[Symptomatic urinary obstruction in patients with metastatic malignancies]

Area of Science:

• Urology
• Oncology

Background:

• Symptomatic urinary obstruction, marked by reduced or absent urinary outflow, frequently co-occurs with urological malignancies or abdominal metastases.
• While acute urinary obstruction presents as renal colic, chronic obstruction often remains undetected for extended periods.
• Causes include intrinsic upper urinary tract tumors and extrinsic ureteral compression by tumor masses.

Purpose of the Study:

• To outline the clinical presentation and management strategies for symptomatic urinary obstruction in cancer patients.

Main Methods:

• Review of clinical presentations of urinary obstruction in patients with urological malignancies.
• Discussion of diagnostic considerations and immediate management options.
• Consideration of long-term treatment based on prognosis.

Main Results:

• Urinary obstruction can be acute (renal colic) or chronic (often asymptomatic initially).
• External compression by tumors is a common cause of ureteral obstruction.
• Ureteral JJ stent placement or percutaneous nephrostomy provides prompt urinary disobstruction.

Conclusions:

• Prompt urinary disobstruction is crucial for managing symptomatic obstruction in cancer patients.
• Interventional procedures like ureteral stenting or nephrostomy offer immediate relief.
• Definitive surgical management should be tailored to the patient's overall prognosis and underlying malignancy.
