Bladder replacement after radical cystectomy using detubularized right colonic segment.

Bladder replacement after radical cystectomy offers the cancer patient the possibility of restoration to a functional level not possible with the standard means of urinary diversion. Herein we present our experience using a detubularized right colonic segment to create functional reservoirs in 2 male patients and a continent reservoir in a female patient. Cystometric analysis reveals capacious reservoirs, low basal pressures, and a tendency toward pressure spikes at higher filling volumes. All 3 patients are continent at volumes up to 400 cc with preservation of the upper urinary tracts and the absence of reflux. We believe the simplicity of this technique and the encouraging results will contribute to more widespread application of continent and functional reservoirs.

Diagnosis of acute testicular torsion using radionuclide scanning.

We analyzed retrospectively 99mtechnetium scrotal scan findings in 37 patients with acute scrotal pain. Correlation between scan interpretation, and either surgical findings and/or final clinical diagnosis revealed an accuracy of 89 per cent. Only 1 false negative and 3 false positive results were recorded. Scan data revealed a positive predictive value of 75 per cent, negative predictive value of 96 per cent, sensitivity of 90 per cent and specificity of 89 per cent. An inter-institutional observer study also was conducted to assess reliability of the scan, resulting in an 88 per cent agreement. The testicular scan has been found to be an accurate and reliable method to distinguish between epididymo-orchitis and testicular torsion.
