BACKGROUND: Diuretic therapy after transurethral prostatectomy (TURP) is primarily intended to induce diuresis against water intoxication and cystic clot retention. This study was undertaken to compare the diuretic effects of glycerol with furosemide after TURP.
METHODS: Thirty patients (ASA I or II) undergoing TURP were studied. Spinal anesthesia was induced with bupivacaine. At the end of prostatic resection, the patients were randomly allocated into two groups. In one group (n = 15) the patients received furosemide 30 mg i.v., while in the other group (n = 15) they received glycerol 0.5 g/kg i.v. Blood samples were collected for measurements of osmolality, hematocrit, sodium and glucose concentration before anesthesia and after surgery. Urine output was also recorded after surgery in each group.
RESULTS: Plasma osmolality in glycerol group was higher than furosemide group at 30 min (295.3 +/- 10.6 vs. 283.8 +/- 5.6 mOsm/kg, p < 0.01) and 1 h after operation (294.9 +/- 8.7 vs 286.3 +/- 6.7 mOsm/kg, p < 0.01). Blood glucose was higher in glycerol group than that in furosemide group at 2 h after operation (195.6 +/- 121.9 vs 152.9 +/- 70.1 mg/dl, p < 0.05). Measured urine output was significantly greater in furosemide group at 30 min after operation (904.6 +/- 491.5 vs. 248.4 +/- 143.4 ml, p < 0.05) but was greater in glycerol group at 12 h after operation.
CONCLUSIONS: Since urine output is significantly less in glycerol group at 1 h after operation, glycerol is inferior to furosemide for preventing cystic clot retention after TURP. But glycerol may protect against water intoxication better for its merit of producing higher plasma osmolality.
