Studies in literature discussed the drawbacks of the ureteral access sheath use in flexible ureteroscopy and in the same time mentioned the benefits of ureteral access sheath in decreasing the incidence of urosepsis and better stone free rate. In the current study we aim to compare between percutaneous nephrostomy tube (PCN) insertion before flexible ureteroscopy and conventional ureteral access sheath (UAS) flexible ureteroscopy in terms of safety, efficacy and perioperative outcomes. In all, 100 Patients aged 20 to 67 years with upper ureteric stones and mild hydronephrosis or renal pelvic stones less than 20 mm with mild hydronephrosis were randomized into 2 groups; patients undergoing PCN insertion before flexible ureteroscopy, and patients undergoing the conventional UAS flexible ureteroscopy.

Here, we describe a case in which percutaneous nephrolithotomy was successfully used to fragment a large kidney allograft stone ≥20 mm in size.
Case Presentation: A 57-year-old woman who underwent ureteroureterostomy post simultaneous pancreas-kidney transplantation presented with gross hematuria after 15 years.

Purpose: Postoperative fever (POF)/urinary tract infection (UTI) is one of the most unpleasant and undesirable conditions for surgeons after retrograde intrarenal surgery (RIRS). RIRS is not recommended for any patient with a positive urine culture to avoid POF and UTI, but some patients may develop postoperative UTI even if the urine culture is sterile. This study investigated the predictive factors of fever and UTIs after RIRS.

The flexible and navigable suction ureteral access sheath (FANS-UAS) has increasingly been recognized as a potential game changer for retrograde intrarenal surgery (RIRS). While this innovative technology has demonstrated promising results in adult populations, there is a notable lack of evidence regarding its application in pediatric cases, particularly in comparison to conventional ureteral access sheaths (CUAS). This study aimed to perform a comparative analysis of pediatric kidney stone cases treated with RIRS using FANS-UAS and CUAS.
