[Calicial diverticulum].

Area of Science:

• Urology
• Radiology
• Nephrology

Background:

• Caliceal diverticula are uncommon renal anomalies.
• Large caliceal diverticula present diagnostic and therapeutic challenges.

Observation:

• Five cases of large caliceal diverticula were analyzed.
• Symptoms often mimic complications due to non-specific presentation.
• Radiological diagnosis is crucial, emphasizing late-phase imaging.

Findings:

• Late contrast refilling and slow drainage indicate diverticular cavity.
• Communication with the renal pelvis or calix is a key diagnostic sign.
• The importance of late radiographic views for diagnosis is highlighted.

Implications:

• Asymptomatic cases warrant expectant management.
• Symptomatic or complicated cases require surgical intervention, including cystectomy and closure of the communication.
• Early and accurate diagnosis through advanced imaging is vital for appropriate patient management.
