RESUMEN

The requirements of the German statutory accident insurance (DGUV) for the new treatment procedure were presented on 1 January 2013 in a new catalogue. The implementation of the certification of hospitals for the very severe injury procedure (SAV) by the DGUV should have been completed by 2014. These requirements placed high demands on trauma-oriented hospitals because of the high structural and personnel prerequisites. The background to the new organization was the wish of the DGUV for quality improvement in patient treatment in hospitals for patients with very severe occupational and occupation-related trauma by placement in qualified centers with high case numbers. No increase in income was planned for the hospitals to cope with the necessary improvements in quality. After 2 years of experience with the SAV we can confirm for a community hospital that the structural requirements could be improved (e.g. establishment of departments of neurosurgery, plastic surgery and thoracic surgery) but the high requirements for qualification and attendance of physicians on duty are a continuous problem and are also costly. The numbers of severely injured trauma patients have greatly increased, particularly in 2015. The charges for the complex treatment are not adequately reflected in the German diagnosis-related groups system and no extra flat rate funding per case is explicitly planned in the DRG remuneration catalogue. The invoicing of a center surcharge in addition to the DRG charges has not been introduced.

RESUMEN

Due to a safety alert issued by the US Food and Drug Administration (FDA) in 2011 for transvaginal mesh implants to treat female prolapse as a result of numerous reports of complications such as infection, chronic pain, dyspareunia, vaginal erosion, shrinkage and erosion into other organs nearly all industrial products have been withdrawn from the market in the meantime. The United Kingdom, Australia, and New Zealand extended warnings and prohibitions even on the implantation of midurethral slings (TVT, TOT). In view of these current international controversies regarding the use of implanted materials for the treatment of stress incontinence and prolapse and the lack of clear guidelines for the use of biomaterials, the opinion of the Working Group on Urological Functional Diagnostics and Female Urology should provide clarity. The Opinion is based on the SCENIHR Report of the "European Commission's Scientific Committee on Emerging and Newly Identified Health Risks", the "Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence" and in compliance with relevant EAU and national guidelines and the opinion of the Association for Urogynaecology and Plastic Pelvic Floor Reconstruction (AGUB eV). In addition, recommendations are given for the future handling of implants of slings and meshes for the treatment of stress incontinence and prolapse from a urologic viewpoint.

RESUMEN

Open Burch colposuspension has been the gold standard for many years in therapy for stress urinary incontinence and still has a major position in this field by virtue of its excellent long-term results. Tension-free transvaginal tapes nowadays also achieve the same success rates and replace the Burch operation due to less invasiveness of the procedure (1). Burch colposuspension is still used in cases of recurrence and as a combination procedure for stress urinary incontinence and vaginal prolapse. The laparoscopic Burch procedure has been increasingly performed in recent years.Fascial sling procedures are used primarily for recurrence of female stress urinary incontinence and intrinsic sphincter deficiency. The treatment principle is based on repositioning both the urethra when it has descended and the bladder neck as well as increasing the reduced outlet resistance. This approach is still employed today to treat stress urinary incontinence in women.

RESUMEN

Primary malignancies of the seminal vesicles are extremely rare. They must be strictly differentiated from surrounding malignancies that may infiltrate the seminal vesicles from outside (e.g. prostate, rectum, and bladder carcinoma). MEDLINE and CANCERLIT review showed about 50 documented cases of primary seminal vesicle carcinoma so far worldwide in men between 19 and 90 years of age. Early diagnosis may be difficult due to lack of specific symptoms. Especially with a history of voiding dysfunction, haemospermia and/or haematuria, investigators should consider it. Primary diagnostic steps include digital rectal examination, transrectal ultrasound, and transrectal biopsy of the tumour. Additionally, CT and MRT scans show tumour masses corresponding to the seminal vesicles. Adenocarcinoma of seminal vesicles shows no expression of prostate-specific antigen or prostate-specific acid phosphatase, but there may be expression of carcinoembryonic antigen and cancer antigen 125. Radical surgery including radical prostatectomy and/or cystoprostatectomy including pelvic lymph node dissection offers a curative treatment pathway. Adjuvant or inductive medical treatment is of unproven worth, but a combination of hormonal deprivation and radiotherapy seems to be more effective than any chemotherapy.

