摘要

Cystitis cystica is a hyper-proliferative condition affecting the urinary bladder mucosa, mainly involving the bladder neck and trigone. It has been found that upper urinary tract obstruction is associated along with and could be causative for cystitis cystica. In our case series, 50% patients presented with upper urinary tract obstruction caused by cystitis cystica involving both the ureteral orifices, which has been a revealing feature and not reported till date at this proportion. It is a single centre case series of 8 consecutive cases of cystitis cystica, with a follow-up of 22 months to 11 years. Four patients had onset of disease earlier, were managed elsewhere initially and then presented to our centre and four patients presented freshly to our centre. Diagnosis was confirmed in all patients by transurethral resection of bladder tumour. All the 8 patients in our study were males and their age ranged between 29 and 44 years. Out of the 8 patients, 6 had features of bilateral upper urinary tract obstruction. Among these, one patient had bilateral hydroureteronephrosis due to bladder neck elevation. Among the other 5 patients, 3 had initially presented with bilateral hydroureteronephrosis and one patient developed it over the course of the disease due to involvement of ureteral orifices by cystitis cystica; another patient developed right hydroureteronephrosis probably as a result of fibrosis of right vesicoureteral junction caused by previous transurethral resection of bladder tumour and left hydroureteronephrosis due to left distal ureteral growth and vesicoureteral junction calculus. 2 patients required bilateral laparoscopic extravesical ureteral reimplantation because of persistent symptomatic hydroureteronephrosis and deteriorating renal function. Our case series shows that upper urinary tract obstruction caused by cystitis cystica is not so uncommon. Persistent symptomatic hydroureteronephrosis may require bilateral ureteral reimplantation and laparoscopic extravesical technique is a viable option.
