ABSTRACT

With increasing life expectancy there is also an increased need for the management of older (≥ 80 years) patients with the diagnosis of muscle-invasive bladder cancer. Radical cystectomy with urinary diversion is the state of the art treatment (with neoadjuvant chemotherapy, as long as the patient is fit enough). Choosing the best urinary diversion with respect to morbidity compared to functionality and quality of life remains a challenge in these patients. Physical age alone is not decisive for making a decision. A thorough preoperative assessment of medical features, physical and cognitive impairments is more important. Older patients are generally provided with an ileal conduit as an incontinent urinary diversion, as the intervention involves reduced operating times and complexity compared to continent urinary diversions; however, in the case of good health status with an adequate life expectancy and sufficient compliance, continent diversions may be considered even in aged candidates. In the case of multimorbid patients with a high perioperative risk, ureterostomy with permanent ureteric stents is an important alternative. Most importantly, a thorough preoperative counselling enables patients to reach an informed decision.

ABSTRACT

The reprocessing of medical products is an important topic both in urological practices and in hospitals. The complexity is caused by the increasing variety of medical instruments and also by the increasing demands on the legally required quality of the reprocessing. The Robert Koch Institute (RKI) and the Federal Institute for Drugs and Medical Devices (BfArM) have published recommendations for the processing of MD and last updated them in 2012. This article summarizes the legal framework for the reprocessing of medical devices, how medical devices are categorized before the appropriate procedure for reprocessing can be selected and the various steps in the reprocessing. A special focus is placed on medical products that are typically found in urological practices or outpatient departments and are processed there. Furthermore, the necessity of validating the processing method and the required training (expertise) of the personnel are discussed.

ABSTRACT

BACKGROUND: En bloc tumor resection of bladder tumors (ERBT) is a novel alternative procedure to conventional resection of bladder tumor (cTURBT), which might help to address common problems of the standard method, such as inadequate detrusor muscle in specimens, high re-resection rates and high recurrence rates. OBJECTIVE: To analyze current data on ERBT in efficacy and safety compared to cTURBT. DATA SOURCES: PubMed. STUDY SELECTION: Two independent authors identified trials based on keywords and inclusion criteria. A third author was consulted in case of discrepancies. Screening keywords: ERBT, en bloc transurethral resection of bladder tumor, TURBT en bloc. A meta-analysis of 13 studies was performed. The effect size was estimated based on odds ratios and mean differences including their corresponding two-sided 95% confidence intervals. DATA SYNTHESIS: The analyzed studies comprised a homogenous collective in terms of tumor size, tumor multiplicity and tumor stage. Operation time did not significantly differ between the methods. Differences were observed in hospitalization and catheterization time in favor of ERBT. Reported complications did not show clear differences. There was significantly more detrusor muscle in the specimens in the ERBT group. No significant differences were found in recurrence up to 2 years of follow-up. CONCLUSION: ERBT is a safe alternative to conventional TURBT with promising features regarding effective resection of detrusor muscle. More standardized data on recurrence rates, different resection modalities and resection margin results are needed.

ABSTRACT

Transurethral resection of bladder tumors (TURBT) is the standard of care for the diagnostics and primary treatment of bladder tumors. These are removed by fragmentation using loop diathermy. The resection area is coagulated for hemostasis. An important aspect is always a complete resection with an adequate amount of detrusor muscle in the specimen. Postoperative intravesical instillation of single-shot chemotherapy has been proven to reduce recurrence rates. Methods for improved tumor visualization (particularly photodynamic diagnostics) are used to enhance tumor detection rates particularly in multifocal tumors or carcinoma in situ (CIS). Thus, recurrence and progression rates can be reduced. Depending on the histological examination of the TURBT specimen, follow-up treatment for non-muscle invasive bladder tumors are adjuvant instillation treatment using chemotherapy or Bacillus Calmette-Guérin (BCG), second look TURBT and early cystectomy or for muscle invasive bladder tumors, radical cystectomy or (oncologically subordinate) trimodal treatment with renewed TURBT, radiotherapy and chemotherapy are indicated. Possible complications of TURBT include bleeding with bladder tamponade, extraperitoneal or intraperitoneal bladder perforation and infections of the urogenital tract.

