Trabeculation of urinary bladder by ultrasound in patients with benign prostatic hyperplasia.
The aim of our study was to assess the prognostic value of trabeculation of urinary bladder assessed by ultrasound as an non-invasive diagnostic tool to diagnose the bladder outlet obstruction and prognostic factor to urinary retention and the need for surgery. Out of 171 patients 120 were with spontaneous voiding and other 51 were presented with acute urinary retention. 87 of them underwent surgical treatment immediately and other 17 underwent surgery during follow-up period 12 months. Ultrasound investigation revealed trabeculated bladder or with diverticula in 107 men and other 64 had non-trabeculated bladders. In 120 patients with spontaneous voiding 76 had moderate urinary symptoms (10 < I-PSS < 18) and other 46 had severe symptoms (18 < I-PSS < 35). 57 patients had the residual urine volume les that 100 cc and 63 had above that amount. 50 patients had decrease peak flow below and other 70 had Qmax more than 10 ml/sec. Using chi(2) test statistical analysis urinary symptoms and residual urine did not correlate with bladder trabeculation, though the low peak urinary flow Qmax highly correlated with bladder trabeculation (p<0.005). We observed high correlation between the bladder trabeculation and urinary retention (p<0.05); immediate indication for surgical treatment (p< 0.0001) and need for surgery during the one year follow-up (p<0.00019). Bladder Trabeculation may be helpful in differentiating between the compensated and decompensated stages of bladder outlet obstruction.
