An Extremely Rare Case of Lower Urinary Tract Symptoms: Floating Benign Mesenchymal Mass in Abdomen

الملخص EN

A 48-year-old man admitted to the urology outpatient clinic with major symptoms of right-side pain and intermittent lower urinary tract symptoms (LUTSs) such as low urine flow rate, dysuria, and frequency.

Uroflowmetry showed low urine flow, and laboratory tests revealed no pathology.

Ultrasound (US) showed a 7 cm calcific mass above the bladder and a kidney cyst with a diameter of 5.3 cm in the upper pole of the right kidney.

Enhanced computed tomography confirmed the US findings.

Laparoscopic transperitoneal renal cyst decortication was performed.

There was no sign of additional tumors.

An independent mass in the abdomen was diagnosed, and the mass was removed.

Based on the pathology, the diagnosis was a benign mesenchymal calcific mass.

This is the first report of LUTSs due to a free benign mesenchymal mass in the published literature.
