AI Article Synopsis
- The study investigates the relationship between perirenal fat stranding (PFS) and post-operative infectious complications in patients undergoing ureterorenoscopy (URS) for ureteral stones.
- A total of 602 patients were analyzed, with 72 showing PFS; results indicated that those with PFS had increased rates of fever, urinary tract infections, and urosepsis compared to those without PFS.
- The findings suggest that the presence of PFS in ureteral stone patients significantly raises the risk of post-operative complications like infections and ureteral injuries.
Article Abstract
Objective: Perirenal fat stranding (PFS) is linear areas of soft-tissue attenuation in the perirenal space on non-contrast computed tomography. The present study aimed to investigate whether PFS is associated with infectious complications after ureterorenoscopy (URS) in patients with ureteral calculi in any location.
Methods: The data of 602 patients with ureteral stones who underwent URS were analyzed retrospectively. The patients were divided into two groups as Group 1 (PFS not detected) and Group 2 (PFS detected). Gender, and age of patients, size, side, and location of the stone, operation time, double-J stent insertion status, perioperative ureter injury, postoperative infection after URS and related complications, and duration of hospital stay were compared.
Results: While PFS was not detected in 530 patients, PFS was detected in 72 patients. The mean age, male/female ratio, side and localization of the stones, operation time, and perioperative insertion of the double-J after lithotripsy were statistically similar (>0.05). The median stone diameter was smaller in Group 2 (9 mm 8 mm) (=0.033). Fever was observed in 30 and 38 patients in Group 1 and Group 2, respectively (=0.0001). Urinary tract infection was detected in 24 and 27 patients in Group 1 and Group 2, respectively (=0.0001). The urosepsis did not occur in any patients in Group 1, whereas 8 (11.1%) patients in Group 2 experienced urosepsis (=0.0001).
Conclusion: According to the results of the present study, patients with ureteral stones accompanied by PFS are much more prone to ureteral injuries and infectious complications such as urinary tract infection, fever, and sepsis after URS.

Department of Urology, First Affiliated Hospital of Gannan Medical University, Ganzhou, Jiangxi, China.
Objectives: To present our initial experience of robotic ureteroplasty with lower-lip mucosal graft (LLMG) for treating ureteral stenosis longer than 2 cm and evaluate its feasibility and efficacy.
Materials And Methods: A total of thirteen patients with ureteral stenosis who underwent robotic ureteroplasty with LLMG were retrospectively analyzed. After identification and dissection of the ureteral stenosis segment, the segment was incised longitudinally.

Department of Urology, Oxford University Hospitals NHS Trust, Oxford, Oxfordshire, UK.
Purpose: To compare stone clearance and complications between a 'wide' (9 × 50 mm) and 'narrow' shockwave focus (6 × 28 mm) when undertaking shockwave lithotripsy (SWL) in patients with renal or ureteric stones.
Methods: Data from patients undergoing SWL using the dual focus Storz Modulith SLX-F2 lithotripter at a single centre were prospectively collected between February 2018 and September 2020. Patients were matched by stone size, location, and number of treatments.

Endometriosis is a common condition among women of reproductive age worldwide, with the urinary tract being the second most frequently affected extragenital organ system, particularly the bladder and ureters. Ureteral endometriosis (UE) is relatively rare, often asymptomatic, and can lead to progressive renal function loss if not addressed promptly. Early diagnosis and intervention are essential, requiring a high index of suspicion.

Background: This study aimed to investigate initial experiences and outcomes of a retrograde inserted new silicone-covered metallic ureteric stent (Urexel™) for malignant ureteric obstruction.
Methods: We retrospectively reviewed the medical records for 12 consecutive patients who underwent Urexel™ stent placement for malignant ureteric obstruction from March 2020 to March 2021. The Urexel™ stent is a segmental metallic ureteric stent composed of a nitinol mesh covered with a silicone membrane.