ABSTRACT

BACKGROUND: Water vapor thermal therapy (Rezum) is a minimally invasive treatment for benign prostatic enlargement (BPE). We report on safety and efficacy of this method for treatment of recurrent urinary retention and relief of catheter dependency owing to BPE in multimorbid patients, considered unfit for surgery. METHODS: We retrospectively evaluated 136 patients with recurrent urinary retention who underwent water vapor therapy in an ambulatory setting with periprostatic block and optional sedation between 11/2017 and 02/2021 in three urological departments. The objective was successful catheter withdrawal and continuing catheter independency after 3- and 12-months following treatment. RESULTS: Mean patient age was 80.3 years (±7.8), mean prostate volume 54 ml (±27.3), and mean catheter dependency before treatment was 4.8 months (±6.0). ASA classification was a followed: II: 10%, III: 71%, and IV: 19%. All procedures were performed successfully in an ambulatory setting. Perioperative complications were infrequent and minor (Clavien-Dindo Grade 1-2) and included haematuria in 4.4% and urinary tract infection in 3.9% of all cases. A total of 103 patients (78.6%) were able to void spontaneously after a median of 31 days. No significant differences in age, prostate volume, duration of catheter dependency, vapor injections, and ASA score were found between patients with successful or unsuccessful outcome. The mean follow-up period was 6.1 months (±5.9, range 1-22 months). A 3-month follow-up was available for 77 patients (75%) and 34 patients (33%) were followed for 12 months. After 3 and 12 months, 93.5 and 91% of patients remained catheter independent. Fifteen patients (11%) died during follow-up, with a mean overall survival of 7.7 months (±4.7). CONCLUSIONS: Water vapor therapy may prove to be a useful, minimally invasive treatment in a multimorbid population with catheter dependency after urinary retention, secondary to BPE, considered at highest risk or unfit for surgery. Future studies are warranted.

ABSTRACT

PURPOSE: Various techniques for EEP exist. They differ by surgical steps and the source of energy. It is assumed that the latter is of minor importance, whereas adherence to the anatomical enucleation template determines the postoperative result. So far, no systematic review highlights the differences between the energy sources in use for anatomical EEP. This study will address selfsame topic. METHODS: A systematic review of the literature was completed on September 1st, 2020. Studies comparing HoLEP, ThuLEP, DiLEP, or BipolEP with TUR-P providing 12 months of postoperative follow-up were included. Two frequentist network meta-analyses were created to compare the techniques of EEP indirectly. RESULTS: 31 studies, including 4466 patients, were found eligible for our meta-analysis. Indirect pairwise comparison showed differences in surgery time between BipolEP and HolEP (MD - 16.72 min., 95% CI - 27.75 to - 5.69) and DiLEP and HoLEP (MD - 22.41 min., 95% CI - 39.43 to - 5.39). No differences in the amount of resected prostatic tissue, major and minor complications and postoperative catheterization time were found. The odds for blood transfusions were threefold higher for BipolEP than for HoLEP (OR 3.27, 95% CI 1.02-10.5). The difference was not statistically significant when comparing prospective trials and matched-pair analysis only (OR 3.25, 95% CI 0.94-11.18). The Qmax 12 months after surgery was 2 ml/sec. higher for BipolEP than for DiLEP (MD 2.00, 95% CI 0.17-3.84) and 1.94 ml/sec. lower for DiLEP than for HoLEP (MD - 1.94, 95% CI - 3.65 to - 0.22). CONCLUSION: The energy source used for EEP has an impact on the intervention itself. BipolEP promotes surgical efficiency; laser techniques lower the risk of bleeding. REGISTRY: This meta-analysis is registered in the PROSPERO international prospective register registry with the registration number CRD42020205836.

