Percutaneous nephrostomy for endopyelotomy [PDF]

American Journal of Roentgenology, 1987
Percutaneous full-thickness incision and stenting of the ureteropelvic junction (endopyelotomy) relieved obstruction in 33 (87%) of 38 patients treated over a 2-year period. Proper placement of the percutaneous nephrostomy tract through a posterior middle calyx and of a guidewire across the ureteropelvic junction is necessary in order to gain access to

Computed Tomography‐Guided Biopsy of a Ureteral Urothelial Carcinoma Mimicking a Submucosal Bladder Tumor at the Ureterovesical Junction

IJU Case Reports, Volume 9, Issue 1, January 2026.
ABSTRACT Introduction Intramural ureteral urothelial carcinoma can be difficult to diagnose, especially when presenting without mucosal abnormalities or positive cytology. In such cases, percutaneous biopsy may provide an alternative diagnostic approach.

NEPHROVESICAL SUBCUTANEUS STENT IN URETHERAL OBSTRUCTION DUE TO ABDOMINOPELVIC TUMOR: A CASE REPORT

Urology Research and Practice, 2019
Introduction: Abdominopelvic malignancies can cause ureteral obstruction. Since indwelling ureteral catheters are usually not sufficient enough to drainage the kidneys in these patients, percutaneous nephrostomy tubes are usually indicated.

The benefits of PCNL combined with ureterorenoscopy compared to isolated PCNL in urolithiasis (PRECISE): a multicentre randomised controlled trial protocol

BJU International, Volume 137, Issue 1, Page 76-86, January 2026.
Background Percutaneous nephrolithotomy (PCNL) often fails to achieve complete stone clearance with a single procedure. Residual fragments, irrespective of size, are associated with increased stone‐related morbidity and a higher likelihood of re‐intervention.

Vascular Involvement in Emphysematous Pyelonephritis

Case Reports in Urology, Volume 2026, Issue 1, 2026.
Emphysematous pyelonephritis is a life‐threatening, rapidly progressive necrotizing infection, characterized by the presence of gas in the affected tissues. Following a rare emphysematous pyelonephritis case which involved gas in the kidney and inferior vena cava vessels, we aimed to review the literature related to diagnosis and treatment.

Xanthogranulomatous Pyelonephritis Presenting as Significant Hydronephrosis in an Adult Male Who Was Managed with Robotic‐Assisted Radical Nephrectomy: A Case Report and Current Literature Review

Case Reports in Urology, Volume 2026, Issue 1, 2026.
Xanthogranulomatous pyelonephritis (XGP) is an infection of the kidney that often results from a chronic obstruction, such as a kidney stone. We present a patient with a massively enlarged left renal pelvis with minimal renal parenchyma presenting as an end stage ureteropelvic junction obstruction (UPJO). The patient was afebrile during his time in the
