Feasibility, efficacy, and safety of retrograde intrarenal surgery in <1-year age group: A single-center experience.

Purpose: Urolithiasis in infants is uncommon. Percutaneous nephrolithotomy, extracorporeal shockwave lithotripsy, and retrograde intrarenal surgery (RIRS) are the management options. RIRS is the least studied of these options in infants.

Ureteroscopic lithotripsy by thulium fiber laser versus holmium laser: A single-center prospective randomized study.

Objective: Laser lithotripsy has been the standard of care for lower and mid-ureteric calculi. Thulium fiber laser (TFL) is a new introduction to this field, which has been extensively studied for retrograde intrarenal surgery. We have done a prospective randomized study of ureteroscopic lithotripsy between TFL and holmium: Yttrium-aluminum-garnet (HO: YAG) laser to know the efficacy of stone fragmentation, stone-free rate, and complications.

A multicentric non-randomized prospective observational study on the clinical efficiency of thulium fibre laser in large volume stones (> 1000 mm).

Purpose: Our objective was to analyse the clinical efficiency of TFL in large volume stones during retrograde intrarenal surgery.

Materials And Methods: Patients with large volume renal stones (> 1000 mm) operated at two different centres, from May 2020 to April 2021, were enrolled in this study. Retrograde intrarenal surgery was performed using 60W Superpulse thulium fibre laser™ (IPG Photonics, Russia).

Durability of current generation flexible ureteroscopes: the experience from a high-volume centre.

Introduction: The aim of this article was to evaluate the durability of current generation fibreoptic flexible ureteroscopes (FURS), analyse factors that influence durability, identify reasons for premature damage of FURS and offer suggestions to expand its life span.

Material And Methods: A total of 952 retrograde intrarenal surgeries (RIRS) done for upper tract calculi using 8 fibreoptic FURS, namely three Storz Flex X2, one Flex X2S, two Olympus URF- P6, two Olympus URF- P7, between March 2013 and December 2018, were reviewed retrospectively. All procedures were done by two consultants, in a single referral centre.

Occult penile fracture: An atypical presentation.

Penile fracture is a urological emergency. Most cases are under reported due to social stigma. It is caused by rupture of the tunica -albuginea of corpora cavernosa.

Emphysematous pyelonephritis with gas in inferior vena cava.

Emphysematous pyelonephritis (EPN) is a progressive necrotizing infection of the renal parenchyma, collecting system and perinephric tissue. A 36-year female with uncontrolled diabetes, presented with left emphysematous pyelonephritis, with air in the infra-hepatic inferior vena cava (IVC). She was hydrated, treated with intravenous antibiotics, insulin.

Supine percutaneous nephrolithotomy in a 9-month infant.

Treatment of nephrolithiasis in infants is challenging. There are no separate guidelines for the management of renal stones in infants. There is a recent surge in doing PCNL in supine position.

Bilateral simultaneous RIRS for calculus anuria in a 4 months male baby.

Treatment of pediatric stone disease is a challenge, more so, in the case of infants. Infantile anuria due to calculus disease is rare, as pre-renal causes predominate. Retrograde intrarenal surgery is a less often sorted modality in infants, due to the lingering skepticism regarding handling pediatric ureters and urethra.
