Urodynamic profile in patients with Bladder outflow obstruction: Predicting outcomes

Abstract

Purpose: To access bladder functions or exact degree of outflow obstruction in patients undergoing TURP. Material and Methods: PF studies performed in 100 patients undergoing TURP between Aug 2012 to Aug 2014 before and 3 months after TURP. Results:The mean age of the patients was 70.29 (45-84) years. All patients enrolled in the study were having Serum PSA below 4 ng/ml with average being 1.3 ng/ml. Out of 100 patients, 42 presented with refractory retention and 58 with high AUA score. All patients with refractory retention had stable filling phase; Pdet@Qmax> 79 cm/H2O, with average Qmax -8ml/sec and AG No. >40. 35 patients were happy with outcomes of surgery. Out of 58 patients with high AUA Score, 29 patients were having predominant voiding symptoms, 17 patients were having predominant storage symptoms and 12 patients were having both storage and voiding symptoms. Patients with predominant voiding symptoms and both storage and voiding symptoms had urodynamically stable filling phase with high detrusor pressure and reduced flow rate. All of these had good surgical outcome.13 patients with predominant storage symptoms had detrusor over activity of which 3 were happy with outcomes of surgery; 7 patients had persistent LUTS, 3 lost to follow up. Conclusions: Patients having high AUA symptom score with predominant storage symptoms had detrusor instability (85%) and 45% were unhappy and hence in these patients PF studies could help us to counsel about the results of TURPKeywords:, ,