RESUMEN

Anticholinergic agents are used for treatment of overactive bladder syndrome (OAB) by competitive blockade of acetylcholine at the muscarinic receptor. At present five different subtypes of M-receptors can be differentiated. Primary detrusor effects are mediated by M3-receptors as are side effects like dry mouth and constipation. Cardiac and central nervous system side effects appear to be M2 or M1 related. OAB symptom relief by the unselective drugs tolterodine, oxybutynin or trospium chloride and by M3-selective agents like darifenacin or solifenacin seems to be rather similar. Central side effects are different depending on gastrointestinal reabsorption, serum metabolism and penetration of the blood-brain barrier. Slow release formulations may be better tolerated. Anticholinergics that penetrate the blood-brain barrier may cause cognitive imbalance in older patients, as recent studies have shown for oxybutynin. Here M3-selective agents may offer an advantage.

RESUMEN

Adenocarcinoma of the pancreas has a low 5-year survival rate of approximately 5%. Early diagnostics of pancreatic carcinoma during early tumor stages is made difficult by the lack of symptoms. In particular, individuals suffering from carcinomas located within the pancreatic tail are at high risk of a missed diagnosis. The early symptoms are usually nonspecific (e.g., nonspecific upper abdominal complaints, decrease in weight, loss of appetite, and impaired performance) and are characteristic only in carcinomas of the pancreatic head with painless icterus. If the patient complains of low back pain, a severe infiltration with no chance of a complete surgical resection is found in most cases. An adenocarcinoma of the pancreatic tail was diagnosed in this case report based on a large retroperitoneal extravasation missing further symptoms. The extravasation found represented a primary infiltration of the left ureter which was not diagnosed in primary computed tomography.

RESUMEN

Spontaneous renal rupture is a rare but nevertheless life-threatening complication in cases of benign and malignant space-occupying lesions in the kidneys. A precise preoperative differentiation often turns out to be difficult because of the formation of a hematoma. We report on a 50-year-old female patient with a retroperitoneal hematoma due to a spontaneous renal rupture for which an angiomyolipoma could only by diagnosed after the nephrectomy with histological work-up. In search of the cause, sonography, abdominal computed tomography, and digital subtraction angiography were conducted, which could provide findings suggestive of a space-occupying lesion, but because of the distinct hemorrhagic infarction could not determine whether it was benign or malignant. As shown in this case, when the radiological result is ambiguous, renal exposure is indicated from both a diagnostic and therapeutic standpoint.

RESUMEN

Since the 1980s the management of children and adolescents with meningomyelocele has undergone major changes. The introduction of pharmacotherapy with antimuscarinic agents, clean intermittent catheterization (CIC) and antibacterial prophylaxis has revolutionized the management of children with neurogenic bladder. The co-operation between neonatologists, neurosurgeons, paediatric neurologists, paediatricians, paediatric urologists, paediatric nephrologists, paediatric orthopaedists and paediatric surgeons is necessary to achieve an optimized therapy in each individual patient. In this interdisciplinary consensus paper we provide definitions and classifications as well as a timetable for the appropriate investigations. The conservative and surgical options are explained in detail. A short review is given concerning orthopaedic management, incidence of latex allergy, options for bowel management, diagnosis and treatment of urinary tract infections, problems with sexuality and fertility as well as the long-term compliance of these patients and their relatives.

