Diverticulum of the female urethra: a report of 50 cases.

In the last ten years 50 patients were treated for urethral diverticulum. In contrast to data in the literature the condition does not seem to be infrequent. The main symptoms are recurrent or long persisting disorders of urine flow often accompanied by loin pain during coitus. Beside the history, the diagnosis is based on anterograde or retrograde cystourethrography, urethroscopy , catheterization combined with vaginal exposure and bimanual examination. In treatment, diverticulectomy is a simple and successful method without complications, always relieving the long persisting or recurring complaints.

Paralimbic nephrotomy. Preliminary report.

This preliminary report discusses a method which unites the advantages of the surgical procedures introduced by Gil Vernet and Boyce for the transparenchymal removal of staghorn calculi. The significance of the length of the incision involving the parenchyma and the reduced thickness of the incised parenchyma are stressed. The urine collecting system (pyelocalyceal system) is explored through the renal pelvis making all the calyces well visible. Stones from the kidney can be removed and any anatomical alteration of the pyelocalyceal system is easily noticed. The worsening or improvement of the parenchymal function was assessed in gamma (ionization) chamber isotope studies and with intravenous urography. The restricted bleeding during the operation is attributed to the difference in blood supply between the limbus and other parts of the parenchyma.

[Transvesical prostatectomy and its complications].

Seven hundred and fifty transvesical prostatectomies are evaluated from the aspect of complications. The method is used for the removal of adenomas of more than 30 g weight. Consequently, it is considered important to exactly determine the size of the adenoma and its relation to the neighbouring organs. The decrease in the number of complications, as well as the shorter time of operation and of postoperative care are attributed to the surgical method modified by the authors which involves the use of synthetic multifilament continuous suture pulling together the edges of the base of the prostate, a three-bore catheter placed with its balloon into the bladder, washing of the bladder in a closed system, mobilization of the patient on the first postoperative day, application of easily absorbed synthetic threads and early removal of the catheter. In order to lower the number of complications, the importance of the properly chosen anaesthesia is stressed.

[Urological complications following surgical procedures and their management].

The urological complications of surgical interventions are discussed on the basis of the authors' clinical material collected over six years. Mainly fistulas and inflammatory complications occurred due to gynaecological operations performed by abdominal penetration. The possibilities and incidence of complications, as well as the diagnostic methods used for their detection and the applied therapies are reviewed. The importance of the proper choice of restituting surgical interventions is stressed. Complete anatomical and functional restoration and preservation of the organ are attempted. Attention is called to the importance and possibilities of preventing complications due to injuries. In the reduction of the incidence of urological complications after gynaecological operations, beside prevention, a close co-operation with the urologist is necessary as well as post-operative check-ups even in symptomless cases.

Innervation of the ureterovesical junction musculature of man.

The ultrastructure of the innervation of the human ureterovesical junction was studied. Three different nerve terminals were distinguished among the smooth muscle cells. 1. Nerve processes containing predominantly small granular vesicles (40--60 nm in diameter). 2. Other nerve fibres contained predominantly small round agranular vesicles (30--50 nm in diameter). 3. Processes with large granulated vesicles (80--120 nm in diameter). The first type may be adrenergic, the second cholinergic and the third may originate from the local nerve cells. The gap between the nerve fibres and muscle cells was 300 to 500 nm wide and no synaptic thickenings were observed. This suggests that the transmitter may influence several muscle cells, and the different nerve fibres may directly innervate the smooth muscle cells.

[Transurethral cryocaustic therapy of the prostate].

In nearly one year 64 transurethral cryocaustics were performed because of adenoma of the bladder neck (36 cases) and carcinoma of the prostate (28 cases). Essentially, the authors' method consists in freezing the necessary quantity of tissue and then "exploding" the destroyed cells by sudden heating. In contrast to other authors, the catheter is kept in the patient for 8 days. All of the patients belonged into the high risk group with complete retention. In the case of adenoma the results were good in 66%, fair in 22% and unsuccessful in 3% of the patients, while in 82% of the prostate carcinoma patients the results were good, 14% urinated with moderate residues and the operation was practically unsuccessful in 4%. Success meant an abolishment of the residue and a disappearance or moderation of pyuria. So far no complications have been encountered, but complications are believed to be unavoidable later. Cryocaustics is recommended in the case of patients with serious circulatory insufficiency or when, because of contra-indicated anaesthesia, no radical operation can be performed.

[Various aspects of surgical technics in renal-pole resection].

The authors give a survey concerning history and operation techniques, indications and use of the renal pole resection. They report on the method developed by them, by means of which the effect of haemostasis is increased, the loss of parenchyma is decreased and the patients may earlier be mobilized. Their experiences are based on the observation of 29 patients operated by means of the method described.

[New findings on the mechanism of micturation].

The nervous and muscular events in the start and process of micturation are analyzed. The experiments have shown that in the start of voluntary micturation the close anatomical link between the perineal cross-striated musculature and the neck of the bladder plays an important role. The fact that the straining of the vesicular musculature leads to the contraction of the detrusor is attributed a major importance in the maintenance of the process of urination. The thrusting force of the vesicular musculature transports the urine into the neck of the bladder where the pressure rises and the muscles of the bladder wall become stressed. The arising stimulation enhances the contraction of the detrusor and this process prevails up to the end of micturation. The experiments support the clinical findings, since they explain the different behaviour of central and partial cystoparalysis, thus the almost normal functioning of the reflex bladder and the atony of the "non-reflex" bladder.

Electronic bladder stimulation in spinal cord paralysis.

Authors performed electronic stimulation of the paralysed bladder that was attributed to various innervation troubles. For this purpose, they implanted 10 patients with stimulator Model PMS-3, each with 8 electrodes. In three cases, outside factors (like endocarditis, pyelonephritis aposthematosa, and progress of paralysis in the limbs) forced them to remove the stimulator. The other cases can be declared as successful, for complete bladder emptying has been obtained. The authors want to emphasize that patients with an implanted stimulator can dispense with an indwelling catheter thereby avoiding vesicoureteral reflux. The absence of recurrent pyelonephritis results in prolonged health. This new technique seems to be appropriate, especially in peripheric paralysis, while central paralysis connected with fibrosis of the bladder neck often requires additional surgical intervention, e.g. transurethral resection.

[Bladder stimulation of patients with spinal injuries].

Electric stimulation of the bladder through eight electrodes was performed in 7 patients suffering from innervation disturbances of various origin. In one case the device had to be removed because of endocarditis and sepsis after 8 months. In 6 cases the result was satisfactory as the patients were capable of emptying their bladder without catheterization. By abolishing vesico-ureteral reflux, recurrent pyelonephritis is eliminated, consequently life expectancy greatly improves. The method is believed to be suitable mainly in cases of peripheral bladder paralysis. In cases of central paralysis, the fibrosis of the bladder neck calls for additional interventions such as transurethral resection.
