[Spontaneous rupture of the kidney pelvis calix system--causes, diagnosis and therapy].

The symptoms, diagnosis and management of the spontaneous non-traumatic rupture of the urinary collecting system are described. It is important to distinguish this frank rupture of the diseased renal pelvis from extravasation due to pyelosinusal or fornical backflow. Most cases of the latter variety are caused by acute calculous ureteral obstruction and observed during intravenous pyelogram with abdominal compression. They can be managed conservatively. Frank rupture of the renal pelvis are caused by an acute obstruction in a collecting system affected by infection, chronic obstruction, calculous erosion or tumor and is usually of grave significance and requires early surgical intervention. If the therapy is adequate, the prognosis seems to be favourable and nephrectomy seldom necessary.

Results of surgical and conservative therapy on patients with nephrolithiasis and chronic renal insufficiency.

In a series of 264 inpatients with nephrolithiasis and chronic renal insufficiency, 159 received follow-up care between 1 and 14 years (4.3 years on the average) after primary hospitalization. 59 of these 159 patients had to undergo nephrectomy in the course of calculus disease. Follow-up examinations showed no deterioration in 60 patients and a further 64 showed clear symptoms of improved renal function. In 23 patients renal function deteriorated and 11 of them had to be accepted in chronic dialysis. Special emphasis is placed on the relevance of thorough metaprophylaxis after calculus removal. Stone analyses of patients with renal insufficiency showed a high share of infectious stones (struvite and carbonic apatite) as well as of uric acid calculi. For that reason especially these patients require an intensive follow-up treatment.

10,000 analyses of urinary calculi using X-ray diffraction and polarizing microscopy.

To make qualitative as well as semiquantitative analyses of 10,000 urinary calculi of large city population, a combined crystal-optical X-ray diffractometric method proved to be very useful. This combination goes to complement the advantages of polarization microscopy (with its minimal substance requirements, its proof limits of less than 1%, and its insight into stone texture) with those of X-ray diffraction (with its fast semiquantitative analysis and simple differentiation of all the stone components). About 30% of the calculi were found to have a monomineral composition. The most frequent types of calculi in our examination were: 33.2% whewellite/weddellite, 24.9% whewellite, 13.5% whewellite/weddellite/apatite, 7.0% struvite/apatite, and 3.9% uric acid/uric acid dihydrate.

[Hydrochlorothiazide in the metaphylaxis of recurrent calcium oxalate lithiasis].

The main indication for the application of Disalunil in the convalescent care of recidive calcium-lithiasis patients is renal hypercalciuria. Treatment with 50 mg Disalunil/d reduced the rate of recidivation by two thirds. Even during long-term application of this therapy over 3-7 years, side effects were slight and did not require any cessation of therapy.

[Spontaneous kidney parenchymal rupture--etiology, symptoms, diagnosis and therapy].

Spontaneous rupture of the renal parenchyma with perirenal hematoma occurs rarely. A review was made of 85 cases published in the literature, including 2 of our own. Tumors were the most common cause followed by vascular diseases of the kidney. The most common symptoms were an acute onset of flank or abdominal pain (65%), microscopic or macroscopic hematuria (43%) and signs of hemorrhagic shock (33%). In all cases a tender flank and/or mass were palpable. Urography reveals a mass, distorted collecting system and/or non-visualization of the kidney. Nephrectomy when possible should be performed expeditiously since conservative therapy is uniformly unsuccessful and life-threatening.

Urolithiasis after kidney transplantation--clinical and mineralogical aspects.

Urolithiasis is a rare complication following kidney transplantation. Experience with this complication in 6 of 426 transplantations performed from 1968 to 1979 is reviewed. The clinical symptoms are different from the disease in non-transplant patients. Three major predisposing causes for the development of calculi after kidney transplantation were found in our patients--urodynamic disorders following complications of the ureterovesical anastomosis, persistent bacteriuria and renal tubular acidosis and, less importantly, the presence of hypercalcemia and hypercalciuria as a result of secondary hyperparathyroidism. Crystal-optical and x-ray-diffraction studies contributed to the interpretation of the constituents and texture of the calculi and of the aetiological factors concerned.

[Distal form of renal tubular acidosis and nephrolithiasis].

The distal form of the renal tubular acidosis is a causal factor of the formation of phosphate calculi which is not tao be neglected. Pathophysiology, diagnostics and therapy of the renal tubular acidosis are described under the point of view of the metaphylaxis of urinary calculi. The paraclinical findings of 7 patients with distal renal tubular acidosis and nephrolithiasis and nephrocalcinosis, respectively, are discussed.

On the therapy of urolithiasis in chronic renal failure.

A resigning attitude in respect to patients suffering from nephrolithiasis and manifest renal failure is not justified anymore in view of the advances in diagnosis and therapy. During the period 1964-1975, at the urological clinic of the hospital Friedrichshain 188 patients suffering from nephrolithiasis and renal failure have been treated: 120 surgically and 68 conservatively. The operative-therapeutical conception is outlined. The pre- and postoperative hemodialysis therapy is described in detail and the different indications of hemodialysis according to the stage of renal failure are elaborated. Tabulated data demonstrate the fate of all surgically treated patients.

Allopurinol in the recurrence prevention of calcium oxalate lithiasis.

Since 1973 we have used allopurinol in the prevention and aftercare of recurrent urolithiasis. We give indications for the administration of allopurinol for patients with chronically recurring calcium oxalate lithiasis. Special attention is given to the urinary stone analysis as well as to metabolic disorders as for example hyperuricaemia, hyperuricuria or idiopathic hypercalciuria. In 15 patients with calcium oxalate lithiasis the stone/patient/year ratio could be decreased to 38%. In 19 patients with uric acid/calcium oxalate calculi or alternating stone formations from uric acid and calcium oxalate we succeeded in decreasing this ratio from 1.72 to 0.47 or 27%.

[Topographic phase analysis of urinary concrements using crystal-optic methods].

In the present paper was reported on the results of the topographic crystal-optic analysis of urinary calculi of 560 concrements. 59% of all urinary calculi had a different phase content in the nucleus and in the calyx. All frequent minerals of the urinary calculi could be proved in the nucleus of the calculus. It could be shown that nucleus and calyx may have a monomineral as well as a polymineral structure. It is referred to the importance of the topographic analysis of the urinary calculi for the metaphylaxis of the urolithiasis.
