The choice of operative techniques applicable in urethral strictures and obliterations is rather great today. The author holds that procedures that may entail bladder hypotonia,
pyelonephritis
,
nephrolithiasis
, prostatitis, impotence, especially in young patients, should be rejected as ineffective. These complications often result from ignorance of perineal anatomy, erroneous choice of surgical policy leading to bouginage. To avoid it, the surgeon is advised to employ two-stage urethral reconstruction according to B. Johanson. The procedure, proposed in 1950, implies usage of plastic material obtained from penile and scrotal skin. The original variant of the procedure has the disadvantage of confinement only to urethral strictures. We use two new variants of Johanson operation which can abate not only strictures, but obliterations as well. The experience of 1-26-year follow-up indicates feasibility of our modified operations in multiple strictures in combination with other surgical interventions, in urethrorectal and perineal fistulas and in pediatric surgery.

The role of antibodies to Tamm-Horsfall protein in the diagnosis of acute
pyelonephritis
was studied. Antibodies to Tamm-Horsfall protein were also determined in a group of normal subjects. Patients with acute
pyelonephritis
were divided into subgroups according to the concurrent presence of vesicoureteral reflux or
nephrolithiasis
. No statistically significant differences (p > 0.05) were observed for any class of antibodies (IgG, IgA and IgM) between the groups of healthy subjects and patients with acute
pyelonephritis
, regardless of the presence or absence of vesicoureteral reflux or
nephrolithiasis
. Values for different antibody classes showed that IgM antibodies were the most abundant in all the groups examined. A difference in the values of IgM relative to IgA and IgG antibodies was found to be statistically significant in the patient group only (p < 0.05). In patients with vesicoureteral reflux, there was no statistically significant difference (p > 0.05) between the values of IgM and of other antibody classes. In these patients, however, the highest values of all the three antibody classes were obtained, although these differences were also not statistically significant (p > 0.05). The results pointed to the need of further studies of the role of antibodies to Tamm-Horsfall protein in the diagnosis and pathogenesis of tubulointerstitial nephritis.

Lipid peroxidation (LPO) activity has been analyzed in homogenates and microsomes of cortical samples obtained intraoperatively from the kidneys of 33 patients. Of them, 21 patients had mild, moderate or severe
pyelonephritis
or
nephrolithiasis
. Unaffected cortical tissue from renal carcinoma patients was used as control. LPO activity was judged by basal level of malonic dialdehyde (MDA) and MDA growth in the homogenate and microsomes following initiation of ascorbate-dependent LPO. Activation of LPO was registered in patients with moderate disease with active inflammation. They also exhibited greater MDA basal levels and rapid MDA increase in response to in vitro initiation of ascorbate-dependent LPO simultaneously with attenuation of endogenous antioxidant defense. In severe
pyelonephritis
and
nephrolithiasis
with drastic deficiency of renal function LPO activity was low and nonresponsive to stimulation either by ascorbate or Fe+2. This is probably due to lack of the substrate after massive death of renal cells. Enhancement of LPO activity in patients with
pyelonephritis
or
nephrolithiasis
against functioning kidneys may appear responsible for destruction of renal tissue.

Renal carcinoma and urolithiasis combine rather rarely. Postnephrectomy patients often consult the urologist when the condition is serious because of complications resultant from uroliths in the contralateral kedney. In view of solitary kidney, progressive chronic
pyelonephritis
, associated chronic renal failure surgical treatment of the condition becomes risky and necessitates individual approach to choice of therapeutic policy and definition of indications to urolithiasis treatment in patients after nephrectomy for renal carcinoma. This includes the decision whether to perform
nephrolithiasis
before or after nephrectomy and whether to attempt any surgery in the absence of urolithiasis clinical symptoms.

Although pancreatitis and subphrenic abscess frequently cause pleural effusion, renal disease rarely does so. We report a case of a young patient who presented with pleural effusion due to
pyelonephritis
and renal outflow obstruction secondary to
nephrolithiasis
. The effusion and the initial absence of urinary abnormalities resulted in delay in diagnosis and initiation of appropriate therapy.

The author has estimated levels of malonic dialdehyde (MDA) indicative of activity of membrane phospholipid peroxidation activity, basal and true (in incubation in the culture containing glomeruloform antibiotic alameticin) Ca-ATPase activity in microsomal fraction isolated from cortical tissue of functioning kidneys obtained intraoperatively from 26 patients. 12 samples of cortical tissue obtained from uninvolved parts of the kidneys affected with carcinoma served as control. 14 samples were obtained from the tissue of functioning kidneys affected with
nephrolithiasis
and active chronic
pyelonephritis
. The investigations show elevated MDA levels, enhanced basal in reduced true Ca-ATPase activity of microsomes from the kidneys of patients with
nephrolithiasis
and active chronic
pyelonephritis
compared to control. It is suggested that high basal against low true Ca-ATPase activity of renal microsomes may be explained by increased permeability of renal membranes for Ca2+ under activation of lipid peroxidation in active chronic
pyelonephritis
and
nephrolithiasis
.

