Clinical research on the possibility that renal cysts may be responsible for the appearance of hematuria

: New techniques of study, namely echography, urography, TC, give evidence of a great number of asymptomatic renal cysts in the everyday experience. Then also if haematuria was classically considered one of the symptoms of renal cysts, there are now many reasons to consider such evidence very infrequent, and downright there are some valid doubts that renal cysts may cause haematuria at all. So the authors have analysed 113 patients, most of them coming from Institute of Radiology of Chieti University Faculty of Medicine; all of them had renal cysts diagnosed by echographs and/or urography but only a minority were just from the beginning studied for haematuria, whereas the majority for many different symptoms. Total cases was then divided into two groups: one of 102 patients, all without haematuria; 78 of them had been studied only with echography, whereas other 24 patients had been examined both with echography and urography. The second group, of 11 cases, included all the patients who had both renal cysts and haematuria. Only in two cases of this second group was lacking evidence of any associated pathology which must be responsible for haematuria, whereas in all the other 9 cases a different aetiology of the haematuria was demonstrated, for simultaneous presence of various pathologies (cystopyelitis with associated prostatis, haemorrhagic cystitis, bladder diverticula and renal papillomas and upper urinary ways tumours), all much easier responsible by themselves of haematuria, also if with different features from case to case.(ABSTRACT TRUNCATED AT 250 WORDS)
