[Urinary tract infections in infants and children -- a consensus on diagnostic, therapy and prophylaxis].

Urinary tract infections (UTI) are among the most common bacterial infections in infants and children. The early diagnosis of a pyelonephritis and its rapid, calculated antibacterial therapy are decisive for the prognosis. Urogenital anomalies, renal damage and bladder dysfunction may influence the risk of recurrences of UTI and pyelonephritic scarring. Diagnostic strategies therefore should focus on their early recognition. Pediatricians, urologists and infectiologists are cooperating in diagnostic, therapy and prophylaxis of UTI. The aim of the interdisciplinary consensus presented was to work out a concept which may help to manage childhood UTI in daily practice.

[Modern concepts in the treatment of intersexuality].

Treatment of intersexuality is demanding and requires experience and interdisciplinary cooperation. Preconditions for normal development and clear gender identification are correct (not emergency) diagnosis and gender assignment and adequate hormonal and surgical treatment. Surgery should be done early (6th to 15th month) as atraumatically as possible with cosmetically and functionally satisfying results. These preconditions are not met consistently, resulting in a 20-25% rate of mistakes in diagnosis and treatment. In experienced centers, feminizing genitoplasty, even of the severest forms, is carried out through a perineal one-stage approach. Masculinization corresponds to surgery for severe hypospadias. The high risk of malignant degeneration requires removal of all inadequate structures such as streak gonads, uterus, and tubes. In 5-alpha deficiency, early gonadectomy and feminization are not recommended since gyneophile behavior can be expected. Late or non-correction is rejected by the majority of psychiatrists. Many problems remain unclear and controversial due to lack of knowledge. In the future they can only be solved through cooperation, documentation, and observation of these individuals over their lifetime.

[European Association of Urology guidelines on urinary and male genital tract infections].

Today, the classical bacteria that cause venereal diseases, e.g. gonorrhea, syphilis, chancroid and inguinal granuloma, only account for a small proportion of all known sexually transmitted diseases (STDs). Other bacteria and viruses as well as yeasts, protozoa and epizoa must also be regarded as causative organisms of STD. Taken together, all sexually transmitted infections comprise more than 30 relevant STD pathogens. However, not all pathogens that can be sexually transmitted manifest diseases in the genitals and not all infections of the genitals are exclusively sexually transmitted. Concise information and tables summarising the diagnostic and therapeutic management of STDs in the field of urology allow a synoptic overview, and are in agreement with the recent international guidelines of other specialist areas. Special considerations (i.e. HIV infection, pregnancy, infants, allergy) and recommended regimens are presented.

Penile ossification and acquired penile deviation.

We report on 3 patients with penile deviation during erection caused by ossification in the corpora cavernosa. In each case hard plaques could be palpated. These indurations were removed through a dorsal longitudinal incision. Histologically, solid bone was demonstrable. Two patients were able to resume normal sexual intercourse, but one became impotent following postoperative cavernitis. Penile ossification is rare in man, and its etiology is unknown. It bears no relationship to the os penis normally present in many other mammals. Diagnosis is best made by palpation and X-ray examination. The treatment of choice for symptomatic ossification is surgical excision.

Nitrofurantoin versus trimethoprim for low-dose long-term prophylaxis in patients with recurrent urinary tract infections. A prospective randomized study.

In a prospective randomized study 38 patients with recurrent urinary tract infections (rUTI) were included to take either 50 mg Nitrofurantoin (n = 19) or 50 mg Trimethoprim (n = 19) as low-dose long-term prophylaxis for half a year. Compliance was checked weekly by Bacillus subtilis spore test strips sent in by mail. The infection rate was reduced from more than three per patient year to 0.01. There were no significant differences between the two groups concerning the recurrence rate (Nitrofurantoin: one rUTI; Trimethoprim: three rUTI) or side effects. Under Nitrofurantoin treatment 3 symptomatic fungal infections occurred. Trimethoprim and Nitrofurantoin are equally suitable for low-dose long-term prophylaxis in rUTI. Surveillance of compliance gives important hints for failure of prophylaxis.

[Treatment of hypospadias].