RESUMEN

Fungal peritonitis (FP) and dialysate leakage have often been reported in association with continuous ambulatory peritoneal dialysis (CAPD), which has to be discontinued in many cases due to these complications. This report describes the first case of dialysate leakage into the urinary bladder of a 70-year-old male patient, after the area of the left ureteral ostium had been very deeply resected. The leakage probably led to severe fungal peritonitis developing 1 day after the ostium resection. The ostium resection was performed in November 2003 after detection of a carcinoma in situ (Cis) in this area and after previous bilateral nephroureterectomies due to multifocal urothelial carcinoma in the kidneys, ureters and bladder. In spite of prior fungal peritonitis and dialysate leakage, CAPD could be successfully initiated 41 days after biochemical manifestation of peritonitis and could be maintained in the patient because of the following reasons: early and effective treatment of FP with fluconazole and voriconazole, spontaneous occlusion of the slitted ostium area, allowance of enough healing time after 2 major abdominal surgeries, during which the patient was placed on extracorporal hemodialysis (which had been started 1 day after nephroureterectomy and ended after the antimycotic treatment) and thorough monitoring of the patient after starting CAPD. In January 2004, the patient could be placed on a cycler peritoneal dialysis and was fully rehabilitated 1 year later.

RESUMEN

INTRODUCTION: Despite recent advances in the field of anticholinergic drugs, lack of efficiency and side effects are still the main reasons for discontinuation of treatment. The introduction of botulinum A toxin was a milestone in the treatment of detrusor overactivity. The treatment, however, is invasive, the duration of the treatment effects is limited, and long-term results are not yet available. The following addresses therapeutic alternatives to local treatment of overactive bladder. MATERIALS AND METHODS: A total of 52 patients received intravesical oxybutynin. In 16 patients, capsaicin was instilled in the bladder and 28 patients were treated with EMDA. RESULTS: Intravesical oxybutynin was successful in 86%; the success rate of capsaicin instillation was 47%. EMDA was successful in 78%. Two transient ischemic attacks following EMDA were observed as significant side effects. CONCLUSION: Besides botulinum A toxin, several effective treatment options are available for patients with detrusor overactivity refractory to oral anticholinergic treatment. Therefore, in each individual patient, possible risks and complications of the different treatment options should be considered thoroughly to find the optimal method in each case.

RESUMEN

Differentiated non-invasive diagnostic procedures allow a discrimination between nocturnal enuresis and behavior-linked urinary incontinence in children with daytime symptoms, which are different entities of a pathological pediatric micturition syndrome. The article describes the diagnostic procedure as well as the therapeutic approach to all forms of micturition disorders in childhood. All behavioral, medical and biofeedback therapeutic methods according to the recently published S2k guidelines from the Association of the Scientific Medical Societies in Germany (AWMF) on enuresis and non-organic (functional) incontinence in children and adolescents are mentioned and discussed.

RESUMEN

BACKGROUND: Our aim was to evaluate the efficacy and tolerability of propiverine hydrochloride (propiverine) in daily practice and to check the risk-benefit relation using previously collected data on 4,390 patients. PATIENTS AND METHODS: A total of 2,932 patients with symptoms of overactive bladder were treated with propiverine over a period of 12 weeks using a multicentre post marketing surveillance. At three visits (inclusion, after 4 weeks, after 12 weeks), parameters from the micturition diary (incontinence episodes, frequency of micturition, micturition volume) were recorded. RESULTS: The number of incontinence episodes during daytime decreased during therapy from 3.6+/-3.8 to 1.2+/-2.3. The number of episodes at night decreased from 1.5+/-2.1 to 0.4+/-0.8 (both P<0.001). The mean volume per micturition improved during therapy (from 142.7 ml to 213.3 ml; +49.5%; P<0.0001). Some 85% of the investigators judged the efficacy of propiverine to be good or very good, 2.1% as not sufficient. The most frequent adverse event was dry mouth (17.3% of the patients after 12 weeks) mostly with low severity. More than 70% of the patients reported good or very good tolerability. Only 0.6% of the patients reported insufficient tolerability.

