Urinary tract stone disease in Nairobi

At the Kenyatta National Hospital (KNH) and other private hospitals in Nairobi urinary stone disease is not being correctly diagnosed. Over a 15 year period (1980-1995) only 56 patients have been confirmed to have urinary tract stones out of the expected number of 220 patients. The age range was 10-60 Sears. The peak age was 30-40 years. Pain and haematuria were the commonest presenting symptoms. Ultrasonography and plane abdominal radiology were the commonest methods of diagnosis. Open surgery and endoscopic stone removal were the commonest modes of management. Extracorporeal shortwave lithotripsy (ESWL) has recently been introduced into the Nairobi Hospital, but was not functional at the lime of this study. Percutaneous nephrolithotomy (PCNL) is possible but has not been adequately used due to lack of correct equipment. Septicaemia and haemorrhage were the commonest complications of the open surgery.
