RESUMEN

PURPOSE: To describe trends and patterns of initial percutaneous nephrolithotomy (PCNL) and subsequent procedures from 2010 to 2019 among commercially-insured US adults with urinary system stone disease (USSD). METHODS: Retrospective study of administrative data from the IBM® MarketScan® Database. Eligible patients were aged 18-64 years and underwent PCNL between 1/1/2010 and 12/31/2019. Measures of interest for analysis of trends and patterns included the setting of initial PCNL (inpatient vs. outpatient), percutaneous access (1 vs. 2-step), and the incidence, time course, and type of subsequent procedures (extracorporeal shockwave lithotripsy [SWL], ureteroscopy [URS], and/or PCNL) performed up-to 3 years after initial PCNL. RESULTS: A total of 8,348 patients met the study eligibility criteria. During the study period, there was a substantial shift in the setting of initial PCNL, from 59.9% being inpatient in 2010 to 85.3% being outpatient by 2019 (P < 0.001). The proportion of 1 vs. 2-step initial PCNL fluctuated over time, with a low of 15.1% in 2016 and a high of 22.0% in 2019 but showed no consistent yearly trend (P = 0.137). The Kaplan-Meier estimated probability of subsequent procedures following initial PCNL was 20% at 30 days, 28% at 90 days, and 50% at 3 years, with slight fluctuations by initial PCNL year. From 2010 to 2019, the proportion of subsequent procedures accounted for by URS increased substantially (from 30.8 to 51.8%), whereas SWL decreased substantially (from 39.5 to 14.7%) (P < 0.001). CONCLUSIONS: From 2010 to 2019, PCNL procedures largely shifted to the outpatient setting. Subsequent procedures after initial PCNL were common, with most occurring within 90 days. URS has become the most commonly-used subsequent procedure type.

RESUMEN

Diabetes is a rising global health concern and an increasingly common cause of male infertility. Although the definitive pathophysiological mechanisms underpinning the association between diabetes and infertility is unclear, there are several animal studies showing diabetes to be a detrimental factor on reproductive health through apoptosis, oxidative stress and impairment of steroidogenesis. Furthermore, as reflected in animal models, antidiabetic strategies and relevant treatments are beneficial in the management of infertile men with diabetes as the recovery of euglycemic status affects positively the spermatogenesis. However, the available data are still evolving and specific conclusion in human populations are not possible yet. In this review, we are discussing the current literature concerning the association of diabetes and male infertility, focusing on the therapeutic approach as illustrated in animals' models.

RESUMEN

INTRODUCTION: The endoscopic resection of large and bulky bladder cancers represents a challenge. To reduce the tumor and make it more easy to resect, we used neoadjuvant short and intensive intravesical mitomycin (MMC) therapy. METHODS: Patients with large bladder tumors were evaluated for this study. At cystoscopy, the surgeon evaluated the feasibility of complete resection. In patients where this was not possible, biopsies from the tumor, bladder mucosa, and prostatic urethra were taken. These patients then underwent a short and intensive cytoreductive schedule of intravesical MMC. This was then followed by TUR-BT. RESULTS: Fifteen patients were included in our study. The mean age was 74 years (range: 56-82; SD ±6 years). Mean tumor size was 51 mm (range: 35-65; SD ±8 mm). After neoadjuvant treatment, complete resection was then feasible in all patients. The mean tumor volume after the chemo-resection had reduced to 34 mm (range: 10-50; SD ±13 mm). No adverse effects were reported. CONCLUSION: Intravesical cytoreductive neoadjuvant MMC as an initial treatment of large NMIBC can be considered safe, effective, and feasible.

