Introduction: Holmium laser enucleation of the prostate (HoLEP) is known to have a steep learning curve. The top-down technique was introduced to lessen the number of procedures required to master HoLEP. We aimed to present the experiences of two successive clinical fellows with the top-down HoLEP learning curve and compare their performance with the supervisor.

One of the challenging questions is when to perform pyeloplasty. We studied if improvement post-pyeloplasty in the first 3 months of life could show greater improvement in hydronephrosis than surgery at an older age.

Methods: We conducted a retrospective study of prospectively collected data from individuals who underwent GreenLight laser prostatectomy at our institution from May 2018 to July 2022. Patient demographics and outcome measures were recorded, including indications for the procedure, median urinary volume drained, or median postvoid residual urine volume (PVR) before catheterization or GreenLight laser prostatectomy.
Introduction: We sought to evaluate the reliability and validity of a new, illustrated questionnaire, the bladder bowel dysfunction symptom score (BBDSS) in the assessment of overactive bladder (OAB) and bladder bowel dysfunction (BBD).
Methods: The BBDSS questionnaire consisted of 12 structured questions. This pilot study was designed with two principal groups of questions: one group to assess bladder symptoms and the other to assess bowel dysfunction during the preceding month.
The study's primary objective was to compare the laser efficiency and clinical outcomes of two widely used systems, the holmium MOSES laser and the thulium fiber laser (TFL), in managing kidney stones. The secondary outcomes were to evaluate the impact of stone composition on laser efficacy. We conducted a retrospective review of patients who underwent flexible ureteroscopy (f-URS) for solitary renal calculi between December 2020 and August 2022 at our institution and had a 3-month postoperative CT scan.

In this study, we introduce a renogram scoring system that can help improve the prognostic value of MAG-3 renogram and in the decision making of pyeloplasty.
Patients And Methods: We retrospectively reviewed consecutive pyeloplasties for antenatal hydronephrosis from 2010 to 2020.
Introduction: The anteroposterior diameter (APD) of the renal pelvis is a commonly used ultrasound parameter in the evaluation and management of hydronephrosis. It has been established that an APD value associated with pyeloplasty is around 25 mm. Some believe the APD should be measured at the innermost part of the renal pelvis while others suggest that it should be done at the renal contour.

The objective of this study was to assess the safety and efficacy of MOSESTM technology versus the thulium fiber laser (TFL) in patients with BPH undergoing transurethral enucleation of the prostate.
Methods: We conducted a retrospective review of prospectively collected data of eighty-two patients who underwent transurethral enucleation of the prostate using MOSESTM or TFL technologies from August 2020 to September 2021.
Objective: To determine the safety and efficacy of same-day urethral catheter removal after laser vaporization of the prostate and to identify factors contributing to a successful trial of void (TOV).
Methods: We conducted a retrospective analysis of 98 patients who underwent laser vaporization of the prostate using GreenLight or Holmium Xpeeda laser fibers from April 2018 to March 2021. All patients included in the study were offered a same-day TOV and had their catheters removed 3 hours postoperatively.
Introduction And Objective: The value of diuretic renography drainage times in congenital hydronephrosis (AHN) decision making is controversial. Recently, a group suggested a modification to the classically described diuretic drainage time cut-off values. They found that a drainage half-time (T) < 5 min was normal whereas a T exceeding 75 min predicted pyeloplasty.

Patients And Methods: We retrospectively reviewed the charts of prospectively collected patients who underwent Top-Down HoLEP between 2017 and 2018. All cases were operated upon by a single urologist (H.
Objective: To evaluate the efficacy of ambulatory mini percutaneous nephrolithotomy (Mini-PCNL) and flexible ureteroscope (F-URS) in treating 10-20 mm lower calyceal stones using propensity score matching analysis (PSM).
Patients And Methods: A retrospective analysis of 136 adult patients that underwent Mini-PCNL or F-URS for a single lower calyx calculus. Participants that underwent F-URS were allocated to Group I, while those who underwent Mini-PCNL were assigned to Group II.
Objectives: To evaluate the safety and efficacy of combined top and down low power thulium laser enucleation of the prostate (ThuLEP).
Patients And Methods: Between May 2017 and May 2019, after institutional board review approval, successfully consented patients underwent combined top and down low power ThuLEP. We used a 30 -W Thulium laser with a 550 μm laser fiber and a 26 Fr continuous flow resectoscope.