ABSTRACT

PURPOSE: The aim of this retrospective study was to compare our initial experience with robotic assisted laparoscopic pyeloplasty (R-LPP) with the conventional laparoscopic method (C-LPP). MATERIALS AND METHODS: In the defined period from May 2015 to September 2019, a total of 76 renal pelvic surgeries were performed at two different university clinics. In all, 63 patients who received either L­NBP (n = 27) or R­NBP (n = 36) were considered for data analysis. RESULTS: The median follow-up for C­LPP and R­LPP was 22.5 and 12.7 months, respectively. The statistical analysis of the two groups revealed no statistically significant difference regarding age, body mass index, gender or affected side. The operating time was nonsignificantly shorter in the R­LPP group (180 ± 72 vs. 159 ± 54 min, p = 0.194). There were no statistically significant differences in postoperative pain, complications, average length of stay in hospital (7.48 ± 2.86 vs. 6.33 ± 2.04 days) or success rate. CONCLUSION: This study shows no significant reduction in operating time in the R­LPP group with an equal rate of complications. It could be shown that there is no disadvantage for the patients undergoing R­LPP directly after the implementation of a robotic system.

ABSTRACT

BACKGROUND: In an aging society an increase of benign prostatic obstruction (BPO) requiring treatment is to be expected and the proportion of patients with cardiovascular comorbidities under anticoagulation is also increasing. As the operative treatment of BPO can be problematic, the hemostatic effect of the techniques is of particular importance. OBJECTIVE: This review article discusses the data situation on the bleeding risk of established surgical techniques and the statement of the European Association of Urology (EAU) guidelines "EAU guidelines on management of non-neurogenic male lower urinary tract symptoms (LUTS), incl. benign prostatic obstruction (BPO)" on this topic. MATERIAL AND METHODS: Data analysis from PubMed. RESULTS: The EAU guidelines favor transurethral laser vaporization of the prostate using "greenlight", thulium or diode laser and laser enucleation using a holmium or thulium laser in this patient collective. The bipolar is superior to monopolar transurethral resection (TUR-P) in hemostasis. In the future bipolar enucleation of the prostate (BipoLEP) can be an alternative under good hemostasis. Bleeding is a rare complication after recently established minimally invasive techniques, such as Urolift®, I­TIND© and Rezum™, the same applies to prostate artery embolization. Aqua-ablation/AquaBeam® seems to be unsuitable due to frequent hematuria. Surgical adenomectomy can be associated with a high risk of bleeding. CONCLUSION: According to current data, transurethral laser vaporization and enucleation of the prostate are the treatment of choice for patients under anticoagulation; however, other transurethral techniques, such as BipoLEP have an acceptable risk of bleeding and can be an alternative depending on local resources. Newer minimally invasive approaches could become more important in the future.

ABSTRACT

Enhanced recovery after surgery (ERAS) protocols are widely established in adult urology, especially for cystectomies and procedures involving the (small) bowel. However, data concerning pediatric surgery and pediatric urologic surgery are scarce. Individual items of ERAS protocols have been well-studied and significant benefits have also been shown for children without increased risk of complications. In a number of small series the safety and efficacy of implementing ERAS protocols have been reported recently. A broad consensus and a guideline for a common pediatric ERAS protocol is not yet available.

ABSTRACT

PURPOSE: To investigate the morbidity, complication rate, and pain perception during removal of a novel ureteric stent with a magnetic end using a-traumatic retrieval catheter. METHODS: Between November 2013 and July 2015, 151 consecutive patients who underwent semirigid ureterorenoscopy (URS) for stone removal were prospectively enrolled. Stent removal was performed under local anesthesia using a special magnetic-end stent remover 1 week following URS. At follow-up, we obtained patients' medical history, urine culture result, renal ultrasonogram, and visual analog scale (VAS) score regarding stent irritation (VAS 1) and pain during removal (VAS 2). RESULTS: Pain perception during stent removal was significantly less painful in patients with a magnet stent than in those with a regular stent (p < 0.001). Stent irritation was slightly higher in patients with an indwelling magnet stent than in those with a regular stent (p < 0.001). No significant differences in stent irritations were found in patients who had a magnetic stent for 4 weeks after laparoscopic pyeloplasty (p = 0.20). Patients with a magnetic stent experienced significantly less pain during removal with a median VAS 2 score of 2.5 and a mean VAS 2 score of 2.58 [standard deviation (SD) ± 0.90] than those without a magnetic stent a median VAS 2 of 6 and a mean VAS 2 of 5.88 (SD ± 1.43). The stent length correlated with stent irritation (p = 0.05), and it significantly correlated with pain during removal (p < 0.001). CONCLUSION: The magnetic-end ureteric double-J stent is a safe option associated with less pain, particularly for male patients requiring short-term ureteric stenting.