RESUMEN

BACKGROUND: Hypospadia is one of the most common congenital anomalies in children. Patients with distal hypospadias can be treated successfully with a tubularized incised plate (TIP) urethroplasty, usually with a postoperative urethral stent to divert urine into the diaper or a urine bag for approximately 1 week. However, these stents have their own morbidity and complications. We therefore tried to determine the safety of distal penile hypospadias repair without the use of a postoperative stent. PATIENTS AND METHOD: Fifty patients with distal penile hypospadias were prospectively assessed from May 2016 to August 2018. All patients underwent Snodgrass urethroplasty by the same surgeon. Half of the patients had a postoperative stent for 1 week. The other half had no stent. Clinical follow-up was over 6 months with an emphasis on possible stent-related complications. RESULTS: Fifty children underwent TIP urethroplasty for distal hypospadia repair. The mean age was 5.9 years (range 2-12). In 25 cases, a stent was removed within 1 week. In the other 25 cases, no postoperative stent was placed. The overall complication rate for the stented group was 48% (n = 12) and for the non-stented group 68% (n = 17), respectively. In the stented group, 1 patient (4%) developed a fistula, whilst there were 2 (8%) in the non-stented group. All fistulas were repaired after 6 months postoperatively. Neourethral stenosis and glans dehiscence occurred in each 1 case (4%) in both groups. Differences were not statistically significant. However, there were significantly more wound infections in the stented group. On the other hand, stents prevented temporary urinary retention which occurred in 2 patients in the non-stented group. CONCLUSION: Despite the limited number of cases, our study suggests that, all in all, there is no significant difference in severe complication rates regardless whether a postoperative stent is used or not.

RESUMEN

Youssef's syndrome has been first described in 1957 as an atypical presentation of a vesicouterine fistula after lower segment Cesarean section. It is characterized by a triad of cyclic hematuria, amenorrhea, and absence of urinary incontinence, which is usually found in other forms of genitourinary fistulas. We describe a case report of a woman who developed a delayed Youssef's syndrome 3 months after her third Cesarean section. She was initially post-operatively treated conservatively and successfully for a bladder leakage through the wound with a bladder catheter for 1 month, and 2 months later, she developed symptoms as described above. She was successfully treated with uterus-sparing surgical fistula repair. Youssef's syndrome is a rare and atypical presentation. Physicians may easily be misled and diagnosis delayed. We describe the diagnostic approach and review the literature as to therapeutic approaches.

RESUMEN

OBJECTIVES: To evaluate Guy's Stone Score (GSS) as a grading system for the complexity of renal calculi before percutaneous nephrolithotomy (PCNL) and as a predictor for stone-free rate (SFR) and potential complications in the setting of a developing country with many cases of advanced complex stone disease. PATIENTS AND METHODS: We performed a prospective study on 115 patients with renal stones who had PCNL between August 2017 and October 2018. Stone complexity was classified according to GSS using preoperative imaging. The rates of perioperative complications were assessed using the Clavien grading system, and the SFR was assessed in the 3rd postoperative week by abdominal X-ray and renal ultrasound. The χ2 and one-way ANOVA tests were used for statistical analysis. A p value ≤0.05 was considered significant. RESULTS: The study included 115 patients (77 males) with a mean age of 50.2 (±13.3) years. Cases were classified according to GSS into 4 grades; there were 24 (20.9%) grade I, 48 (41.7%) grade II, 25 (21.7%) grade III, and 18 (15.7%) grade IV cases. There was a significant inverse correlation between GSS grade and SFR (p < 0.001). The rate of complications using the Clavien grading system were significantly higher in GSS grades III and IV (p = 0.002). So were the rates of blood transfusion, the need for >1 access tract, and the duration of hospitalization. CONCLUSION: GSS is a simple and easily reproducible system to classify the complexity of renal stones. In our setting, it also proved an excellent tool to predict SFR, perioperative complications, and associated ancillary procedures. Ultimately, it can help surgeons and, above all, patients to make a more informed decision about their surgery.

RESUMEN

INTRODUCTION: The success of upper urinary tract endoscopy on one hand and the high cost of purchase and maintenance of the scopes on the other hand have driven the development of disposable digital flexible ureterorenoscopy (fURS). MATERIALS AND METHODS: We performed an ex vivo comparison of 2 disposable digital fURS from different companies with a state-of-the-art reusable endoscope from another well-established scope manufacturer. The scopes were tested comparing parameters such as instrument handling, irrigation flow, image quality, and deflection. For the disposable scopes, the latter 2 were evaluated both, before and after vigorous stress testing. RESULTS: Expectedly, the most consistent finding among the 3 instruments was the marked decrease on irrigation flow following insertion of a working element, most notably a guidewire. Depth perception and ergonomic handling were comparable in all 3 instruments. Poststress testing revealed a significant loss of upward deflection in both disposable instruments, more so when an auxiliary instrument is inserted into the working channel. However, this did not appear to be the case in downward deflection. CONCLUSIONS: To our knowledge, this is the first study that used a vigorous stress testing protocol comparing disposable and reusable fURS. The newer generation disposable scope fared better than the older one. Results are encouraging and indicate that improvements are ongoing and progressing, bringing the quality of disposable scopes to the level that we are used to from our reusable high performance scopes while at the same time avoiding costly damage repairs. Continuous research and evidence-based interpretation of results in the absence of commercial bias are paramount to ensure this ongoing development.

