🐾 Clinical Case Report | Urethral Obstruction Secondary to Urolithiasis | X-ray | Cystocentesis
A 1.5-year-old male patient was presented with a history of anuria, distended abdomen, lethargy and off feeding.
On abdominal palpation, a large, firm-to-hard, tense mass was palpable in the caudal abdominal region. Considering the history of anuria and the palpable mass, severe urinary bladder distension secondary to urinary outflow obstruction was suspected.
Abdominal radiography was subsequently performed, which confirmed marked urinary bladder distension with radiographic evidence consistent with urolithiasis/urinary tract calculi. The clinical and radiographic findings supported a diagnosis of urethral obstruction with severe urinary retention secondary to urolithiasis.
🚨 Due to the marked bladder distension and complete inability to urinate, cystocentesis was performed for urinary bladder decompression as an emergency stabilizing intervention.
🔬 Case Summary
Signalment: 1.5-year-old, Persian Male
Presenting signs: Anuria, lethargy, off feeding
Palpation: Large, firm/hard, distended urinary bladder suspected
Investigation: Abdominal X-ray
Radiographic finding: Markedly distended urinary bladder.
Diagnosis: Urolithiasis-associated urethral obstruction with severe urinary retention
Emergency intervention: Cystocentesis for bladder decompression
Biochemistry: Not performed in this case
⚠️ Urethral obstruction is a life-threatening emergency. Prolonged urinary obstruction can result in post-renal azotemia, electrolyte and acid–base disturbances, acute kidney injury, bladder damage/rupture and potentially fatal complications. Early recognition of the distended bladder and prompt decompression are therefore critical.
Proper palpation → Appropriate imaging → Accurate diagnosis → Timely intervention. 🩺🐾
