Outcome of Transurethral Vaporisation of Prostate in Small Volume Prostate: A prospective observational study

Background Benign Enlargement of Prostate is common in aging men. Transurethral vaporisation of prostate is one modality of minimal invasive management of benign enlargement of prostate. This study assesses the efficacy and safety of transurethral vaporisation of prostate in small volume prostate. Objective To assess the efficacy and safety of bipolar plasma vaporisation of small volume prostate (Prostate Volume less than 40 grams). Method A total of 40 patients with prostate volume less than 40 grams and indications for operative management of benign enlargement of prostate were included. Patients with prior prostate surgery, urethral stricture surgery, presence of vesical calculus, urethral stricture and neurogenic bladder were excluded. Preoperative prostate size was assessed by transrectal ultrasonography. Comparison of preoperative and postoperative hemoglobin, sodium, international prostate symptom score and maximum flow rate was done. Perioperative complications were documented. Result The mean age of patients was 66.88 ± 9.09 years and the mean size of prostate was 32.52 ± 4.66 grams. Significant improvement in IPSS (preoperative 22, postoperative 9) and Qmax (preoperative 8.4 ml/min, postoperative 18.5 ml/min) was noted. There was significant drop in hemoglobin (p < 0.001) but no patients required blood transfusion. There was significant drop in sodium (p < 0.001) but no patients developed transurethral resection syndrome. Most complications were Clavien grade I. Two patients required recatheterization and all were catheter free on follow up. Two patients developed urethral stricture. Conclusion Bipolar transurethral vaporisation of Prostate is effective and safe treatment option for prostate volume less than 40 grams.
