aimed to assess the effectiveness and safety of using high-power Holmium: Yttrium-Aluminum-Garnet (Ho:YAG) lasers over 100 W for bladder stone treatment.
- An experimental setup involved testing on artificial stones and porcine bladder, while a clinical trial was conducted on 35 patients with various laser power settings.
- Results showed a 100% stone-free rate in patients, faster ablation rates with high power, and minimal complications, indicating that Ho:YAG laser lithotripsy is a safe and efficient method for treating bladder stones.
Objectives: To compare lithotripsy ablation rate with the Moses modes versus conventional pulse modes when using the Holmium:Yttrium-Aluminum-Garnet (Ho:YAG) laser.
Methods: The Lumenis® Pulse P120H Holmium Laser System and a 365 μm Moses D/F/L fiber were used to assess stone ablation rate in conventional Short and Long Pulse as well as Moses Contact and Distance at 10 W (0.5Jx20Hz and 2Jx5Hz) and 60 W (1Jx60Hz and 2Jx30Hz).
Robot-assisted surgery (RAS) has been integrated into clinical practice to overcome several limitations of conventional open or laparoscopic surgery. After the expiration of the long key patent period of Intuitive Surgical, various robotic systems (RSs) have been developed aiming at improving certain characteristics of the first robotic platform, the Da Vinci RS. This narrative review provides an overview of the current RSs used in urology along with the initial results from their application in urologic procedures.
