Prevalence and Clinical Case Series of Syndromic and Nonsyndromic Cleft Lip and Palate in a Saudi Arabian Neonatal Population.

OBJECTIVE: To report clinical case series of cleft lip with or without palate (CL/P) and to estimate the prevalence of infants with CL/P who were syndromic or nonsyndromic. DESIGN: This is a clinical case series study of CL/P among live births in the maternity hospital. SETTING: The study was carried out in Maternity and Children Hospital, Najran between January 2013 and December 2016. MATERIALS AND METHODS: Sex and clinical presentation of CL/P were collected from the medical records of live births. Clinical presentations were identified by type of CL/P and stratified according to laterality of occurrence. The data were analyzed using (SPSS) program, version 20. Results were presented in simple descriptive statistics. MAIN OUTCOME: Prevalence of CL/P in the Najran region of Saudi Arabia was 0.65 per 1000 live births (95% CI: 0.650 [0.389-1.092]). Cleft lip and palate was the commonest clinical presentation. RESULT: Of 24 367 live birth, 16 were classified as having CL/P. The overall frequency of CL/P was 0.65/1000 live births (95% CI: 0.650 [0.389-1.092]). There were 10 males and 5 females. Infant sex cannot be established in 1 case. Two (12.5%) patients had cleft lip, 4 (25%) had isolated cleft palate, and 10 (62.5%) had combined CL/P. Nine (56.25%) neonates were cases of nonsyndromic CL/P, while 7 (43.75%) were cases of syndromic CL/P. CONCLUSIONS: Prevalence rate of 0.65 per 1000 live births over 4-year period was observed at (95% CI: 0.650 [0.389-1.092]). Cleft lip with or without palate was the commonest clinical presentation.

Intraoperative blood transfusion in pediatric patients undergoing renal transplant-Effect of renal graft size.

In pediatric RT, donor allograft size often exceeds the expected recipient norms, especially in younger recipients. An "oversize" graft might not only present a technical- and space-related challenge, but may possibly lead to increased demands in perioperative volume requirements due to the disparity between donor and recipient in renal blood flow. We evaluated transfusion practices at a single tertiary institution with special consideration of kidney graft size, hypothesizing that oversize graft kidneys might lead to a quantifiable increased need of blood transfusion in smaller recipients. Retrospective analysis of all patients who underwent pediatric RT from January 2004 to June 2014 at a tertiary pediatric centre was performed. Variables analyzed included patient age, weight, pre- and postoperative Hb concentration, graft size, EBL, amount of intraoperative blood transfusion, and preoperative use of erythropoietin. Based on graft size in relation to patient's age, a SMR and an OvR were identified. A subcohort of age-matched pairs was used to allow for comparison between groups. We calculated the expected procedure- and transfusion-induced changes in Hb and compared these changes to the observed difference in pre- vs postoperative Hb to assess the influence of graft size on transfusion requirements. RT was performed in 188 pediatric recipients during the study period. In the matched cohort, percentage of transfused patients during transplantation in the OvR group was more than double compared with SMR (89% vs 39%, P < .001); similarly, the median number of transfused PRBC units in OvR was 1, while the median of SMR did not receive transfusion (P < .001). The difference between expected (calculated) and observed change in Hb was significantly higher in OvR with a median of 1.9 g/dL compared with SMR with a median of 1.0 g/dL (P = .026). Correspondingly, the calculated median volume taken up by a regular size kidney was significantly higher with 213 mL compared with 313 mL (P = .031) taken up by an oversize graft kidney. Median estimated intraoperative blood loss was significantly higher in OvR than in SMR (6.9 mL/kg, vs 5.3 mL/kg, respectively; P = .04). Median postoperative Hb was similar among groups (10.4 g/dL vs 10.6 g/dL for SMR vs OvR, respectively). Transplantation of an oversized kidney in pediatric RT recipients is associated with a quantifiable higher need for blood transfusion. This may be caused by a higher intraoperative EBL and/or greater blood volume sequestered by the larger renal allograft and requires further evaluation.

Side-to-Side Refluxing Nondismembered Ureterocystotomy: A Novel Strategy to Address Obstructed Megaureters in Children.

