Hemodynamic Evaluation of Varicocele Using 99mTc-RBC Venography / 대한비뇨기과학회지

ABSTRACT

PURPOSE: To evaluate the hemodynamic status of varicocele, 99m Tc-RBC venography was performed in 29 varicocele patients and 10 normal controls from January to July 1996. MATERIALS AND METHODS: The mean age of varicocele patients was 23 years old and of normal controls was 27 years old. Among 29 varicocele patients, 26 had varicocele in left side and 3 had in both side. In unilateral varicocele group. 2 cases had grade I, 8 cases had grade II and 16 cases had grade III varicocele. In bilateral varicocele group, all had grade III in le% side and grade II varicocele in right side. RESULTS: The mean+/-SD of left to right radionuclide uptake ratio in pampiniform plexus during resting and Valsalva maneuver state was 1.01 +/-0.041 and 1.05+/-0.051 in normal control, 1.05+/-0.021 and 1.101 in varicocle grade I, 1.21+/-0.191 and 1.21 +/-0.121 in varicocele glade II, 1.60+/-0.631 and 1.27+/-0.181 in varicocele grade III, 1 18+/-0.061 and 1.26 in bilateral varicocele. As varicocele grade be higher, the mean left to right radionuclide uptake ratio be larger during resting and Valsalva maneuver state. CONCLUSIONS: 99mTc-RBC venography can quantify the hemodynamic state of varicocele so we suggest that it is useful as a method of diagnosis and follow up in varicocele patient.
