title: Ascending uretero-pyelography in renal failure.
abstract: Ascending uretero-pyelography has been carried out over a period of 13 years in 97 consecutive patients with undiagnosed renal failure. Sixty-nine were in a non-obstructive uropathy group while 26 had ureteric obstructions. There were two failures. Over 60% of examinations were performed under local anaesthesia, each examination taking an average of 20 min. There has been no mortality and two anaesthetic complications have been the only significant morbidity. Ureteric injury, urinary infection and renal function have all been investigated and recorded. Five per cent of patients developed urinary infection following AUP but without any major consequences. No significant ureteric injury occurred and no late sequelae were noted. Neither any reaction to contrast medium nor any further deterioration in renal function was observed; AUP was diagnostic in 46% of patients. In the remainder it ruled out obstructive uropathy and gave useful information about the kidneys, ureters and bladder. In experienced hands and with proper facilities AUP is safe and can be helpful in the diagnosis and management of patients in renal failure.
