Urinary Tract Calculi VI: Surgical Management

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Summary

This summary is machine-generated.

A rare upper urinary tract (UUT) lipoma was diagnosed in a 41-year-old man. Initial treatment involved standard surgery, but examination revealed a benign lipomatous tumor, suggesting a minimally invasive approach may be suitable.

Urology
Oncology
Pathology

Background:

Benign tumors of the upper urinary tract (UUT) are infrequent.
Lipomas are rare neoplasms, with UUT lipomas being exceptionally uncommon.

Purpose of the Study:

To report a rare case of upper urinary tract lipoma.
To discuss the diagnostic and management considerations for UUT lipomas.

Main Methods:

Case presentation of a 41-year-old male with left flank pain.
Diagnostic workup included computed tomographic urography.
Surgical management involved nephroureterectomy with bladder cuff excision.

Main Results:

Computed tomographic urography showed irregular thickening of the left renal collecting system.
Histopathological examination confirmed a benign lipomatous tumor, not malignancy.
The patient underwent a standard surgical procedure for a presumed UUT tumor.

Conclusions:

This case represents the first reported instance of a UUT lipoma managed initially with a standard surgical approach.
The findings suggest that a minimally invasive approach might be considered for UUT lipomas, pending further evidence.
Accurate preoperative diagnosis is crucial for appropriate management of UUT benign tumors.