ABSTRACT

BACKGROUND: Platinum-based systemic chemotherapy is considered the backbone for management of advanced urothelial carcinomas. However there is a lack of real world data on the use of such chemotherapy regimens, on patient profiles and on management after treatment failure. METHODS: Fifty-one randomly selected physicians from 4 European countries registered 218 consecutive patients in progression or relapse following a first platinum-based chemotherapy. Patient characteristics, tumor history and treatment regimens, as well as the considerations of physicians on the management of urothelial carcinoma were recorded. RESULTS: A systemic platinum-based regimen had been administered as the initial chemotherapy in 216 patients: 15 in the neoadjuvant setting, 61 in adjuvant therapy conditions, 137 in first-line advanced setting and 3 in other conditions. Of these patients, 76 (35 %) were initially considered as cisplatin-unfit, mainly because of renal impairment (52 patients). After platinum failure, renal impairment was observed in 44 % of patients, ECOG Performance Status ≥ 2 in 17 %, hemoglobinemia < 10 g/dL in 16 %, hepatic metastases in 13 %. 80 % of these patients received further anticancer therapy. Immediately after failure of adjuvant/neoadjuvant chemotherapy, most subsequent anticancer treatments were chemotherapy doublets (35/58), whereas after therapy failure in the advanced setting most patients receiving further anticancer drugs were treated with a single agent (80/114). After first progression to chemotherapy, treatment decisions were mainly driven by Performance Status and prior response to chemotherapy (>30 % patients). The most frequent all-settings second anticancer therapy regimen was vinflunine (70 % of single-agent and 42 % of all subsequent treatments), the main reasons evoked by physicians (>1 out of 4) being survival benefit, safety and phase III evidence. CONCLUSION: In this daily practice experience, a majority of patients with urothelial carcinoma previously treated with a platinum-based therapy received a second chemotherapy regimen, most often a single agent after an initial chemotherapy in the advanced setting and preferably a cytotoxic combination after a neoadjuvant or adjuvant chemotherapy. Performance Status and prior response to chemotherapy were the main drivers of further treatment decisions.

ABSTRACT

PURPOSE: To evaluate functional outcomes and morbidity rates after laparoscopic adenomectomy (LA) and Eraser laser enucleation of the prostate (ELEP). MATERIALS AND METHODS: Forty patients with lower urinary tract symptoms suggesting bladder outlet obstruction, with a prostate heavier than 70 g on transrectal ultrasound, were selected to undergo laparoscopic adenomectomy or Eraser laser enucleation of the prostate. All patients were consecutively enrolled without randomization and assessed preoperatively, 3 and 6 months postoperatively. Baseline characteristics, perioperative data, and postoperative outcomes were compared. RESULTS: The total operating time was significantly longer in the LA group (138.8 ± 11.4 vs. 78.4 ± 10.0 min, p < 0.000001). Catheter removal was performed earlier (61.2 ± 21.3 vs. 174.0 ± 13.2 h, p < 0.000001) and the hospital stay was significantly shorter (62.4 ± 21.2 vs. 187.2 ± 12.6 h, p < 0.000001) in the ELEP group. The latter group experienced significantly less perioperative hemoglobin (Hb) loss (0.71 ± 0.25 vs. 2.15 ± 1.08 g/dl, p < 0.000001), and their postoperative Hb levels (14.1 ± 1.21 vs. 11.7 ± 1.31 g/dl, p < 0.000001) were significantly higher. The resected tissue was significantly greater in the LA group (58.5 ± 23.3 vs. 87.9 ± 22.4 g, p = 0.0002). Significant improvements in Qmax, Qol, and symptom scores from baseline to each follow-up time point were noted in both groups. No statistically significant difference in symptom scores or Qmax was registered between the LA and the ELEP group throughout the follow-up period. CONCLUSION: Laparoscopic adenomectomy and ELEP were equally effective for relieving bladder outflow obstruction and lower urinary tract symptoms. The advantages of ELEP include less blood loss, shorter catheterization times, and shorter hospital stays.

