A summing-up is given of the ureterocystoncostomies performed, between 1956 and 1966, in 86 patients in author's Department. Indications, technique and operatory results are discussed, in comparison with the relevant data in the literature.

Serum renin concentration (SRC) was determined in 97 hypertensive patients under basal conditions and during stimulation of renin secretion. Renin secretion was stimulated by upright posture and by either of the following means: (a) diet containing 20 mEq Na/24 hours for 3 days; (b) 300 mg i.v. diazoxide injections; (c) oral ingestion of 80 mg furosemide; (d) oral hydrochlorothiazide (HCT), 25 mg twice daily for 3 days. HCT was used in 6 patients previously treated with diazoxide and in 8 patients previously treated with furosemide. Using pairs of basal and stimulated SRC determinations, the patients could be classified as high, normal, or low renin hypertensives. HCT proved to be the most convenient stimulus as far as efficacy, reliability and the patients' tolerance were concerned, and compared well with sodium restriction.

Autoimmune pancreatitis is a rare form of pancreatitis characterized by responsiveness to steroid therapy and an often relapsing disease course. The mainstay of therapy is oral corticotherapy. Associations of interstitial nephritis with various autoimmune disorders have been described. We hereby report the case of a 69-year-old Caucasian man with a 2-year history of autoimmune pancreatitis, who presented with impairment of kidney function, proteinuria, and hypertension. Renal histopathology showed severe diffuse interstitial nephritis. With oral prednisone and ACE inhibitor therapy, complete recovery of kidney function was not achieved and proteinuria persisted. Therefore, mycophenolate mofetil was initiated. After 8 weeks, serum creatinine decreased, and a nearly complete and sustained resolution of proteinuria was seen, while tapering oral steroid doses. With autoreactive T cells playing a major role in the pathogenesis of both diseases, a common etiology of pancreatitis and interstitial nephritis can be assumed, and the beneficial effects of an inhibitor of lymphocyte proliferation, such as mycophenolate mofetil, can be explained. We infer from our case that mycophenolate mofetil can be effective in the control of simultaneous autoimmune pancreatitis and interstitial nephritis.

CAVHD and CAVH were compared regarding uraemic control in 13 critically ill intensive care patients with acute renal failure (ARF). Patients’ mean age was 60 years. Pretreatment blood urea range was 17–56 mmol/l (33–56 mmol/l in 70% of the patients). All patients received vasopressor drugs, and 92% were on artificial mechanical respiration. From the results of this study both modalities gave adequate uraemic control. There was a notable decrease in the urea and creatinine levels with CAVHD more than with CAVH. There was no statistically significant difference between the two modalities in the urea clearance. However, a significant difference (P<0.05) in creatinine was obtained with CAVHD. Our results suggest that CAVHD is a useful alternative to CAVH in ARF especially when the blood urea level is >30 mmol/l. However, a higher dialysate flow rate (e.g. 25 ml/min) should be used if the urea level is more than 40 mmol/l. CAVH should be reserved for ARF patients in whom fluid overload is a major problem.

A rare case of benign pelvic neurilemmoma with bladder infiltration and ureteral obstruction is presented. This neurally originated tumor may occur anywhere in the body, but involvement of the urinary tract is rare. Management depends upon location and other clinical findings, and in this case, since complete removal was impossible, urinary derivation was employed as a palliative treatment.

Limited data suggest that health literacy (HL) is associated with kidney functions and clinical outcomes in patients with non-dialysis chronic kidney disease (CKD). We aimed to identify factors associated with the level of HL in a CKD population that has not been studied previously. Patients with stage I–V (non-dialysis) CKD according to the Kidney Disease Outcomes Quality Initiative classification were enrolled in the study from two tertiary healthcare centers. Data were collected cross-sectionally using the European Health Literacy Survey (HLS-EU). Data of 208 participants were analyzed. HLS-EU scores had the highest correlations with age (r = − 0.494, p = 0.0001) and education (r = 0.476, p = 0.0001). Estimated glomerular filtration rate (e-GFR) was significantly correlated with HLS-EU score (r = 0.186, p = 0.01). Presence of a self-reported acquaintance with any kind of kidney disease was associated with higher HL. On the other hand, participants with multiple comorbidities, and therefore with more frequent contact with the health system, had lower HL than those without such frequent contact. Similarly, those with a high disease burden had lower HL than those without. HLS-EU scores were also significantly associated with gender, marital status, occupational status, self-perception of health, restriction of daily activities, participation in social activities, place of residence, blood pressure, body mass index, and serum parathyroid hormone and albumin levels. Low HL is prevalent among CKD patients and is associated with e-GFR. Presence of an acquaintance with any kind of kidney disease is positively associated with HL. Presence of multiple comorbidities might be a limiting factor for the improvement of HL, which might also be expected to improve as a result of frequent contact with healthcare providers.

To represent the 15 years’ experience of an academic referral center for the reconstruction of bladder exstrophy–epispadias complex with a modified single-stage approach. Single-staged reconstruction techniques are commonly used for classic bladder exstrophy. However, combined bladder closure and epispadias repair have been taken into great consideration in patients with initially failed reconstruction or delayed primary closure. A total of 49 boys underwent 1-stage bladder and epispadias repair with pubic bone adaptation and without the application of pelvic osteotomy. The mean ± SD age at surgery was 5.23 ± 2.04 months. Continence and social dryness were assessed in the follow-ups with 3 months intervals for the first year and biannually thereafter. The mean ± SD of follow-up was 127.25 ± 71.32 months. Urethrocutaneous fistula, stricture, wound infection, and hemiglans were developed in six distinct patients. However, no other major complications were noted. Three patients (6.1%) remained incontinent; while 32 (65.3%) children were socially continent and 14 (28.6%) children were waiting for toilet training. All the patients without previous failed closure were socially continent, while all incontinent patients had two failed closures in their history. No patient was rendered hypospadiac. Based on the experience of this institution, the application of single-stage reconstructive techniques can lead to continence, cosmetically pleasing appearance with promising outcomes, and reduction of overall operations, hospital stay and costs in the majority of cases as compared to multiple surgical procedures.

The aim of this study was to investigate the role of adhesion molecules in epididymal injury induced by I–R in the rats. A total of 20 male Sprague–Dawley rats were separated into two groups. A sham operation was performed in group 1 (control). In group 2 (I–R), following 6 h of unilateral spermatic cord torsion, 1-h detorsion of the testis was performed. Then, epididymides were removed to measure the tissue levels of malondialdehyde (MDA) and to make histological examination. MDA values increased in the group 2. In the group 2 rats demonstrated significant disorganization of the epithelium and loss of microvilli in the epididymal tissue. No abnormal microscopic findings of the epididymis of the rats in the control group. The tenascin expression in the interstitial area of the epididymis was intense in the group 2. ICAM-1 expression by intense brown staining was seen along the basement membrane in epididymal tissue from I to R group rats. The microvillus sites of the epithelia in I–R group were stained mildly by lectin. The increased expression of adhesion molecules found in epididymal injury induced during postischemic reperfusion might implicate importance of inflammatory infiltration.
