RESUMO
PURPOSE: To evaluate stool habits and associated quality of life (QoL) in a matched pair analysis of patients who underwent continent cutaneous diversion using the ileocecal segment [Mainz pouch I (MzPI)] with an intussuscepted ileal nipple as efferent segment with those receiving an ileal conduit (IC) after radical cystectomy. METHODS: We identified 250 patients who underwent radical cystectomy and urinary diversion (UD) with either MzPI with an ileal nipple or IC in our database. A detailed history of stool habits using the modified Wexner score was obtained, and questions addressing general lifestyle, comparison of symptom differences before and after surgery considering bowel function as well as bowel-associated QoL were assessed. RESULTS: Forty-five age- and sex-matched pairs could be compared. Overall, stool incontinence (p = 0.481) and the Wexner score (p = 0.464) revealed no differences between both groups. However, patients with MzPI as compared to those with IC had significant higher rates of stool frequency (53 vs 31 %), softer stool consistencies (60 vs 13 %), diarrhea (62 vs 20 %) and a lower rate of constipation (4 vs 22 %). Patients with MzPI had a trend toward lower bowel-associated QoL compared with patients with IC. Similarly, the MzPI group reported a significantly impaired overall postoperative QoL (51 %) compared to the IC group (29 %) (p = 0.024). CONCLUSIONS: Patients following UD by MzPI have an increased stool frequency and softer stool consistency. However, there is no difference between both groups in terms of de novo stool incontinence. Change in bowel habits should be part of preoperative informed consent in any kind of UD. Careful patient selection is of paramount importance.

PURPOSE: Pubic symphysitis (PS) after urological operations is uncommon. This is a systematic single-institution review of patients with transurethral resection of the prostate (TUR-P) with the aim to determine the incidence of PS after TUR-P and to identify a risk profile. MATERIALS AND METHODS: In the past 15 years, 12,118 transurethral operations were performed in our department, 33.4% (n = 4045) were TUR-P, and 84.6% (n = 3421) had routine suprapubic trocar placement. A systematic retrospective analysis identified 12 patients, who developed PS (0.297%). RESULTS: Median age was 69.5 years (64-83). All patients had voiding difficulties. Urine culture had been positive in three cases. All 12 TUR-Ps were monopolar resections, and n = 11 patients had a suprapubic trocar. Median resection weight was 47.5 g (10-100). Two patients had a perforation of the capsule. Histopathological examination revealed chronic prostatitis in nine cases. After 1.0 ± 1.2 months, all patients developed pain in the pubic region. All patients underwent MRI, which suggested PS. Symptomatic and antibiotic medications were administered. Final outcome was resolution of symptoms in all patients after 3.8 ± 5.6 months. No patient retained voiding difficulties. CONCLUSION: PS remains a rare complication after TUR-P. We could not identify a single cause for developing PS. In our study, suprapubic trocar placement (11/12), chronic prostatic inflammation (9/12), previous UTI (3/12) and extended resection (2/12) were overrepresented. Inflammatory, thermic and/or surgical damage of the capsule may be causative. Patients require antibiotic and symptomatic medication. However, prognosis for remission is excellent.

INTRODUCTION: Rhabdomyosarcoma (RMS) accounts for 5% of all pediatric tumors; 15-20% of these tumors are located in the urogenital tract, mostly originating from the prostate or bladder. In the light of the steadily improving prognosis for patients with RMS through interdisciplinary-multimodal study protocols with 60-70% long-term survivors, non oncological aspects such as erectile function (EF) have become increasingly important. The aim of this study was to evaluate EF in patients having undergone treatment for RMS of the bladder and prostate. DESIGN: The medical records of 24 male patients having undergone surgical treatment for pelvic RMS between 1975 and 2014 were reviewed, and follow-up was obtained. Erectile function was determined using the Self-Estimation Index of Erectile Function-No Sexual Intercourse (SIEF-NS) and the Erection Hardness Scale (EHS). Potential prognostic factors were evaluated in respect to their impact on EF. RESULTS: Thirteen patients were included in the study (median age 20 years). Median follow-up period was 12.7 years (1.09-39.85). All patients completed the EHS; nine patients completed the SIEF-NS. All three patients with preserved erectile function (EHS = 4) showed a score indicating no or minimal impairment on sexual function on SIEF-NS (median 33). None of these patients had undergone external radiotherapy, and radical cystoprostatectomy had been performed before the third year of life in two out of three. The remaining patients had erectile dysfunction (EHS = 0). Three patients had an unsatisfying treatment attempt with sildenafil. Seven patients, including all with failures of oral PDE-5-inhibitors, were successfully treated with intracavernous injection of Alprostadil (Summary Table). DISCUSSION: This was the largest study, to date, evaluating erectile EF in patients treated for RMS of the bladder or prostate. EF was preserved in some patients, despite aggressive treatment modalities. Patients affected by erectile dysfunction after therapy showed limited response to PDE-5 inhibitors, but even after failure of the latter, an intracavernous injection of Alprostadil showed a significant improvement in EHS and SIEF-NS. Limitations of the study included the retrospective nature, small sample size, and heterogeneity of underlying disease, stage, and treatment modalities used. CONCLUSIONS: The results suggested that in a subset of patients, EF was preserved after radical surgical treatment of RMS, especially in young boys. Intracavernous injection of Alprostadil was effective, even after failure of PDE-5-inhibitors, and should be offered to patients without spontaneous erections, whereas PDE-5-inhibitors appeared to be largely ineffective. External radiation therapy appeared to have a negative impact on EF.

