[Extracorporeal shock-wave lithotripsy--beginning of a restructuring in the treatment of urinary calculi?].

After 31/2 years experiences with extracorporeal shock wave lithotripsy (ESWL) 852 patients have been treated. Because of the significant expansion of indications for ESWL from 15 to 70% of unselected stone formers, a permanent decrease of surgical stone removal can be expected, when ESWL availability is more sufficient. This may cause a change in the urological routine management of stone disease.

[The value of hypothermia methods in operative stone removal].

In spite of the possibility of using ultrasound for identification of stone fragments and vascular localisation, it is still necessary to clamp the renal vascular pedicle in selected cases. In situ perfusion achieves a nearly complete restoration of renal function, but requires a more sophisticated technique and preoperative planning. Surface cooling on the other hand is universally applicable and can be used during surgery, when unforeseen clamping of the renal pedicle is needed.

[Expansion of extracorporeal shock were lithotripsy by auxiliary methods].

With the introduction of the ESWL, this non-invasive form of treatment has proved itself to be an alternative to surgical renal stone therapy. The increasing application of auxiliary methods has results in a vast extention of the indications for ESWL-monotherapy. Therefore, presently, practically all patients with urolithiasis can be treated non-invasively, where previously, surgery had to be performed.

Shock wave treatment for stones in the upper urinary tract.

The authors report on their clinical experience in the use of extracorporeally generated, focused shock waves in the treatment of stone disease in the upper urinary tract. Generation of shock waves, arrangement of equipment, treatment, results, and indications are discussed.

[Microsurgical penis replantation following self mutilation].

Although amputation of the penis is a rare problem, a complete reconstruction of all penile structures should be attempted in one stage. This way the best chance for full rehabilitation of the patient can be achieved. A microsurgical reimplantation with microsurgical sutures of arteries, veins, nerves and urethra after total amputation of the penis is reported. Eight months after surgery normal appearance and function, including a good urine flow and absence of urethral stricture, capability of erection and nearly normal sensitivity, was found.

First clinical experience with extracorporeally induced destruction of kidney stones by shock waves.

We performed extracorporeally induced destruction of kidney stones on 72 patients. No complications have resulted from the tissue exposure to high energy shock waves. Clearance studies before and after the shock wave treatment indicate no changes in renal function. The method was used successfully in all patients with stones in the renal pelvis. In none of these patients was an open operation required. Two patients with ureteral stones also were treated with shock waves but had to be operated upon because of insufficient destruction of the stone.

[Limitations and hazards of palliative renal tumor embolization].

Today the indication for palliative embolization of inoperable renal carcinoma is more restricted than several years ago. Reviewing 31 own palliative occlusions of the renal artery in 29 patients over a period of 5 1/2 years two main reasons for this attitude are presented: 1. Because of collateral or parasitic vascular supply of kidney tumors the occlusion of the renal arteries only results in a retarded tumor growth rate and does not seem to prolong patient survival. 2. the "postembolization syndrome" after tumor occlusion has a relatively high complication rate and lethality (20% serious side effects, 3% deaths directly related to embolization). Therefore embolization of inoperable renal carcinomas is justified only in patients whose remaining lifetime can be alleviated by this measure. Certain indications are: massive hematuria, severe local pain due to the tumor and life endangering endocrine tumor activity, e.g. hypercalcemia. Uncertain indications such as recurring but not perilous hematuria causing progressive anemia and refusal of tumor surgery should be carefully balanced against the hazards of embolization.

[Organizational and technical aspects of organ removal].

The only efficient way to obtain adequate numbers of kidneys for transplantation is to perfect the technical and organisational method or organ harvesting. Careful attention to the details of organ procurement is as essential to the outcome of the transplantation as the procedure itself. To obtain optimal results, an effective collaboration between the central and peripheral hospital is necessary. A mobile medical and surgical team, coming from the central hospital for donor procurement was found to be most effective. Success in a major transplantation program requires continued improvement in the relationship between peripheral hospital physicians and the central transplant unit.

Extracorporeally induced destruction of kidney stones by shock waves.

High-energy shock waves were used to disintegrate kidney stones in dogs and man. In 96% of 60 dogs with surgically implanted renal pelvic stones, the fragments were discharged in the urine. The same effect was achieved in 20 out of 21 patients with renal pelvic stones. In the twenty-first patient, a staghorn calculus was broken up to facilitate surgical removal. 2 patients with upper ureteric stones also received shock waves, but their stones had to be removed surgically; in 1 of these the stone had been embedded in the ureteric wall by connective tissue. The procedure can in many cases be done under epidural instead of general anaesthesia. Side-effects consisted of slight haematuria and, occasionally, of easily treatable ureteric colic. They were probably due to passage of fragments down the ureter. Disintergration of kidney stones by shock waves seems to be a promising form of treatment that reduces the need for surgery.

Mitigation of hyperacute rejection by antilymphocyte globulin (ALG).

In HR, primarily humoral immunologic factors trigger a sequence of events that finally destroys the transplanted organ. Unspecific trapping of WBC diminishes the RBF, especially in the first compartment--the cortex. Pretreatment with ALG is able to suppress this cellular participation partially, thus postponing the stop of RBF without preventing the influence of humoral factors on the graft. As shown by pathologic and functional criteria recorded for 8 hr, an exclusive measurement of total RBF does not reflect an inhibition of the course of HR.