PURPOSE: A nonrefluxing megaureter is a relatively common cause of antenatal hydronephrosis. Although nonoperative management is favored, surgical intervention is sometimes warranted. However, there is controversy regarding the best approach, particularly in young children. We describe our experience with nondismembered side-to-side refluxing ureterocystotomy as a simple option to address obstruction. MATERIALS AND METHODS: Between January 2012 and January 2017, 32 patients underwent ureterocystotomy at 4 referral centers in North America. Demographics, surgical indications, complications, need for further interventions and change in hydronephrosis were captured. Patients were monitored clinically and with serial ultrasounds. RESULTS: Mean age at surgery was 3.7 months (range 0 to 33) and 25 (78%) patients were male. Unilateral procedures were performed in 29 patients. All patients were initially identified based on the presence of antenatal hydronephrosis and symptoms developed in 10. The procedure was conducted for primary nonrefluxing megaureter in 27 patients and to address secondary obstruction in the remainder. Mean followup was 34.3 months (range 6 to 58). At the most recent evaluation most children demonstrated significant improvement in dilation (86%). To date, 6 patients have undergone further procedures, including a circumcision and 2 ureteral reimplantations for recurrent infections. CONCLUSIONS: Our results suggest that side-to-side refluxing ureterocystotomy is a straightforward, minimally invasive alternative for the surgical management of nonrefluxing megaureter. Despite the trade-off of relieving obstruction and creating reflux, it can be considered a potentially definitive procedure in patients who remain infection-free, particularly circumcised boys. Extended followup with close monitoring is critical to document long-term results with this intervention.

Intra-arterial nitroglycerin for intra-operative arterial vasospasm during pediatric renal transplantation.

Intra-operative arterial vasospasm during pediatric renal transplantation is an urgent clinical situation resulting in end-organ ischemia, associated changes in parenchymal turgor and color, diminished flow on ultrasound, and if left untreated, allograft loss. We hypothesized that intra-operative intra-arterial injection of nitroglycerin would reverse vasospasm and improve renal perfusion. A three-yr-old girl with end-stage renal disease due to autosomal recessive polycystic kidney disease on peritoneal dialysis underwent deceased donor renal transplantation. After optimal immediate reperfusion and hemodynamic parameters, the kidney lost turgor and became mottled in appearance despite adequate hilar arterial and venous Doppler waveforms. Two aliquots of 40 µg (0.4 mL of a 100 µg/mL) nitroglycerin solution were injected directly into the renal artery 10 min apart. Nitroglycerin resulted in dramatic change in the consistency and appearance of the allograft. An improvement in renal blood flow was demonstrated by ultrasound after the second intra-arterial nitroglycerin injection with only a transient decrease in systemic arterial blood pressure. The child experienced normal allograft perfusion on serial postoperative ultrasounds, with a prompt decrease in serum creatinine and excellent diuresis. Intra-arterial nitroglycerin is a promising option for intra-operative arterial vasospasm during pediatric renal transplantation with objective improvement in blood flow and perfusion.

Novel Strategy for Temporary Decompression of the Lower Urinary Tract in Neonates Using a Ureteral Stent.

PURPOSE: In children with congenital obstructive uropathy, including posterior urethral valves, lower urinary tract decompression is recommended pending definitive surgical intervention. Current options, which are limited to a feeding tube or Foley catheter, pose unappreciated constraints in luminal diameter and are associated with potential problems. We assess the impact of luminal diameter on the current draining options and present a novel alternative method, repurposing a widely available stent that optimizes drainage. MATERIALS AND METHODS: We retrospectively reviewed patients diagnosed with posterior urethral valves between January 2013 and December 2014. In all patients a 6Fr 12 cm Double-J ureteral stent was advanced over a guidewire in a retrograde fashion into the bladder. Luminal flow and cross-sectional areas were also assessed for each of 3 tubes for urinary drainage, ie 6Fr Double-J stent, 5Fr feeding tube and 6Fr Foley catheter. RESULTS: A total of 30 patients underwent uneventful bedside Double-J stent placement. Mean ± SD age at valve ablation was 28.5 ± 16.6 days. Mean ± SD peak serum creatinine was 2.23 ± 0.97 mg/dl after birth and 0.56 ± 0.22 mg/dl at the procedure. Urine output after stent placement was excellent in all patients. The Foley catheter and feeding tube drained approximately 18 and 6 times more slowly, respectively, and exhibited half the calculated cross-sectional luminal area compared to the Double-J stent. CONCLUSIONS: Use of Double-J stents in neonates with posterior urethral valves is a safe and effective alternative method for lower urinary tract decompression that optimizes the flow/lumen relationship compared to conventional drainage options.

