Diagnosis and treatment of renal tuberculosis(report of 52 cases) / 中华泌尿外科杂志

ABSTRACT

Objective To investigate the clinical manifestations,diagnosis and treatment of renal tuberculosis(TB). Methods This series included 52 patients with renal TB.Of them 36 cases (69%) presented with irritative symptoms.10 cases (19%) had lumbago accompanied by hematuria.6 cases (11%) had renal angina and 6(11%) painless hematuria.B-ultrasonography suggested renal TB in 20 cases and unilateral hydronephrosis in 22 cases;renogram showed that the diseased kidneys had no function in 31 cases.Urinal AFB and tuberculosis PCR(Tb-PCR) were performed in 38 cases,the results were positive in 13(34%)and 21(55%),respectively.27 cases were misdiagnosed to have calculi or inflammation.Treatments consisted of antituberculous chemotherapy in 12 cases (23%)and surgery in 40(77%). Results All of the 12 cases who received medications recovered completely.40 cases undergoing surgery were pathologically diagnosed to have renal TB;of them 5 cases developed ureteral stump syndrome. Conclusions Urine AFB and Tb-PCR remain the primary diagnostic methods before operation.When the non-functioning kidney is resected,the involved ureter should be concomitantly resected as much as possible.