RESUMEN

INTRODUCTION: Besides extracorporeal shockwave lithotripsy, semi-rigid ureteroscopy (URS) has become an equal therapy of choice for the treatment of most distal ureteric stones. Before the wide availability of laser lithotripsy as a tool for stone fragmentation, pneumatic lithotripsy was, and still is, widely used. In a country like Iraq, availability and affordability are the huge questions asked. Besides the capital investment for a laser machine, the pneumatic device is reusable, whereas the laser fibers are limited in their reusability. This makes pneumatic lithotripsy a more cost-effective option, at least in our setting. The question remains whether both options, compared in our setting with our limited resources, are equally effective and beneficial to our patients. PATIENTS AND METHODS: Fifty patients were included in our prospective study who underwent URS for the treatment of a distal ureteric stone. Half each (n = 25) underwent pneumatic (group A) or laser lithotripsy (group B). Inclusion criteria were a single distal ureteric stone measuring 7-20 mm in largest diameter, no anatomical abnormality, age >18 years, and an unsuccessful attempt of medical expulsion therapy. Patients with signs of urinary infection and pregnant women were excluded. All patients were operated upon under spinal anesthesia. Data recorded included operation time, stone size, type of scope and lithotripter, complications, hospital stay, and stone-free rate. RESULTS: Both groups did not show statistically significant differences in patient demography, stone size, operation time, complications, and stone-free rates (p > 0.05). CONCLUSION: Both pneumatic and Ho:YAG laser lithotripsy are equally effective and safe in treating distal ureteric stones in our setting. If the cost and availability of laser treatment is an issue, pneumatic lithotripsy is a viable and more cost-effective option.

RESUMEN

OBJECTIVES: To evaluate the safety and efficacy of percutaneous mini-nephrolithotomy (mini-PCNL) in children with complex staghorn stones. PATIENTS AND METHODS: We analyzed prospectively data of 28 children undergoing pediatric mini-PCNL during a period of 18 months. Stone complexity was defined according to the validated Guy's stone score (GSS). Our patients were GSS III and IV. All PCNL procedures were performed in the prone position, under fluoroscopic guidance, and in the same standardized fashion with F12 and F17 mini-nephroscopes. RESULTS: Eleven children were boys (total n = 28). Mean age was 7.25 ± 3.27 (2-14) years. Mean stone burden was 36.89 ± 8.002 (30-60) mm. GSS was in 57% grade III and in 43% grade IV. The initial stone-free rate was 78%, which increased to 89% after few ancillary procedures. Seventeen percent of children had major complications (1 hydrothorax, 4 blood transfusions). On statistical analysis, stone clearance rates were found inversely dependent on stone complexity (GSS; p < 0.025). Stone burden, number of tracts, and procedure time were associated with stone complexity (p < 0.000). In turn, stone complexity (p < 0.015) and the number of tracts (p < 0.049) were significantly associated with complications. CONCLUSION: Mini-PCNL is effective and safe for treating complex renal stones in pediatric patients. Complication rates are acceptable and predictably stable on comparison with the literature.

RESUMEN

AIM/OBJECTIVE: To identify trends in the evidence base regarding the effectiveness of using α-blockers in children versus adults and compare outcomes. METHODS: A literature search up using the key words including urolithiasis/renal/ureteric stone in children/paediatric population, medical expulsive treatment (MET), α-blocker/alfuzosin/tamsulosin/doxazosin. Included were randomized or controlled clinical trials in paediatric stone formers (aged ≤18 years). Outcome measures for assessment included the overall stone expulsion rate, expulsion time, the number of pain episodes and adverse drug effects and/or reactions. Further comparison of efficacy levels using respective studies from the adult population was performed in order to identify trends, similarities and differences. RESULTS: A total of 8,259 articles were identified. Full text evaluation was possible for 28 articles. Although the picture is clearer in the paediatric group, the lack of reproducible results in adults certainly poses serious questions about data collection, analysis and interpretation in each individual study. The apparent paradox is due to the methodological differences between studies. CONCLUSION: The effectiveness of α-blockers and other medication as MET needs to be studied in multi-institutional, double-blind, placebo-controlled studies that would aim to prove superiority to placebo in contemporary clinical situations, with realistic end points and standardized outcome measure determination.

