Cystitis with ureteral reflux caused by ureaplasma urealyticum.
The authors present a case of a fifteen-year-old boy with urgency, suprapubic pain, hematuria, and pyuria with negative routine urine cultures. Cystoscopy revealed gross cystitis, and VCUG showed bilateral reflux and ureteral dilatation. Renal arteriograms, percutaneous renal biopsy, and bladder biopsy also were performed. After finding a positive culture for Ureaplasma, therapy with doxycycline rendered the patient asymptomatic and reflux improved on follow-up VCUG. Ureaplasma urealyticum should be considered in patients with symptomatic pyuria and negative routine cultures. Ureteral reflux, reversible with appropriate therapy, may be part of the infectious process.
