Abstract

To describe a novel transurethral front-firing Greenlight bladder autoaugmentation for the treatment of bladder contracture and report initial clinical outcomes. Between April 2014 and August 2015, five patients diagnosed with contracted bladder were all refractory to conservative treatment and received novel transurethral autoaugmentation. CT scan and urodynamics examination were conducted before operation for disease assessment. Mucosal and muscular layers of bladder wall in fundus were incised vertically and horizontally with front-firing Greenlight laser to enlarge bladder capacity in the operation. Imaging examination and periodical urodynamics study were performed to evaluate the clinical outcomes of the procedure in postoperative follow-up. Transurethral front-firing Greenlight bladder autoaugmentation was performed successfully on all the patients. The mean operative time was 59 min (range 52-65 min) with no significant blood loss. Urodynamic parameters of these patients after operation improved significantly compared with those before operation. Average maximum cystometric capacity (Vmax) increased from 91.2 to 333 ml (p < 0.01), average maximum flow rate (Qmax) ascended from 12.6 to 18.62 ml/min (p < 0.01), and averag...Continue Reading