Arterial hypertension is frequent among chronically dialyzed patients. The kidney obviously plays a major role in arterial blood pressure control. There is a large number of experimental data emphasizing different factors (in addition to renin important in renal hypertension prognosis) such as: sodium balance, angiotensin, etc [1-8]. Sympathetic activity disorders or lack of vasodilatory prostaglandins and quinine may also play a certain role. In uremic patients peripheral arteriolar resistance is increased, unlike normotensive uremic patients or those who prove to be normotensive upon clinical examinations [8, 11-15]. Hypertension occurs in approximately 80% of patients with chronic renal failure, producing a number of complications primarily affecting the CNS and systemic circulation [5-8, 10, 11, 13]. The study concerned patients on chronic dialysis, with a male to female ratio of 69.9%:32.1%. In most of them the underlying disease, which caused chronic renal failure, was glomerulonephritis (60.0%), then
pyelonephritis
(17.0%) and nephrosclerosis,
nephrolithiasis
, polycystic kidney and, finally, renal tumours. The effect of permanent haemodialysis during the first year of treatment, was efficacious on hypertension in 1704 (65.1%) patients; in 672 (25.7%) patients therapeutical effects were achieved by dialysis and antihypertensive drugs, while in 240 (9.2%) subjects there was no improvement. General observations suggest that two types of arterial hypertension persisted in patients with chronic renal failure: volume-dependent arterial hypertension which is more frequent (90-95%) among haemodialyzed patients and renin-dependent hypertension. Such findings are of utmost importance indicating that hypervolaemia is one of the major factors in the development of arterial hypertension in patients with chronic renal failure, with renin playing the secondary role. Salt-free diet should be used in the treatment of arterial hypertension for years, a well conducted haemodialysis is highly effective in the control of arterial hypertension among these patients. In our series of patients dialysed three times a week; normalization of blood pressure was faster with lower incidence of hypertensive crises during haemodialysis and with few complications. Water and sodium excess was reduced by frequent haemodialyses and sudden changes in electrolyte, hydrostatic and other metabolic effects were minimized. Increased values of plasma renin activity were observed in a small number of patients. Ultrafiltration is insufficient for normalization of blood pressure. Hypertensive crises were frequent in these patients. Their response to medicaments such as methyldopa, beta-adrenergic blockers or other antihypertensive drugs, was good. Severe changes in blood vessels, especially in fundus oculi blood vessels were frequent in these patients. The life of hypertensive glomerulonephritis patients was especially endangered (graphs 1-6). In addition to the mentioned factors arterial hypertension during haemodialysis may also be of cardiac origin, including increase in cardiac output due to arteriovenous anastomosis, disequilibrium syndrome, changes in osmotic gradient of both extra- and intracellular spaces with resultant arteriolar wall oedema, erythrocyte amount, hypoxia, composition of dialysis fluid (sodium concentration), plasma osmotic pressure, metabolic acidosis and other factors. More recently, natriuretic hormone has also been indentified as a cause of vascular refraction. Peripherial arteriolar resistance as a cause of arterial hypertension among uremic patients must not be forgotten, because the genesis of arterial hypertension in patients with chronic renal failure is multifactorial. The highest percentage refers to volume-dependent arterial hypertension, whereas the percentage of other aetiologic factors is lower. Haemodialysis enables the normalization of blood pressure in most of hypertensive patients.

The medical records of out-patients and in-patients served as the source of information for the incidence of nephrourological diseases, within the period 1983-1992. Cancer Registry and other appropriate registries of central Serbia were analysed, too. Mortality data were taken from the Republic Institute of Statistics. Descriptive method was used in epidemiological analysis. The highest incidence rates of kidney diseases were in central Serbia (59.6%), and the lowest in Kosovo and Metohija (40.2%). The most frequent were
nephrolithiasis
(26%), bladder and urethral diseases (20%) and
pyelonephritis
(17%). Mortality rates were highest for nephrosis and nephritis (13.7%). Men died more frequently due to malignant tumours of the bladder (4.9%) and kidney (2.3%) than women (1.2% and 1.6%). Unsteady quality of original data referring to constitutional parts of Serbia interfered with total comprehension of the epidemiological situation.

Successful disintegration of the calculus in
nephrolithiasis
patients is impossible without normalization of the upper urinary tracts urodynamics in dyskinesia. We employ combined treatment with high-selective beta-2-adrenomimetic hexoprenalin (hinipral) to improve migration of the concrement fragments and therefore to prevent ureteral occlusion, acute
pyelonephritis
and renal colic. Hexoprenalin (hinipral) is taken 6 tablets a day or intravenously in drops (5 ml per 100 ml of saline) 3-5 days before and for 10-12 days after extracorporeal shock-wave lithotripsy. Adjuvant use of hexoprenalin in combined treatment of
nephrolithiasis
complicated by ureteropelvic dysfunction allows effective conduction of lithotripsy.

Recently, drug polyuria has found wide application in diagnosis and treatment: to detect latent urinary insufficiency, to assess functional performance of the contralateral (unaffected) kidney in
nephrolithiasis
and calculous
pyelonephritis
, to stimulate elimination of fragments of the disintegrated concrement, to check up suture impermeability after surgical repair of the urinary tracts, to outline afunctional zone in hydronephrosis. Clinical experience gives grounds for use of saluretics at certain stages of pyelolithotomy for mobilization of intrarenal pelvis and its dissection, removal of the calculus and subsequent suturing of the intrarenal pelvis. Therapeutic polyuria can also facilitate ureterolithotomy.
