[A critical review of the variations in size of the kidney caused by increased diuresis in hypertensive patients (author's transl)].

The authors studied the validity of Wolf and Dorph's test (increase in size of the kidney with increased diuresis) performed during intravenous urography in hypertensive patients. The technical procedure is described, and the results reported: 1 032 kidneys were measured, of which 84 had been also examined by arteriography. The results are analyzed and compared to those obtained after the standard method of early consecutive films, with the following conclusions: -- the test is not as valid as is suggested by the authors who described it; -- the information supplied by the standard method is more consistent and precise; -- the results of these two series are not completely superimposable; -- that even if Wolf and Dorph's test can sometimes supply useful information, it must not be relied upon completely.

[Urinary lithiasis after renal transplantation. 9 cases (author's transl)].

Nine cases of urinary lithiasis following renal transplantation are reported. They differ from 15 cases in the literature in their development late after transplantation and in that no relation with hyperparathyroidism could be clearly demonstrated. We emphasise the difficulty of the clinical and radiological diagnosis of this little-known complication. The course is essentially similar to that in non-transplant patients with lithiasis.

[Long-term survey of renal transplant preserved with Collins solution (author's transl)].

Collins solution is one of the world methods used for kidney preservation. A long term survey of transplanted kidneys thus preserved has never been reported. Clinical, biological, radiological and pathological data collected from 225 cadaver kidney tranplantations were analysed according to the total ischemic time (T.I.T) groupe I: TIT less than or equal to 12 hours, groupe II: TIT from 12 to 30 hours). No difference could be demonstrated between the two groups whether considering the percentage of immediate function, the serum creatinine level which was normal up to two years, the incidence of abnormal blood pressure, the pathological changes on routine biopsies performed at 6 months and 2 years and arteriographic features at 2 years. A better graft survival rate was consistently found at 6 months one year and 2 years when TIT was between 12 and 30 hours. This could be related to the higher indicence of well matched kidneys in this group of patients. The efficiency of exchange programs for compatible kidneys is thus emphasized.

Biologic, pathologic, and radiologic studies of cadaver kidneys preserved in Collins' solution.

Collins' solution is one of the world-wide methods used for kidney preservation. A long-term survey of transplanted kidneys thus preserved has never been reported. Clinical, biologic, radiologic, and pathologic data collected from 225 cadaver kidney transplantations were analyzed according to the total ischemic time (group 1: TIT less than or equal to 12 hr; group 2: TIT 12-30 hr). No differences could be demonstrated between the two groups, whether considering the percentage of immediate function, the serum creatinine level that was normal up to 2 years, the incidence of abnormal blood pressure, the pathologic changes on routine biopsies performed at 6 months and 2 years, or arteriographic features at 2 years. A better graft survival rate was consistently found at 6 months, 1 year, and 2 years when TIT was between 12 and 30 hr. This could be related to the higher incidence of well-matched kidneys in this group of patients, thereby emphasizing the efficiency of exchange programs for compatible kidneys.

Renal clubbing and scarring in adults: a retrospective study of 110 cases.

A urographic pattern of renal clubbing and scarring was found in 182 scarred kidneys of 110 adult patients. Homolateral vesicoureteric reflux was demonstrated by reliable techniques in 90/135 scarred kidneys. Urinary tract infections occurred in 75 patients. Hypertension developed in 20 patients with normal renal function and was not related to the extent of scarring. Chronic renal failure occurred in 30 patients with diffuse bilateral scarring. Four patients showed histologic changes of chronic pyelonephritis. Two hypertensive patients had a typical histologic pattern of Ask-Upmark kidney (segmental hypoplasia). Development of renal scars in adulthood was demonstrated in 2 cases.

[Results of radiological studies of prostate lesions in patients with urinary tract tuberculosis (author's transl)].

The authors have reviewed the case-reports of 160 patients with urinary tract tuberculosis in whom a complete radiological examination of the lower urinary tract had been performed. They analyze the frequency and significance of any prostatic lesions and describe the most effective investigational procedures for demonstrating such lesions. They were observed in about 50% of patients as opacification of the prostatic cavities, and can be clearly demonstrated in the large majority of cases by micturition cystography after intravenous urography, provided a satisfactory technique hs been used. In those cases where intravenous urography does not permit an effective micturition study, retrograde opacification is necessary, preferably by suprapubic cystography, and in some well-defined cases, by retrograde uretrography. The search for any prostatic affection is not a t a speculative study as it can explain some of the symptoms presented by the patient, and enable specific therapy to be prescribed.

[Value of radiological investigations in patients with dysuria after prostatic adenomectomy (author's transl)].

Dysuria is a relatively frequent complication after prostatic adenomectomy. The authors review 107 patients with this complication and demonstrate that radiological investigation, including a micturition study, preferably after IVU, shows the presence of an obstructive cause for the dysuria in the vast majority of cases (92.5%). There are two main types of obstructive lesion: - parietal stenosing lesions, - compression lesions. - The most frequent parietal stenosing lesions, apart from those of the bladder neck, are urethral stenoses. - Stenoses with total compression of the capsule are often the cause of severe dysuria. - Localized compression of the capsule and urethral stenosis usually cause only moderate dysuria. - An irregular lacunar image should suggest cancer of the prostate.
