Flexible ureterorenoscopy combined with Holmium:YAG laser is an emerging technology that already has its place among the urologist's treatment options for the management of urinary stones. The main indication for the technique is renal stones, particularly lower caliceal stones. After mobilization of the stone in the renal pelvis or upper caliceal group, fragmentation is achieved by Holmium:YAG laser and the largest fragments are removed. When small fragments persist that are difficult to extract, the patient's blood is injected into the lower caliceal group to obtain a blood clot This clot then fills the lower caliceal group and prevents secondary accumulation of residual stone fragments, facilitating elimination of fragments towards the ureter. This article describes this technique.

Comparison of tip-bendable aspiration-assisted and standard access sheaths in the treatment of lower calyceal stones.

Objective: The aim of this study was to compare the success and complication rates of retrograde intrarenal surgery for lower calyceal renal stones performed with novel tip-bendable suction ureteral access sheaths and standard ureteral access sheaths.
Methods: Between March 2023 and March 2024, a total of 88 patients underwent retrograde intrarenal surgery for lower renal calyceal stones smaller than 20 mm. Based on the access sheath used, patients were divided into two groups: Group 1 (n=43) included patients treated with novel tip-bendable suction ureteral access sheaths and Group 2 (n=45) included patients treated with standard ureteral access sheaths.

Introduction: We describe a method of robotic ureterocalicostomy (RALUC) with the Da Vinci Single Port (SP) platform and present clinical outcomes in our cohort of patients.
Materials And Methods: We retrospectively reviewed all patients undergoing RALUC with the SP platform in a single-institution, IRB-approved database between 2020-2023. Demographics, preoperative, intraoperative, and postoperative outcomes were collated.

Objective: To compare upper, middle and lower calyceal accesses for prone percutaneous nephrolithotomy regarding stone-free rates, residual stones, haemoglobin drop and fluoroscopic time.
Methods: The prospective comparative clinical study was conducted from September 2018 to March 2021 at Al- Yarmouk Teaching Hospital, Baghdad, Iraq, and comprised patients of either gender aged 18-78 years with renal stones treated with percutaneous nephrolithotomy. They were divided into three groups on the basis of calyx access: upper calyx G1, mid-calyx G2, and lower calyx G3.
Clinical Significance of Tumor Location for Ureteroscopic Tumor Grading in Upper Tract Urothelial Carcinoma.

Although previous literature shows tumor location as a prognostic factor in upper tract urothelial carcinoma (UTUC), there remains uninvestigated regarding the impact of tumor location on grade concordance and discrepancies between ureteroscopic (URS) biopsy and final radical nephroureterectomy (RNU) pathology. In this international study, we retrospectively reviewed the records of 1,498 patients with UTUC who underwent diagnostic URS with concomitant biopsy followed by RNU between 2005 and 2020. Tumor location was divided into four sections: the calyceal-pelvic system, proximal ureter, middle ureter, and distal ureter.

Importance: Successful needle puncture of the renal collecting system is a critical but difficult procedure in percutaneous nephrolithotomy (PCNL). Although fluoroscopy and ultrasound are the standard imaging techniques to guide puncture during PCNL, both have known limitations.
Objective: To assess the feasibility and safety of a new navigation system for needle puncture in ultrasound-guided PCNL.
