Ureteral involvement secondary to diverticulitis of the colon.

Ureteral involvement in instances of diverticulitis of the colon is quite unusual. The left ureter is more commonly involved but right sided and bilateral instances have been reported. There are three types of involvement: fistula, stricture and compression, the latter being the most frequent. Roentgenographic characteristics and the effects of various treatment modalities on the affected ureter are presented herein.

A gastrin gene is expressed in both porcine pituitary and antral mucosal tissues.

By employing S1 nuclease mapping of total RNA isolated from porcine cerebral cortex, cerebellum, hypothalamus, pituitary, kidney, liver, pancreas, intestine, and antral mucosa, we have investigated gastrin gene expression in these tissues. Our results show that a gastrin gene is expressed only in the antral mucosal and pituitary tissues. Based on the amount of gastrin specific probe protected from S1 nuclease digestion in the presence of a given weight of total RNA, the amount of gastrin mRNA present in pituitary is approximately 330 times lower than in antral mucosa. These findings help establish the tissue distribution of gastrin gene expression.

Sonographic biometry in obstructive uropathy of children: preoperative diagnosis and postoperative monitoring.

Renal sonography was performed in 92 children with obstructive uropathy or vesicoureteral reflux preoperatively and at follow-up. Renal volume and the anteroposterior diameter of the renal pelvis proved to be the most reliable morphometric criteria for objective sonographic staging and follow-up of urinary tract obstruction. If transient obstruction occurred after uncomplicated antireflux ureterovesico-plasties (n = 41), it lasted at most 4 weeks. Kidneys with transient postoperative ureterovesical junction obstruction (n = 21) reverted to normal sonographic pattern within 4 weeks following ureteral reimplantation. In cases of ureteropelvic junction obstruction (n = 30), it took up to 6 months for the majority of kidneys to present almost normal sonographic findings. Sonographic biometry and the knowledge about the uncomplicated postoperative course render postsurgical monitoring easier and more reliable.

Granulomatous prostatitis. Special reference to radiologic findings.

Cystourethrography was performed in 2 patients with nonspecific, noneosinophilic granulomatous prostatitis. Lengthening of the prostatic urethra was noted essentially in the inframontane portion, thus differentiating it from benign prostatic hypertrophy. The widening in the prostatic urethra differentiates it from carcinoma of the prostate.

Immunological observations following vasectomy.

Lymphocytotoxic antibodies (LCA) against panels of normal lymphocytes and leukemic B-cells were demonstrated in vasectomized men. Since vasectomy is known to induce antibody formation to spermatozoa, the demonstration of these lymphocytotoxic antibodies may be related to antigenic constituents of spermatozoa such as HLA or B-cell alloantigens. Long term follow-up is needed to clarify the clinical significance of these antibodies.

Roentgenographic evaluation of nephroptosis.

Vertical and medial nephroptosis was assessed on 60 consecutive excretory urographic examinations. Ptosis, both vertical and medial, was seen more commonly in females, and vertical ptosis was more frequent than medial ptosis. In our series there was no significant evidence of predominance on the right side. Dietl crisis, nausea, vomiting, hypotension, oliguria, or orthostatic hypertension were not encountered. Nephroptosis was mostly asymptomatic. In those patients with symptoms, lumbar pain was common and could be either aggravated or relieved by change in position. A new sign, paradoxic displacement, is described. This could be of value to the surgeon and radiotherapist in evaluating enlargement of a huge abdominal mass - a difficulat task to assess clinically.

Various applications of corpus cavernosography.

The authors believe corpus cavernosography is an important aid in the evaluation of metastatic lesions, priapism, impotence, atrophy and fibrosis of the penis, and trauma to the penis. By visualizing the emptying of the contrast material from the cavernous spaces into the veins draining the penis, it is possible to assess the length of time that the contrast material remained in the organ.
