We determined if serial screening ultrasounds are beneficial in evaluating for the development of Zinner syndrome in males with a congenital solitary kidney. All patients included had their congenital solitary kidney diagnosed at 20 years of age (P = .004). Serial ultrasounds reveal the onset of lower urinary tract and cyst-related pain symptoms are associated with the growth of the seminal vesicle cyst to ≥5 cm (P = .0198). Of symptomatic patients, 75% (8/12) had abnormal uroflows. Complete urodynamic studies revealed findings consistent with bladder outlet obstruction in 38% (3/8), equivocal for obstruction in 24% (2/8), and detrusor underactivity in 38% (3/8). Cyst excision effectively resolved voiding symptoms that were obstructive in etiology but failed to resolve symptoms in patients with detrusor underactivity. Serial ultrasound evaluations reveal that cyst growth to ≥5 cm in size is highly related to the onset of clinical symptoms, with the resolution of voiding symptoms by cyst excision directly associated with urodynamic findings.