ABSTRACT

UNLABELLED: BACKGROUND/AIMS/OBJECTIVES: To describe the depth of the laser coagulation zone in vivo based on histological examinations and the functional outcome of a 1,318-nm diode laser for enucleation in benign prostatic enlargement (BPE). METHODS: A total of 20 patients with BPE were treated by laser Eraser® enucleation of the prostate (ELEP). Prostatic tissue wedges were evaluated to assess the depth of the ELEP coagulation zones. Additionally, patients were assessed preoperatively and 12 months postoperatively. RESULTS: The coagulation zones were 0.36 ± 0.17 mm in epithelial tissue, 0.28 ± 0.15 mm in stromal tissue, and 0.25 ± 0.12 mm in mixed tissue. The coagulation area at the cutting edge completely sealed capillary vessels, reaching a depth of 0.35 ± 0.15 mm. The diameter of the coagulated vessels measured 1.75 ± 0.83 mm. Mean blood loss was 115.54 ± 93.12 ml, catheter time 1.35 ± 0.33 days, and hospital stay 1.89 ± 0.52 days. The International Prostate Symptom Score, maximal flow rate, and quality of life significantly improved 12 months after the procedure. CONCLUSIONS: ELEP is safe and effective for BPE treatment and yields good results at a follow-up of 1 year. Because of the limited penetration depth, damage to the urinary sphincter is not expected.

ABSTRACT

The functional and oncological results of laparoscopic retroperitoneal lymphadenectomy (L-RPLND) have proven to be as efficacious as open series (O-RPLND) after 5 year follow-up. In the most recent publication series from high-volume laparoscopy centres, there was a trend towards fewer complications in L-RPLND compared to O-RPLND. Up to now only two case series of four treated patients have been reported adopting a robotic-assisted retroperitoneal lymphadenectomy for testicular cancer so that it is not yet possible to judge whether it is useful tool or not.

ABSTRACT

OBJECTIVES: We evaluated children with pelvic kidney and their follow-up according to initial renal function and the appearance of concomitant urological pathologies. PATIENTS AND METHODS: In a retrospective analysis of our case notes, we studied 17 children (8 female, 9 male) who had been referred to our department for further investigation between 1994 and 2002 in whom we found a pelvic ectopic kidney. RESULTS: The mean age of the patients at the initial investigation was 72.5 months (range, 2 - 156 months); 10/17 were referred to our department for further investigation and clarification of a suspected renal agenesis, the remaining 7/17 children presented with urinary tract infection (1/17), nocturnal enuresis (3/17), hypertension (1/17) and phimosis (2/17). The nuclear medicine scan performed at the initial investigation in 14/17 children revealed that the function of the ectopic kidney had been reduced to one-third in contrast to two-thirds for the orthotopic kidney (p = 0.002). Overall global renal clearance was normal in all children. In 8/17 patients, the ongoing control nuclear investigations, on average 26.2 months later, revealed unchanged overall function of the kidney, we did, however, find a slight improvement of the ectopic renal function as compared to initial investigation which was not statistically significant (p = 0.683). In the period of this retrospective analysis, surgical correction of an accompanying pathology was performed in 23.5 % (4/17) of the children (vesico-ureteteric reflux operation in two cases, surgery for pelvic ureteric junction obstruction in one case, and nephroureterectomy in one case of a nonfunctioning-kidney). A left-sided pelvic kidney was seen in 64.7 % (11/17) of cases, a right-sided ectopic kidney in 23.5 % (4/17), a pelvic fused kidney in 11.7 % (2/17), and a solitary left-sided pelvic ectopia with right-sided agenesis in 5.8 % (1/17) of cases. CONCLUSION: In the event of suspected renal agenesis on ultrasonography, the possibility of a pelvic ectopic kidney should always be included in the range of diagnoses. On ultrasonography, the pelvic kidney is best visualized inferior to the iliac vessels, in the presence of a filled bladder. It is more frequently encountered on the left side. Nearly one-thirds of our patients presented with concomitant pathologies and one quarter needed surgical intervention. Although the function of the ectopic kidney alone was reduced by (2/3), the overall renal clearance was normal and remained stable in the course of the observation period.