RESUMEN

PURPOSE: The study aimed to assess the impact of the Memokath 051 stent (MK) on glomerular filtration rate (GFR) and split renal function in the management of ureteroileal anastomotic strictures. MATERIALS AND METHODS: We treated 6 patients in the ages of 66-77 years, 2 of whom had bilateral strictures, with a total of 8 ureteroileal strictures using the MK stent. Five patients had chronic kidney disease (CKD) prior to MK insertion. Mean time between conduit surgery and MK insertion was 28.4 months. Serum creatinine, GFR, and MAG-3 renography were determined before stent insertion and postoperatively at 3 months. RESULTS: Postoperative complications at 3-month follow-up included migration in 2 patients, occlusion in 2 patients, and urinary tract infection in 4 patients. The mean stent indwelling time was 353.4 ± 169.3 days. Mean preoperative creatinine, GFR, right, and left split renal function were 158.3 ± 76.3 µmol/L, 43.6 ± 32.9 mL/min/1.73 m2, 52.8 ± 22.2%, and 47.1 ± 22.2%, respectively. Mean postoperative values were 168.1 ± 84 µmol/L (p = 0.84), 40.8 ± 28.4 mL/min/1.73 m2 (p = 0.56), 51.1 ± 18.3% (p = 1), and 48.8 ± 18.3% (p = 1), respectively. CONCLUSION: MK stent is a safe and efficient minimally invasive long-term treatment option to preserve GFR in patients who develop CKD through ureteroileal anastomotic stricture. In spite of MK stent insertion and alleviation of obstruction, it was presumably inserted too late to improve renal function.

RESUMEN

Urolithiasis is a significant worldwide source of morbidity, constituting a common urological disease that affects between 10 and 15% of the world population. Recent technological and surgical advances have replaced the need for open surgery with less invasive procedures. The factors which determine the indications for percutaneous nephrolithotomy include stone factors (stone size, stone composition, and stone location), patient factors (habitus and renal anomalies), and failure of other treatment modalities (ESWL and flexible ureteroscopy). The accepted indications for PCNL are stones larger than 20 mm2, staghorn and partial staghorn calculi, and stones in patients with chronic kidney disease. The contraindications for PCNL include pregnancy, bleeding disorders, and uncontrolled urinary tract infections. Flexible ureteroscopy can be one of the options for lower pole stones between 1.5 and 2 cm in size. This option should be exercised in cases of difficult lower polar anatomy and ESWL-resistant stones. Flexible ureteroscopy can also be an option for stones located in the diverticular neck or a diverticulum. ESWL is the treatment to be discussed as a option in all patient with renal stones (excluding lower polar stones) between size 10 and 20 mm. In addition, in lower polar stones of size between 10 and 20 mm if the anatomy is favourable, ESWL is the option. In proximal ureteral stones, ESWL should be considered as a option with flexible ureteroscopy Active monitoring has a limited role and can be employed in post-intervention (PCNL or ESWL) residual stones, in addition, asymptomatic patients with no evidence of infection and fragments less than 4 mm can be monitored actively.

RESUMEN

Pseudoaneurysm following flexible ureterorenoscopy has not been reported so far. The etiology remains unclear as high intra-renal pressure, direct laser damage and damage through stiff guidewire puncture had all been avoided. We like to share this case to make urologists aware of this unusual complication and discuss possible causes and therapeutic approaches.

