The man has four kidneys.

Hanoi – A 35-year-old patient went for a check-up for kidney stones due to severe lower back pain, and doctors discovered he had four kidneys in his body, a rare condition.

On March 22nd, Dr. Nguyen Dinh Lien, Head of the Department of Urology and Andrology at E Hospital, stated that the patient was admitted with severe lower back pain, abdominal distension, painful urination, and blood in the urine. Examination revealed a right ureteral stone.

Surprisingly, the CT scan revealed the patient had four kidneys, the doctor said. This abnormality is one of the causes of kidney stones. This is a rare congenital defect, where the kidneys develop abnormally during fetal development, and there are not many cases documented in world medical literature.

"Fortunately for the patient, all four kidneys and two separate ureters are correctly positioned within the bladder, thus eliminating many other dangerous complications," Mr. Lien said.

The patient underwent lithotripsy using laser therapy. This technique involves using an endoscope inserted through the urethra, bladder, and ureter to directly access the stone. Then, compressed air or laser energy is used to break the stone into fragments, which are then flushed and removed.

The patient has now recovered and is preparing for discharge.