RESUMEN

The treatment of children and adolescents with meningomyelocele has experienced a clear change in the last 30 years. The establishment of pharmacotherapy, clean intermittent catheterization (CIC) and infection prophylaxis have improved the prognosis for patients and have led to new therapeutic strategies. The interdisciplinary cooperation between neonatologists, neurosurgeons, pediatric neurologists, pediatric urologists, pediatric nephrologists, pediatric orthopedists and pediatric surgeons leads to optimization of individualized therapy. These guidelines present definitions and classifications, investigations and timing which are described in detail. The conservative and operative therapy options for neurogenic bladder function disorders are described and discussed with reference to the current literature. The brief overview provides in each case assistance for the treating physician in the care of this patient group and facilitates the interdisciplinary cooperation.

RESUMEN

BACKGROUND: In prostate centers of the Governing Body of German Prostate Centers (DVPZ, Dachverband der Prostatazentren Deutschlands e.V.) treatment data from 3 university clinics, 21 treatment clinics, 3 private clinics and 330 general practitioners incorporated under 22 certificates are collated, in order to document the quality and type of cross-sectoral and interdisciplinary treatment, in particular of prostate cancer (PCA) patients. METHODS: This analysis is based on the DVPZ UroCloud data sets from 20 July 2015. The UroCloud reflects the web-based chronological disease development and quality parameters. For the descriptive analysis of particular key figures, available complete data sets were selected. RESULTS: Of the centers 22 held a valid certificate and fulfilled all required case numbers and structural prerequisites at the primary certification or recertification. In three cases a reauditing led to requirements before certification. Since 2005 a total of 9650 PCA patients have been pseudonymized and followed up (41,247 follow-up forms, 4.3 forms per patient). In 2014 the median number of newly documented PCA patients was 61 per center (minimum 7 and maximum 295). Radical prostatectomy (RP) dominated with 4491 (56 %) cases followed by primary hormonal therapy (1210 cases, 15 %), irradiation (809, 10 %) and non-interventional therapy, such as active surveillance (AS) or watchful waiting (WW) in 760 cases (10 %). A prostate-specific antigen (PSA) reduction was documented in 50 % of the patients with a preoperative PSA value > 20, in 60 % of pT4 tumors and in 50 % of patients with a tumor Gleason score of 9-10. A positive incision margin (R+) was found in in 15 % of pT2 stages, 41 % of pT3 stages and 85 % of pT4 stages. A secondary intervention was documented in 6.5 % of RP. CONCLUSION: The DVPZ certificate reflects the complete spectrum of treatment of PCA patients. The strength of the certificate lies in the documentation of patient development and a simultaneous collation of quality parameters.

RESUMEN

OBJECTIVES: Antegrade colonic enemas for neurogenic fecal incontinence via reverse reimplanted appendices (Mitrofanoff principle) have been primarily reported by Malone and coworkers in 1990. We used a modification of the described surgical technique and treated the first 10 patients with neurogenic fecal incontinence due to spina bifida. The surgical procedure and the results are reported. METHODS: Since November 1991, we have used a surgical procedure similar to the appendiceal continence mechanism in urinary diversion to establish a continent colonic cutaneous stoma for antegrade enemas in 10 myelodysplastic patients (4 females, 6 males; median age 13.2 years [range 6 to 26]) with severe neurogenic fecal incontinence. The average follow-up is now 26.4 months (range 12.5 to 50). All patients had neurogenic bladder dysfunction successfully managed by clean intermittent catheterization, anticholinergic drugs, or artificial sphincter implantation. The surgical technique for fecal incontinence included the partial orthotopic submucosal imbedding of the appendix into a cecal tenia and the fixation of the ileocecal region at the inner side of the abdominal wall after creation of an appendicocutaneous catheterizable stoma. RESULTS: All patients reached fecal continence for at least 38 hours (median 45.3) by using antegrade colonic enemas with 1.5% saline solution (n = 9) or GoLYTELY solution (n = 1), 0.5 to 1.5 L every 2 to 3 days. All other therapies (diet, oral medication, rectal purgative, or enema) to reach fecal continence had previously failed. There were only two complications seen at the follow-up. One boy with an artificial urinary sphincter presented with infection of the sphincter system, which led to explantation. Another boy presented 15 months after creation of the colonic appendiceal stoma with saline intoxication possibly due to a homemade saline solution. CONCLUSIONS: We conclude that the antegrade colonic enema via an orthotopic continent appendiceal stoma is a safe and highly effective treatment modality for fecal incontinence in patients with neurogenic bowel dysfunction if nonsurgical management has failed.

