Hydronephrosis Associated with Enlarged Lymph Nodes in the Patient with Tuberculous Mesenteric Lymphadenitis

Abstract

A common cause of hydronephrosis is an ureteral stone. Here, we report a rare case of enlarged lymph nodes-induced hydronephrosis.  The patient, who was suffering from fever, flank pain and hydronephrosis, had been treated with antibiotics and lithagogues for 3 months with the suspected diagnosis of calculous pyelonephritis, but had not shown any improvement. Finally, the patient was diagnosed as tuberculous mesenteric lymphadenitis and antituberculous therapy led to the improvement of the disease. So we could have a conclusion that the ureteral narrowing by compression of the tuberculously enlarged lymph nodes, not uretral stone, caused the hydronephrosis.
