[Causes and course of fornix rupture].

PURPOSE

Fornix rupture is a urological emergency situation. In most cases ureteral stones represent the underlying cause. We present the largest series ever reported.

MATERIAL AND METHODS

Between 1994 bis 2005 a total of 162 patients were diagnosed with a fornix rupture. There were 121 men and 41 women with a median age of 53 years (range: 20-79 years). We investigated the following parameters: underlying cause of fornix rupture, symptoms, diagnostic and therapeutic procedures.

RESULTS

In 60% of cases a ureteral stone was found as cause and in another 28% we found no reason for fornix rupture. 93% of patients had one or more symptoms at the time of diagnosis. In all patients primary endoscopic therapy (96%) or insertion of a nephrostomy tube was performed (4%). Also, antibiotic treatment was given in 92% of patients. No patient developed a perirenal abscess or other relevant complication requiring open operative revision.

CONCLUSIONS

We confirm that ureteral stones are the most frequent causes of fornix rupture. With a low pressure system and antibiotic treatment, secondary complications can be effectively prevented.
