To the Editor,

In this paper, we report a rare cause for post­kidney transplant proteinuria and hematuria. A 52-year-old man, a known case of end-stage renal disease (ESRD) due to polycystic kidney disease, who had undergone kidney transplant­tation presented to our clinic with dysuria and frequency associated with hematuria (8-10 RBC on urinalysis) and pyuria (WBC: 8-10 in urinalysis), two months after transplantation. On urine culture, Candida albicans was iso­lated and treatment with fluconazole was ini­tiated. At the next visit, the patient complained of abdominal pain. Physical examination re­vealed swelling and stiffness of the transplan­ted kidney. Urinalysis showed proteinuria, he­maturia (not dysmorphic RBCs), and pyuria (many WBC). The serum creatinine (Cr) was 2.79 mg/dL and the serum cyclosporine level was two times more than the previous level (601 ng/mL). The patient was hospitalized. A 24-hrs urine protein was 996 mg. Since the pa­tient was a transplant recipient, the possibility of retained double-J catheter in the urinary tract was considered. This was confirmed by ultrasound, which showed hydronephrosis in the transplanted kidney with a double-J cathe­ter that had been retained in the pelvis of the kidney. The catheter was removed and was associated with prompt improvement of signs and symptoms. At last follow-up, about one year after the removal of the double-J catheter, the patient remained asympomatic and the se­rum creatinine was 1.18 mg/dL and 24-hours urine protein was 55 mg. No hematuria was detected.

This case illustrates the clinical manifesta­tions of a retained double-J catheter following kidney transplantation. Thus, apart from known important causes of post-kidney transplant pro­teinuria such as recurrence of underlying di­sease, new renal disease, preservation-reper­fusion injury, and drug toxicity, [1] retained dou­ble-J catheter should be included in the dif­ferential diagnosis.
