It is important that any patient with a urinary diversion can accept the psychological impact alongside the surgical and physical aspects. However, there are currently no validated methods or instruments available to allow direct measurement of this phenomenon in these patients. Health-related quality of life (HRQoL) is often high following different types of urinary diversion-this may suggest a high acceptance level and thus may act as a secondary end point. Such an assessment is a retrospective validation of successful patient selection, allowing us to redirect the nihilistic misinterpretation that urologists should return to offering ileal conduits as a standard. In modern urinary diversion, high patient acceptance develops from comprehensive counselling providing a realistic expectation, careful patient-to-method-matching, strict adherence to surgical detail during the procedure and a meticulous lifelong follow-up. Coping strategies, disease-related social support and confidence in the success of treatment are among other factors which contribute to acceptance of urinary reconstruction as either independent or combined factors. Significant experience is required in every respect, as misjudgement and mistakes in any of these issues may be detrimental to the patients' health. It should be acknowledged that there is no 'best' urinary diversion in general terms. A reconstructive surgeon must have all techniques available and choices need to be tailored to the individual patient.

The antiphospholipid antibody syndrome (APLS) is characterised by the presence of antiphospholipid antibodies in association with thrombotic disorders of the arterial and/or venous system, spontaneous abortion and thrombocytopenia. Several studies have shown that end-stage renal disease patients with APLS are at extremely high risk for graft thrombosis and graft loss after kidney transplantation.We report on the treatment and clinical courses of 6 APLS renal transplant patients.Of 3 patients treated with low-dose subcutaneous heparin two had early graft loss due to venous graft thrombosis; of those patients treated by systemic heparin (PTT goal 45-55 s) and followed by coumadin (INR 2.5-3.0) only one had early graft loss whereas 2 grafts are doing well 2 years post-transplant.Our experience as well as recently published data suggest that kidney transplantation can be performed successfully in APLS patients if anticoagulation therapy is performed consistently. A general APL antibody screening prior to kidney transplantation does not seem to be justified at present. A prospective, randomised multicenter study is warranted to evaluate the management of these patients with respect to intensity, type and duration of anticoagulation therapy.

Nocturnal enuresis (bedwetting) is one of the most frequent urological symptoms in children, affecting about 20% of five year olds. It is a heterogeneous disorder with a whole variety of etiologic factors (genetic, endocrinological, neurobiological), particularly a dysfunction of the lower urinary tract. Despite the prevalence of enuresis many questions regarding the complex pathophysiological mechanisms remain unanswered. While nocturnal enuresis per se is clearly not a disease, psychosocial problems have been reported in up to 40% of affected children. Management strategies comprise behavioural and pharmacological approaches, either in isolation or combined. Although expectations were high, especially with pharmacological interventions, the results are usually disappointing with high recurrence rates. Extensive analyses of the available literature on the efficacy of enuresis treatment modalities reveal a poor quality of many trials with a whole range of methodological flaws. Therefore, further comparative studies of adequate methodological quality are needed.

The assumption that enterocystoplasty in children has a detrimental effect on linear growth has been based almost exclusively upon a chance finding in a retrospective study 10 years ago. We re-evaluated the same research question in a larger cohort and with a longer follow-up.Between 1982 and 1997, 242 children and adolescents underwent enterocystoplasty. Patients with conditions involving organ systems apart from the urinary tract, and those with myelomeningocele, malignant diseases, reduced glomerular filtration rate and incomplete notes were excluded. In the definitive study cohort (123; mean age at operation 8.6 years; mean age at investigation 16.8 years), enterocystoplasty had been undertaken using colon in 70, ileum in 37, a combination of both in 11, ileocaecal segments in three and stomach in two patients.In all, 1215 height and weight measurements had been recorded. The distribution of percentile positions before and after enterocystoplasty showed a normal configuration, with 83 % and 80 % of patients growing within two standard deviations of the 50th percentile. After surgery, 85 % either remained the same or reached a higher percentile. Nineteen (15.5 %) were in a lower position, with a similar tendency in the weight percentile. A clinically relevant growth disorder was recognized in four patients with a complete endocrinological evaluation; in none of these was enterocystoplasty thought to be a causal factor.It is very unlikely that loss of the preoperative percentile position on the growth curve in 15 % of children after enterocystoplasty is a consequence of that particular surgery. Rather, it is a non-specific phenomenon that has to be considered in any clinical population of the same size and age distribution after the same length of time.

We report on the case of a 31-year-old male patient with focal testicular vasculitis as the only clinical manifestation of endangiitis obliterans (Winiwarter-Buerger disease), who presented with acute scrotal pain and swelling suggestive of a testicular tumor. Doppler sonography revealed significantly increased vascularization at the borders of the lesion, which rather indicated a vascular process; however, the presence of solid areas meant that the possibility of testicular cancer could not be excluded. Left inguinal orchiectomy was performed. The surgical specimen revealed histological patterns compatible with endangiitis obliterans; Raynaud phenomenon was the only sign of systemic disease, and no other organs were found to be affected. Despite the high sensitivity and specificity of ultrasound/Doppler sonography, in the differential diagnosis of an unexplained testicular mass surgical exploration is still mandatory. The different types of focal vasculitis are described and discussed with reference to the literature.

61 Patients with histologically proved primary mediastinal tumour were examined by computed tomography (CT) of the thorax prior to surgery. The retrospective analysis of the CT scans led to the correct diagnosis in 77% of cases. CT-values (HE), calcifications or form of tumour growth was found to be unreliable in the classification of tumour status.