Prevalence of nocturnal enuresis among children of Aseer region in Saudi Arabia.

Introduction: Nocturnal enuresis (NE) in children is a very common problem managed in pediatric urology. In this study, we present the prevalence of NE in children in Aseer region in Saudi Arabia. Methodology: This study was conducted as a descriptive cross-sectional survey to estimate the prevalence of NE among 555 Saudi children aged 5-15 years in Aseer region in Saudi Arabia. Data collection was done through a questionnaire, which included questions on sociodemographic data, personal knowledge, enuresis-related characteristics, risk factors, and management modalities. Results: This study identified a prevalence of enuresis of 24% of the study population, most of whom were boys. The majority of the parents had a high educational level. Clinical characteristics of the study population showed: 9% have a family history of NE, 2.2% have a history of neurological disorder, 10.0% have a history of urinary tract infections, 66.8% have associated daytime urgency, 67% have urine-holding behavior, and 19.5% have associated daytime enuresis of the study population. Conclusion: Our study found that 24% of children in the Aseer region in Saudi Arabia have NE. Our study finding helps us to understand the prevalence of NE in Aseer region in Saudi Arabia, and this can be applied to other regions in the kingdom. Furthermore, this finding helps us to understand the need to raise awareness in the community about NE and the need to educate the nonpediatric urologist health-care provider about the best management practice for NE.

A magnetic mass within the bladder.

A search of the literature finds that there have been many case reports documenting a wide array of objects found within the bladder, ranging from magnets and paper clips to telephone and aluminum wire. The goal of treatment is to remove the object quickly, using the least invasive method possible. Therefore, the ideal treatment is removal through endoscopic means; however, in some cases, the size, mobility and shape of the foreign body can prevent its removal endoscopically and more invasive means must be employed. We present a case of a patient who inserted 150 magnetic spherical beads into his bladder.

Enhanced fluid drainage using a novel multi-pod drainage catheter: An in vitro evaluation.

BACKGROUND: A multi-pod catheter (MPC) is a large drainage catheter that can house multiple smaller retractable (MPC-R) and deployable catheters (MPC-D) within the body. OBJECTIVE: The drainage capabilities and resistance to clogging of a novel MPC have been assessed. METHODS: The drainage capabilities are evaluated by placing the MPC in a bag of either a non-clogging (H2O) or clogging medium. The results are then compared to matched-size single-lumen catheters with either a close (CTC) or open tip (OTC). The means of five test runs were used to measure drainage rate, maximum drained volume (MaxDV), and time to drain the first 200 mL (TTD200). RESULTS: In the non-clogging medium, MPC-D had a slightly higher MaxDV than MPC-R, and higher flow rate than CTC and MPC-R. Moreover, MPC-D needed less TTD200 than MPC-R. In the clogging medium, MPC-D had a higher MaxDV than CTC and OTC, higher flow rate, and faster TTD200 than CTC. However, comparison with MPC-R showed no significant difference. CONCLUSION: The novel catheter may offer superior drainage compared to the single-lumen catheter in a clogging medium, implying various clinical applications, particularly when clogging is a potential risk. Further testing may be required to simulate various clinical scenarios.

The Analysis of Job Satisfaction of Health Practitioners in Saudi Arabia: Determinants and Strategic Recommendations for Health Workforce Planning.