RESUMEN

PURPOSE: Among the different types of kidney stones, matrix stones are uncommon urinary calculi composed of a soft, pliable, amorphous substance with little crystalline content. To gain insight into the pathogenesis we investigated the protein component by analyzing the proteomic profiles of surgically removed matrix stones. MATERIALS AND METHODS: A total of 5 stones were harvested from 4 patients who underwent surgery for medical reasons at 3 clinical centers during a 7-year period. Matrix stone proteome characterization was performed by mass spectrometry based techniques using an integrated top-down/bottom-up proteomic platform. RESULTS: We identified 142 nonredundant proteins and peptides across all samples. Neutrophil defensin 1, and proteins S100-A8 and S100-A9 were the main components of these renal calculi. CONCLUSIONS: The abundance of identified inflammatory molecules points to an inflammatory process as the event that initializes soft calculi formation rather than as a consequence of such formation. The post-translational oxidative changes in S100-A8 and A9, and the presence of thymosin ß-4, granulins and ubiquitin also suggest the intervention of host defenses through a superimposed, vigorous counter inflammatory process. The post-translational changes seen in the proteins and peptides, and the known self-assembling capability of S100-A8 and S100-A9 probably explain the gelatinous consistency of these stones.

RESUMEN

OBJECTIVE: In spite of readily available evidence-based guidelines on urolithiasis treatment, practical applications of treatments vary from country to country, or even within countries. The choice of treatment depends not only on the evidence, but often on general non-medical decision factors such as infrastructure, expertise, trends, patient demands, industry drive and reimbursement levels. In turn, many of these factors are interdependent and a result of the individual National Health System. METHOD: In an attempt to get a crude picture of trends and practices in stone treatment across Europe, a group of well-renowned international experts in the field were asked to reply to a set of standard questions relating to stone treatments, health systems and adherence to guidelines (level of evidence D = expert opinion). RESULTS: The above-mentioned interdependencies showed a varying picture in different countries. Overall, there is a trend away from lithotripsy and toward ureterorenoscopy. However, the choice of treatment is largely dependent on the affordability of infrastructure. Urologists may make choices based on the national reimbursement system, too. CONCLUSION: Without claiming to represent a scientifically sound study, this survey represents an interesting insight into a representative cross-section of European urological current practices and trends in urolithiasis treatment.

RESUMEN

INTRODUCTION: Calcification of the vas deferens and seminal vesicles is a rare condition of unknown incidence. It has been described in association with diabetes, hyperparathyroidism and genitourinary tuberculosis, amongst other conditions. Little is known about the clinical significance and management of this condition. We review the literature in an effort to find answers about an entity that is frequently appreciated as an incidental finding. MATERIALS AND METHODS: An electronic database search was performed (Medline) using the key words: vas deferens; seminal vesicles; calcification, alone or in combination. Articles were selected according to relevance and quality of evidence. RESULTS: The search included published manuscripts between 1960 and 2012. A total of 17 relevant publications were identified. The majority were written in the English language and mostly consisted of case presentations and reports of radiologic findings. CONCLUSION: Calcification of the vas deferens and seminal vesicles is a rare condition. However, it may be implicated in male factor infertility and symptoms from the urogenital tract. Treatment should be directed towards the underlying cause on an individual basis. It is unknown whether control of the primary process has any effects on the histopathological appearance of the ducts and/or their improvement of function.

RESUMEN

PURPOSE: The Post-Ureteroscopic Lesion Scale (PULS) offers a simple grading system for the description of ureteral lesions after ureteroscopy. In this article, we present the results of a video-based multicenter evaluation of the inter-rater reliability of clinically important PULS grades 0-3. METHODS: Video sequences at the end of ureteroscopy (final passage) were recorded for 100 consecutive patients at a single institution and assessed by experienced urologists (n = 20) and senior residents (n = 17) at 19 international centers. The cohort included only patients with lesions grades 0-3 (with grades 2 and 3 subsumed as 2 + since distinction is defined by an extravasation of contrast medium in fluoroscopy). The gradings were evaluated for inter-rater reliability and in terms of simplicity, validity, comprehensibility, reproducibility, and usefulness. RESULTS: Overall, inter-rater reliability was high (Kendall's W = 0.69, p < 0.001) and was comparable between specialists (Kendall's W = 0.69, p < 0.001) and residents (Kendall's W = 0.71, p < 0.001). The matched ratings showed grade 0 in 43.0 % of patients and grades 1 or 2 + in 44.0 and 13.0 % of patients, respectively. Results of the questionnaires indicated a high degree of acceptance, with an overall rating of 1.76 (1.64-1.93 for different items, scale 1-6). CONCLUSIONS: Inter-rater reliability of the endoscopically assessable PULS was high among urologists with different levels of experience in different countries worldwide. The validated PULS system may be used for standardized reporting of ureteral lesions/injuries after ureteroscopy. In addition, PULS will enable more selective standardization of indications for postoperative DJ stenting based on the randomized controlled trials.