The never ending discussion about the diagnostics and treatment of vesicoureteral reflux (VUR) now includes arguments for diagnostic nihilism as well as invasive diagnostics and therapy, which is reminiscent of the debate on prostate cancer in adulthood. The common goal of all currently competing diagnostic strategies and approaches is the prevention of renal scars by the most effective and least burdensome approach. There is a difference between acquired pyelonephritic scars with VUR (acquired reflux nephropathy) and congenital reflux nephropathy (primary dysplasia) which cannot be influenced by any therapy.The VUR can be verified by conventional radiological voiding cystourethrography (VCUG), by urosonography, radionuclide cystography or even by magnetic resonance imaging (MRI). The guidelines of the European Association of Urology/European Society for Paediatric Urology (EAU/ESPU) recommend radiological screening for VUR after the first febrile urinary tract infection. Significant risk factors in patients with VUR are recurrent urinary tract infections (UTI) and parenchymal scarring and the patients should undergo patient and risk-adapted therapy. Infants with dilating reflux have a higher risk of renal scarring than those without dilatation of the renal pelvis. Bladder dysfunction or dysfunctional elimination syndrome represents a well-known but previously neglected risk factor in combination with VUR and should be treated prior to any surgical intervention as far as is possible.Certainly not every patient with VUR needs therapy. The current treatment strategies take into account age and gender, the presence of dysplastic or pyelonephritic renal scars, the clinical symptoms, bladder dysfunction and frequency and severity of recurrent UTI as criteria for the therapy decision. The use of an antibacterial prophylaxis as well as the duration is controversially discussed. Endoscopic therapy can be a good alternative to antibacterial prophylaxis or a surveillance strategy in patients with low grade VUR. In patients with dilating VUR and given indications for surgery, endoscopic treatment can be offered. However, parents should be completely informed about the significantly lower success rate of endoscopic therapy compared to open surgical procedures. The open surgical techniques guarantee the highest success rates and should be used in patients with a dilating VUR and high risk of renal damage.

Therapy of vesicoureteral reflux (VUR) has steadily changed during the last decade. Open surgical procedures, e.g. extravesical reflux repair with the Lich-Gregoir technique or ureterocystoneostomy with the psoas hitch technique, reference standards with excellent success rates, are less frequently used. Since its approval by the US Food and Drug Administration (FDA) endoscopic reflux therapy with Deflux® has gained more and more popularity. However, the usage of so-called bulking agents, e.g. Deflux®, still remains controversial in dilating reflux, while its application for low-grade VUR is increasingly being accepted. Despite higher recurrence rates in all grades of VUR, the use of the "minimally invasive injection" is increasing. The question has to be answered which therapy - if necessary - benefits the patient most. Which role has the subureteral injection gained and are open surgical procedures for VUR therapy "out"?

Metabolic long-term complications and consequences after urinary diversion are somewhat neglected. Subclinical metabolic disturbances are quite common; however, complications are rare. The absorptive surface of the bowel segment is lost for the physiological function of the gastrointestinal tract. Some studies demonstrated that at least some of the absorbent and secreting properties of the bowel are preserved if exposed to urine. For each bowel segment typical complications are reported. Using ileal and/or colon segments, hyperchloremic metabolic acidosis may occur. Studies demonstrated that metabolic effects are not as severe as suspected and could be prevented if a prophylactic treatment is started early.The resection of ileal segments is responsible for malabsorption of vitamin B(12) and bile acid; when using colonic segments, electrolyte disturbances are more common. Careful patient selection, meticulous follow-up and prophylactic treatment are crucial to prevent metabolic complications.