RESUMEN

The radioligand binding properties of [3H]prazosin and [3H]tamsulosin at alpha1-adrenoceptors of several rat tissues, human prostate and cloned rat and human alpha1-adrenoceptor subtypes were compared in Tris/EDTA buffer unless otherwise indicated. The affinity of [3H]tamsulosin at tissue and cloned alpha1A- and alpha1B-adrenoceptors was somewhat greater and smaller, respectively, than that of [3H]prazosin. In most rat tissues and at cloned rat alpha1A- and alpha1B-adrenoceptors, [3H]tamsulosin had a smaller Bmax than [3H]prazosin. Studies with rat liver showed that this was due to considerably poorer labeling of agonist low affinity sites, while both radioligands detected similar numbers of agonist high affinity sites. Statistically significant differences in the number of binding sites for both ligands were not detected in HEPES or glycylglycine buffer, as the detectable receptor number for [3H]prazosin and [3H]tamsulosin tended to be smaller and greater, respectively, in these than in Tris/EDTA buffer. Among human alpha1-adrenoceptor subtypes [3H]tamsulosin labeled fewer sites than [3H]prazosin for alpha1B- but more sites for alpha1A- and alpha1D-adrenoceptors. We conclude that [3H]prazosin and [3H]tamsulosin do not detect the same number of alpha1-adrenoceptors under a variety of conditions. This should be taken into account in the interpretation of data obtained with either radioligand.

RESUMEN

In order to characterize inverse agonism at alpha1B-adrenoceptors, we have compared the concentration-response relationships of several quinazoline and non-quinazoline alpha1-adrenoceptor antagonists at cloned hamster wild-type (WT) alpha1B-adrenoceptors and a constitutively active mutant (CAM) thereof upon stable expression in Rat-1 fibroblasts. Receptor activation or inhibition thereof was assessed as [3H]inositol phosphate (IP) accumulation. Quinazoline (alfuzosin, doxazosin, prazosin, terazosin) and non-quinazoline alpha1-adrenoceptor antagonists (BE 2254, SB 216,469, tamsulosin) concentration-dependently inhibited phenylephrine-stimulated IP formation at both WT and CAM with Ki values similar to those previously found in radioligand binding studies. At CAM in the absence of phenylephrine, the quinazolines produced concentration-dependent inhibition of basal IP formation; the maximum inhibition was approximately 55%, and the corresponding EC50 values were slightly smaller than the Ki values. In contrast, BE 2254 produced much less inhibition of basal IP formation, SB 216,469 was close to being a neutral antagonist, and tamsulosin even weakly stimulated IP formation. The inhibitory effects of the quinazolines and BE 2254 as well as the stimulatory effect of tamsulosin were equally blocked by SB 216,469 at CAM. At WT in the absence of phenylephrine, tamsulosin did not cause significant stimulation and none of the other compounds caused significant inhibition of basal IP formation. We conclude that alpha1-adrenoceptor antagonsits with a quinazoline structure exhibit greater efficacy as inverse agonists than those without.