RESUMEN

OBJECTIVE: To investigate the evidence for the use of hyoscine N-butylbromide (HBB) in the treatment of acute renal colic. METHODS: A literature search was performed using the keywords 'hyoscine N-butylbromide', 'ureteral colic', 'spasmolytic', 'anticholinergic' and 'analgesia'. The articles were given the appropriate level of evidence according to the Oxford Centre for Evidence-Based Medicine Levels of Evidence guidelines. RESULTS: The analgesic effect of HBB as monotherapy is inferior to that of opioids and/or non-steroidal anti-inflammatory drugs (NSAIDs). It does provide an analgesic and antispasmodic effect, but not as long-lasting as NSAIDs. HBB does not serve as an adjunct to opioids. Furthermore, it does not facilitate passage of ureteral stones and has no effect on expulsion rate. CONCLUSIONS: HBB is often used where urinary tract smooth muscle spasm is thought to be part of the pathophysiological process. According to the evidence, administration of HBB follows non-peer-reviewed protocols which are based on empiric recommendations. Its role is still unclear, as it appears to have no advantage when used as monotherapy over established forms of analgesia. There appears to be a time-dependent relation to pain reduction following parenteral administration, but this needs to be confirmed by more prospective randomized cohorts.

RESUMEN

OBJECTIVE: To validate and evaluate the applicability of a new score to describe postsurgical analgesic consumption in urological and surgical patients across different categories of pain medications and the invasiveness of medical interventions. MATERIALS AND METHODS: The cumulative analgesic consumption score (CACS) was determined for two cohorts of patients split into three groups with surgeries involving clinically distinct levels of invasiveness (n = 2 x 60). Nonparametric statistical analyses were performed to determine differences between the CACS among the different groups and to assess the correlation between CACS and numeric rating scale (NRS) values for pain intensity. RESULTS: The score was determined for postoperative days 1 and 2 and revealed median scores of 0 (0-11), 3 (0-22) and 10 (6-17) for UA (urological patients from group A), UB (group B) and UC (group C), respectively, and 4 (0-20), 8 (0-38) and 17 (7-68) for SA (surgical patients from group A, SB (group B) and SC (group C), respectively. CACS enabled reliable differentiation between groups involving different levels of invasiveness (p < 0.001). CACS and peak NRS values showed variable degrees of correlation, as expressed by levels of significance ranging from p < 0.001 to p = 0.34 (NS). CONCLUSIONS: The CACS is a valid and easily applicable tool to describe postsurgical analgesic consumption in urological and surgical patients. It can be used as a surrogate parameter to assess postsurgical pain and the invasiveness of surgical procedures. These aspects may be measured to compare surgical procedures, in both clinical trials and clinical practice settings.

RESUMEN

INTRODUCTION: Benign Prostate Hyperplasia (BPH) significantly impacts men's health and quality of life, with its prevalence rising with age. This review critically examines the cost-effectiveness of pharmacological interventions for BPH to optimize patient outcomes and healthcare resource utilization. AREAS COVERED: This review explores the integration of cost-effectiveness analysis (CEA) into clinical practice, balancing clinical efficacy with economic efficiency in BPH management. We performed a critical literature search, including recent studies on the economic evaluation of BPH treatments, focusing on pharmacotherapies such as alpha-blockers and 5-alpha reductase inhibitors. Additionally, we discussed the concept of CEA and evaluated the role of medicinal reconciliation and the avoidance of polypharmacy in favor of optimal BPH treatment. EXPERT OPINION: Cost-effectiveness analysis is crucial for evaluating BPH treatments, with evidence suggesting a shift towards surgical interventions may offer greater long-term economic benefits. However, these models must be applied cautiously, considering clinical evidence and patient preferences to ensure equitable and patient-centric healthcare.
