Comparison of frequency of heamaturia with rapid and slow decompression of urinary bladder in the management of chronic urinary retention

The objective of this study was to compare frequency of haematuria after slow decompression and rapid decompression of urinary bladder in the management of chronic urinary retention. Quasi experimental study. This study was carried out in Combined Military Hospital Quetta from May 2007 to Nov 2007. Sixty patients fulfilling the inclusion criteria were randomly assigned to two equal groups. Group A was subjected to intermittent clamping of Foley catheter and group B was subjected to no clamping of Foley catheter. On insertion of Foley catheter sample of urine was taken in a test tube and saved. A second sample was also taken in another test tube after one hour of complete decompression of either group and compared with original sample for occurrence of haematuria. Frequency of haematuria was calculated after both the procedures and recorded. confounding variables were traumatic catheterization and patients who were taking anticoagulants or having bleeding disorders. These were controlled by including only those cases where catheter was passed atraumatically by registrar surgery. The frequency of haematuria was found to be equal in both groups. Rapid decompression of the urinary bladder in cases of chronic urinary retention is a safe and convenient method of decompressing the urinary bladder in patients of chronic urinary retention, without any increase in frequency of haematuria
