Ureteroneocystostomy without dissection of the submucosal tunnel

A technique of ureteroneocystostomy with fixation of the ureter to the bladder musculature denuded from the mucosa was studied in dogs. The intravesical portion of the ureter shrank to half its original length after the operation. This portion preserved its muscular structure and was overgrown by the bladder mucosa to more than half its circumference. The submucous canal thus formed for the ureter prevented reflux in every animal. The technique avoids the formation of strictures. It is recommended if direct dissection of a submucous canal is impracticable.

[Serum acid phosphatase levels following prostatic massage (author's transl)]

We find an elevation of serum acid phosphatase levels 5 min after prostatic massage in only 10% of patients with prostatic adenoma. This increase is caused by stored prostatic secretion being pressed into the blood vessels. 60 min later these serum levels decrease. With some other patients a slower increase of phosphatase levels occurs; this increase, however, lasts for hours. This kind of increase is caused by prostatic fluid being forced into the interstitium where it is slowly absorbed. A combination of both kinds leads to a curve with two peaks; this could be demonstrated in two cases. No difference was seen in reaction of total acid phosphatase and prostatic phosphatase levels. The increase of phosphatase levels following prostatic massage was no sign of prostatic carcinoma.

[Perineal and transrectal needle biopsy of the prostate (author's transl)]

On 254 biopsies of the prostate with the tru-cut needle the approach was either rectal or perineal depending on even or uneven dates of birth. The rectal approach showed wrong negative results a little more frequent than the perineal approach. Feverish complications were 6 times more often by rectal than by perineal approach. Additionally the rectal biopsy was complicated by serious bleedings out of the hemorrhoidal vessels or periprostatic veins. Based on the investigations you should chose the perineal approach as the routine method and use the rectal biopsy only for special indication.

[The position of the renal pelvic axis in the infant (author's transl)]

The position of the longitudinal axis of the renal pelvic system is of special significance in the diagnosis of renal pelvic reduplications, horseshoe kidneys and space occupying processes of the kidney. The present study of 143 normal infant urograms shows that the angle between the axis of the renal pelvis and the axis of the vertebra is dependent on age. While in the newborn a negative angle is a common finding, during adolescence the axis approaches the position we usually find in the adult.