ABSTRACT

AIM: To establish independent prognostic factors on a chromosomal basis in superficial bladder cancer, using a multicolour fluorescence in situ hybridisation (FISH) probe mix. PATIENTS AND METHODS: In 2002, voided urine from 75 consecutive patients (mean age 71.7, range 52-93) years under follow-up for superficial urothelial cancer was studied prospectively. The patients were observed for a mean (standard deviation (SD)) period of 39.3 (6.8) months (range 27-58) until July 2005. A multicolour FISH on liquid-based voided urinary cytology was carried out on all patients. Univariate analysis, using a log rank test, was used to determine the prognostic relevance of a low-risk pattern and a high-risk pattern. Progression-free survival time was calculated from the date of first diagnosis to first recurrence or progression according to the Kaplan-Meier product-limit method. RESULTS: One patient was lost to follow-up. 27 of the 74 remaining (36.8%) patients showed recurrent disease. In 9 (33.3%) patients with a low-risk pattern disease recurred after a mean (SD) observation time of 29.7 (1.9) months (range 8.3-52.3, median 30.8 (12.4)). 18 (66.7%) patients with a high-risk pattern developed recurrence within a mean (SD) of 17.6 (2.0) months (range 4-38.8, median 16.7 (11.6)). The Kaplan-Meier curve for progression-free survival showed marked differences between the low-risk and the high-risk groups. CONCLUSION: Patients with a high-risk chromosomal pattern have a markedly shorter disease-free survival time and higher progression rate than patients with a low-risk pattern. High-risk patients can therefore be treated more aggressively to prevent tumour spreading.

ABSTRACT

PURPOSE: The efficacy and durability of botulinum-A toxin in the treatment of detrusor hyperreflexia in myelomeningocele (MMC) children was evaluated prospectively. MATERIALS AND METHODS: A total of 15 children (10 male and 5 female, mean age 5.8 years), all on clean intermittent catheterisation (CIC) due to MMC, were "non responders" to orally and intravesically administered anticholinergic medication. Pretreatment assessment included a videourodynamic evaluation, incontinence scoring and a mercaptoacetyltriglycine-3 renal scan. We injected from 10 U/kg up to a maximum of 360 U botulinum-A toxin at 25-40 sites of the detrusor, sparing the trigone. Follow-up was 24 months. All children had a urodynamic reevaluation with assessment of bladder capacity and incontinence score at 3, 9 and 12 months. RESULTS: Mean bladder reflex volume increased from 72.00 +/- 28.12 ml to 298 +/- 32.45 ml (p < 0.001). The maximal detrusor pressure decreased from 78.76 +/- 23.14 cm H(2)O to 42.76 +/- 24.34 cm H(2)O (p < 0.001). Maximal bladder capacity increased from 136.34 +/- 45.71 ml to 297.02 +/- 87.17 ml (p < 0.001). Detrusor compliance increased from 18.29 +/- 27.19 ml/cm H(2)O to 51.17 +/- 38.17 ml/mmH(2)O (p < 0.001). While 10 patients became completely dry between CIC, the remaining 2 patients improved from score 3 to 1. Results at 9 months were similar to the ones at 3 months. The mean efficacy and durability of the toxin was 10.5 months after the first intravesical injection. CONCLUSIONS: Botulinum-A toxin is a safe alternative in the management of detrusor hyperreflexia in MMC children. Preliminary results are promising concerning urodynamic parameters and continence.

ABSTRACT

The aim of the study was to assess the value of liquid-based urinary cytology as a tool to perform uCyt+ and Multicolour-FISH in patients under follow-up after urothelial cancer. Therefore, standard cytology was compared to liquid-based cytology with the addition of the uCyt+ test, which traces the three monoclonal antibodies M344, LDQ10 and 19A211 in exfoliated urothelial cells; and Multicolour-FISH (including centromere-specific probes for chromosomes 3, 7, 17 and a locus-specific probe for 9p21/p16) performed on thin-layer specimens. UCyt+ showed an overall sensitivity of 86.2% and cytology of 45.0%. Overall sensitivity of both the tests combined was 90%. Sensitivity of Multicolour-FISH was 96.4%. All conventional cytology diagnoses were confirmed by liquid-based cytology. Liquid-based cytology is a valid tool for the performance of adjunctive analyses, such as uCyt+ and Multicolour-FISH, on residual cellular material.