RESUMEN

The coupling of human alpha1-adrenoceptor subtypes to protein kinase C (PKC) and PKC-related signalling events were investigated in rat-1 fibroblasts stably expressing alpha1A-, alpha1B- or alpha1D-adrenoceptors at densities of 1328+/-200, 5030+/-703 and 150+/-14 fmol/mg protein respectively. In functional assays the alpha1-adrenoceptor agonist phenylephrine significantly stimulated PKC (assessed as increased activity in the membrane fraction) in cells expressing alpha1A- or alpha1B- but not alpha1D-adrenoceptors. In immunoblot assays phorbol ester treatment enhanced membrane-associated immunoreactivity of PKCalpha, PKCdelta and PKCepsilon to a similar extent in all three cell lines. Stimulation of alpha1A- and alpha1B-adrenoceptors also increased immunoreactivity of PKCalpha, PKCdelta and PKCepsilon in the membrane fraction, while alpha1D-adrenoceptor stimulation yielded only very small and inconsistent alterations. Immunoreactivity of PKCzeta was not consistently affected by phorbol ester or phenylephrine in any of the cell lines. Stimulation of all three alpha1-adrenoceptors time- and concentration-dependently increased inositol phosphate formation. Maximum activation occurred with the order alpha1A approximately = alpha1B > alpha1D. Phenylephrine also concentration dependently elevated free intracellular [Ca2+] in all three cell lines with the order of efficacy alpha1A > alpha1B > alpha1D. In the presence of ethanol, phenylephrine stimulated phosphatidylethanol formation in alpha1A- and alpha1B-adrenoceptor-expressing cells time and concentration dependently but only weakly and inconsistently in alpha1D-adrenoceptor-expressing cells. The efficacy of phenylephrine (100 microM) relative to that of noradrenaline (100 microM) for stimulation of phosphatidylethanol formation was similar (> or = 75%) for all three subtypes. The alkylating agent phenoxybenzamine concentration dependently reduced alpha1A-adrenoceptor density and phenylephrine-stimulated Ca2+ elevations to levels seen with alpha1D-adrenoceptors but reductions of phenylephrine-stimulated phosphatidylethanol formation were weaker. We conclude that human alpha1A- and alpha1B-adrenoceptors expressed in rat-1 cells couple to activation of PKCalpha, PKCdelta and PKCepsilon but not PKCzeta; this may involve stimulation of phospholipases C and D and intracellular Ca2+ elevations. Activation of these pathways by alpha1D-adrenoceptors appears to be much weaker and was not detected consistently; this was not fully explained by weak partial agonism of phenylephrine at this subtype or by lower receptor densities. Overall the alpha1A-adrenoceptor may have the highest efficiency of stimulus-response coupling among human alpha1-adrenoceptor subtypes.

RESUMEN

We have tested the hypothesis that smaller alpha1B-adrenoceptor labeling by [3H]tamsulosin compared to [3H]prazosin is related to differential recognition of agonist low affinity states. Paired saturation binding experiments with [3H]prazosin and [3H]tamsulosin were performed in membrane preparations from rat liver and Rat- fibroblasts stably transfected with wild-type hamster alpha1B-adrenoceptors or a constitutively active mutant thereof. In all three settings [3H]tamsulosin labeled significantly fewer alpha1B-adrenoceptors than [3H]prazosin. In noradrenaline competition binding experiments, the percentage of agonist low affinity sites was smallest for the constitutively active alpha1B-adrenoceptor but the percentage of agonist low affinity sites recognized by [3H]tamsulosin and [3H]prazosin did not differ significantly. We conclude that [3H]tamsulosin labels fewer alpha1B-adrenoceptors than [3H]prazosin but this is not fully explained by a poorer labeling of agonist low affinity sites.

RESUMEN

The therapy of mixed urinary incontinence is still discussed controversially. Surgical procedures were seen as a minor opinion in these cases, because the urge-symptoms remain stable or even become worse after incontinence-surgery. We here present a prospective-randomized double-blinded multi-center trial with Tolterodine extended-release 4 mg once daily in 410 female patients with mixed incontinence treated in Germany. After 8 weeks of treatment we saw a nearly 60% significant regression of the symptoms of mixed incontinence. Therefore the anticholinergic treatment with tolterodine extended-release of women is a successful treatment option in mixed incontinence.
