30 patients with urethral strictures treated with internal urethrotomy with the Sachse urethrotome were followed from 2-25 months postoperatively. Reexamination included retrograde urethrography and flow studies. One half of the patients were fully satisfied, one fourth reasonably so, whereas the remaining patients were dissatisfied. Urethrography and flow study revealed a considerably higher rate of recurrence than the clinical results.
The problems about the value of excretory urography as a preoperative diagnostic examination in patients with benign hypertrophy of the prostate are discussed. On the basis of IVPs, renal function, and absence of hematuria and/or infection in 500 consecutive patients who were to undergo prostatic surgery, it is concluded that IVP is a superfluous examination. In patients with impaired renal function (Se-creatinine greater than 1.5 mg%) IVP showed abnormalities in 41.3%. In patients with normal renal function and urinary tract infection IVP revealed abnormalities in 20.6%. In patients with normal renal function and microscopic hematuria IVP showed abnormalities in 19.2%. It is thus concluded that IVP should be undertaken in patients with impaired renal function (Se-creatinine greater than 1.5 mg%) and may be considered in patients with normal renal function with hematuria or infection.

In 20 male patients with urethral strictures, urethral pressure profile was compared with retrograde urethrography. There was good accordance between the two methods with only minor discrepancies in multiple or very distal strictures. Urethral profile did not provide more exact information than did urethrography.
