摘要:

Large calculi were observed to pass spontaneously from both a true and a false ureterocele. Since the walls of the ureter in the false ureterocele are assumed to have normal muscular coats and the walls of the true ureterocele have been found to possess a normal number of muscle fascicles (which are however more thinly distributed), expulsion of the stone in both cases might be anticipated. Further, the size of the stone passed from the true ureterocele indicates that its orifice may be as distensible as that of the normal ureter, so that immediate instrumental or surgical intervention is not warranted.

摘要:

Urinary zinc, calcium, creatinine and osmolar excretion per 24 hours was measured in 21 healthy subjects and 49 patients with urolithiasis. Urinary zinc excretion in kidney-stone formers was lower than in healthy subjects, but the difference was not statistically significant. In healthy subjects, there was a normal relationship between urinary zinc excretion and urine volume, creatinine and osmolar excretion, which was not found, with some exceptions, in the groups of patients. There was no relationship between urinary zinc and calcium excretion in healthy subjects or in patients with normocalciuria or hypercalciuria. A possible role of relative hypozincuria in kidney-stone formation in patients with hypercalciuria and/or hyperoxaluria is suggested.

摘要:

The authors report on indications, operative technic and clinical experience with the so-called horned bladder (horn-like extrusion) with simultaneous re-implantation and submucosal placement of the ureter. In 6 years the procedure was successfully employed in 35 patients. As compared to the Boari flap-method, it is simple, the anastomosis is without tension, and there is lessened danger of reflux because of the submucous tunnelling of the ureteral end.

摘要:

The urinary complications of renal transplantation still menace the graft and often the patient’s life, occurring in almost 11% of cases. Since virtually all authors must often resort to uretero-vesical implantation, we have analyzed our complications in 100 instances of termino-terminal ureteroureteral anastomosis among the 120 transplantations we have done over the last 5 years.19 fistulas, 5 stenoses and 1 lithiasis have led to one or more reoperations. These complications had as their origin death by vascular ulceration and two nephrectomies of perfectly functioning transplants. In all three, one was dealing with fistulas, in which immunologic factors did not play a preponderant role etiologically. Apart from the fact that they were more frequent with kidneys from unrelated donors, one noted that the fistula in 2 cases appeared at a time of crisis of the transplant, that lesions with edematous and ischemic features at the end of the transplant’s ureter could have been recognized by endoscopy at the time of crisis, and that they totally disappeared with healing. Perforative ureteral and even pyelic lesions were identified at a distance from the anastomotic site and, without knowing the aspects of soft tissue rejection, certain ureteral features could bring it about. On the other hand, the sequelae of ureteroureteral reanastomosis, whether carried out for fistula or for stenosis, at a time when rejection becomes less frequent, are generally extremely simple. In fact, if this anastomosis, the most physiological, seems a bit more exposed to the danger of complications than the others, the complications seem less grave and repair easier. This is why we think termino-terminal ureteroureteral anastomosis should keep its place of choice, while more startling indications should perhaps be reserved for cadaver transplants, in any case, for non-related transpla

摘要:

Within seven years, 139 patients with multiple sclerosis or allied disorders were treated with transurethral resection for stenosis of the bladder neck. Six-month follow-ups were performed in 134 patients alive at that time. At the follow-up, one-quarter of the patients were practically symptom-free, and a total of three-quarters were improved. The results were best in the group without incontinence. However, among 99 patients with urge incontinence, more than one-third had become continent, and in another quarter the incontinence had decreased. Bladder-neck stenosis must be suspected in multiple sclerosis patients with difficulty in bladder emptying not referable to acute aggravation of the disease, and in patients with urge incontinence in whom drug therapy has not had a satisfactory effect.

摘要:

A new procedure for cystectomy in cancer of the bladder (and related diseases), which seems to be superior to all others proposed up to now, is presented. It consists of: (a) radical cystectomy; (b) annulment of one of the kidneys by tying tis ureter; and (c) implantation of the remaining ureter in the skin or in the rectum. The procedure is based on the polyuria with which the single kidney is forced to function and which effectively impairs the deposition of urinary salts in the catheter and in the pyelorenal cavities, the infection of urine and, when applicable, the resorption of urinary salts by the rectum. 13 cases treated in this way are presented: 11 with the ureter implanted in the skin and two with the ureter implanted in the rectum; the normal aspect of the defecated urine – when in feces absence – is emphasi

摘要:

The relationships between the hormone levels in urine and plasma before semicastration, before radiotherapy, and after radiotherapy were studied in four patients with seminoma. Pretreatment levels of estrogens were elevated in two patients. The operation and radiotherapy had only a small effect on estrogen excretion. In all patients, low testosterone excretion was observed preoperatively, whereas, the plasma testosterone values were normal. Under treatment, the latter values also decreased slightly. Due to therapy, the dihydrotestosterone concentration in blood also fell. In patients with reappearing metastases, progesterone blood levels demonstrated a tendancy to increase. The gonadotrophin picture could not be characterized by the Pregnosticon test.

摘要:

In this paper, the relationships between the hormone levels in urine and plasma before semicastration, before radiotherapy, and after radiotherapy were studied in five patients with malignant teratoma of intermediate type B and three patients with malignant trophoblastic teratoma. Estrogen levels were significantly elevated preoperatively in all cases of malignant teratoma of intermediate type B, and one out of three cases of malignant trophoblastic teratoma. A follow-up study on one patient with malignant teratoma of intermediate type B and on two patients with malignant trophoblastic teratoma confirmed the diagnostic and prognostic importance of estrogen determinations in patients with testicular tumours. No clear-cut picture was obtained concerning testosterone excretion and blood testosterone levels. Whereas semicastration in some patients resulted in a fall of the plasma testosterone, other cases demonstrated significant elevated blood and urine testosterone levels. The possible influence of gonadotrophins – either produced by the tumour tissue or in increased amounts by the pituitary – on the steroid hormone content is discussed. Of practical importance is the finding that, even in malignant trophoblastic teratoma, the Pregnosticon test was not always sensitive enough to give a positive reaction. On the other hand, the quantitative HCG determination in blood and urine is of considerable importance for the differential diagnosis of the respective type of tum