Treatment of all forms of hypospadias is difficult. Several abnormal components have to be differentiated and corrected in a very tight space, in addition to which the blood supply must be preserved and infection prevented. Technical progress now allows early correction (around the age of 12 months) in a single procedure, using methods that date back to the last century. Cosmetic results are as important as functional ones. The glans should be reconstructed around the neomeatus, and the penile shaft should be straight. Microsurgical techniques, short transurethral urinary diversion and reliable dressings are important. Strategies, the sequences of surgical procedures and a selection of practical methods are presented and discussed.

[Diagnosis and therapy of xanthogranulomatous pyelonephritis].

Xanthogranulomatous pyelonephritis (XGP) is a rare, unilateral and multifocal inflammatory response of the kidney against bacterial toxins. In the Department of Urology of the University of Freiburg 6 patients with XGP were observed within 10 years. Despite modern diagnostic procedures differential diagnosis from kidney tumors and other parenchymal kidney diseases remains difficult. Recurrent urinary tract infections, fever, urolithiasis, obstruction and leucocytosis may be indicative of XGP. The diagnosis has to be confirmed by surgical intervention which preferably should preserve functioning renal tissue. The prognosis in general is quite good.

[MR of the urinary tract in pregnancy].

A report on the application of standard 2D-FT MR combined with RARE-MR-Urography in a pregnant woman with right sided abdominal pain, dilated upper urinary tract and possible stone or inflammatory disease. This technique visualised the complete obstructed ureter in relation to the surrounding organs (uterus, vessels), allows precise diagnosis of the cause of the obstruction and avoids ionising radiation.

Development of nosocomial and iatrogenic urinary tract infections (UTI) following urological interventions. A prospective clinical study.

Development of nosocomial and iatrogenic UTI was investigated over 3 months period of time. Included were 140 patients following 228 instrumentations or endoscopical or surgical interventions. Of these 84 were carried out under antimicrobial medication. 30 UTIs developed 1-8 days after the various procedures (= 13.2%): 10% after TUR-B, 14% after TUR-P and ureteral instrumentation, 16% following cystoscopy and catheterisation. No significant difference was observed between: Males and females, patients with or without antimicrobial medication, younger and older patients and after long or short procedures. Indwelling catheters remain sterile for 3 days. Though antimicrobial prophylaxis did not significantly influence the generally low rate of infection it appeared as a trend that the elderly patient who requires repeated interventions and who suffers from additional diseases as diabetes, consuming tumours and renal insufficiency may benefit from medication.

Clinical evaluation of Timentin in complicated urinary tract infections.

Timentin proved to be highly effective in the treatment of 70 urological patients suffering from complicated urinary tract infections. There were few adverse effects, and development of resistance was not observed. Surgical treatment was possible in each case, without any septic complications. The results show that Timentin is a very useful drug for the urologist who often treats complicated urinary tract infections, especially because of its low re- and super-infection rate and the absence of development of resistance.

[Diagnosis and therapy of ectopic ureters and ectopic ureteroceles with double kidneys].

Diagnosis and treatment of ectopic ureters and ectopic ureteroceles with renal duplication is a rewarding challenge for any urologist, requiring specific knowledge, awareness of the anomaly and good surgical technique. The diagnosis is primarily based on the correct interpretion of the medical history and the excretory urogram, irreplaceable by sonography. Confusing details can easily be interpreted when the anomaly is detected, or the patient will be left on a long and frustrating path of medical treatment, diagnostic interventions, possibly leading to psychotherapy. The classical triad: renal duplication, incontinence and normal micturition is rarely helpful in complicated cases, compared to the typical findings on the excretory urogram which sometimes are incomplete or only suggestive but still have the highest diagnostic value. Their recognition usually leads to correct diagnosis and treatment. Modern surgical and anesthesiological techniques allow a one stage approach to correct the anomaly and avoid further complications. However, if the risk is considered to be too high, a two stage approach is justified starting with a heminephrectomy. After this 20% will require further surgical treatment of the bladder, due to complications. Dysplastic and nonvisualizing renal segments should not be preserved nor should dilated, ectopically ending ureters. Minimal surgical interventions, reducing, but not solving the problem (incision of ureteroceles, interpelvic anastomosis) are not recommended in modern urological treatment.