BACKGROUND: Job satisfaction plays an important foundation in the health system to deliver high-quality care services to patients. Job satisfaction describes the inside feeling of workers about their jobs whether they like it or not. Job satisfaction of health practitioners is considered an essential factor that affects their efficiency, well-being, and mental health. AIM: This research study is part of an integrated research aiming to understand the determinants of a revised Workforce Planning Strategy in Saudi Arabia, in close relevance to the demand and supply side in Saudi Arabia. RESULTS: This study showed that males were significantly more satisfied than females in relation to specialty, organization, and overall global score. There is also evidence for a significant association between age groups and job satisfaction. Older health practitioners had a higher level of satisfaction than younger ones. Regarding nationality, we found that Saudi health practitioners were less satisfied in all aspects, while non-Saudi (Arab) healthcare practitioners were the most satisfied in all aspects except city happiness. CONCLUSION: Our study found statistically significant differences that medicine and surgery practitioners are the most satisfied professionals and the least satisfied are dentist practitioners. Health practitioners with more than five years of experience were significantly the most satisfied.

Malignant testicular tumors in children: overview on 10 years of Saudi Cancer Registry.

BACKGROUND/OBJECTIVE: The aim of this study was to identify epidemiological and histopathological patterns of pediatric testicular tumor (TT) in Saudi population over 10 years. METHODS: Retrospective data extracted from the Saudi Cancer Registry for Saudi children diagnosed with TT from 2008 to 2017. The data collected included patient's factors as age, year of diagnosis, survival status, and tumor factors as basis of diagnosis, origin of the tumor, histopathological group and subtype, and tumor behavior, stage, and laterality. RESULTS: A total of 115 patients with a median age of 14 (IQR 1.5-17) were included. The primary tumor site was a normal descended testis in 98.3% (115). Yolk sac tumor was the most common 28.2% (33), followed by embryonal carcinoma in 27.4% (32) and mixed germ-cell tumors in 23.1% (27). Kaplan-Meier analysis revealed significant association between survival and the stage of the tumor (p = 0.002). However, there was a lack of significant association between survival and age groups, histopathological groups, and histopathological subtypes (p = 0.541, p = 0.609, and p = 0.733, respectively). The overall mortality rate of TT 5.2% with all deaths caused by non-seminomatous germ-cell tumor diagnosed with stage 3. CONCLUSIONS: The median age of the patients was 14 years. Yolk sac tumors were the most common while testicular choriocarcinomas were the least in incidence. No increase in the incidence of TT was seen and the mortality rate over the 10-year period was 5.2%. Shorter survival was associated with higher tumor stage.

Urinary tract infection in children: A narrative review of clinical practice guidelines.

Background: Urinary tract infection (UTI) has been a major burden on the community and the health-care systems all over the globe. It is the most common cause of bacterial infection in the pediatric age group, with an annual incidence of 3%. The aim of this study is to review and summarize all available guidelines on the diagnosis and management of children with UTI. Materials and Methods: This is a narrative review of the management of children with a UTI. All biomedical databases were searched, and any guidelines published from 2000 to 2022 were retrieved, reviewed, and evaluated to be included in the summary statements. The sections of the articles were formulated according to the availability of information in the included guidelines. Results: UTI diagnoses are based on positive urine culture from a specimen of urine obtained through catheterization or suprapubic aspiration, and diagnoses cannot be established on the bases of urine collected from a bag. The criteria for diagnosing UTI are based on the presence of at least 50,000 colony-forming units per milliliter of a uropathogen. Upon confirmation of UTI, the clinician should instruct parents to seek rapid medical assessment (ideally within 48 h) of future febrile disease to ensure that frequent infections can be detected and treated immediately. The choice of therapy depends on several factors, including the age of the child, underlying medical problems, the severity of the disease, the ability to tolerate oral medications, and most importantly local patterns of uropathogens resistance. Initial antibiotic choice of treatment should be according to the sensitivity results or known pathogens patterns with comparable efficacy of oral and parenteral route, for 7 days to 14 days duration. Renal and bladder ultrasonography is the investigation of choice for febrile UTI, and voiding cystourethrography should not be performed routinely unless indicated. Conclusion: This review summarizes all the recommendations related to UTIs in the pediatric population. Due to the lack of appropriate data, further high-quality studies are required to improve the level and strength of recommendations in the future.

Saudi patient knowledge and awareness regarding smoking as a risk factor for urological diseases.

AIM: Our aim was to evaluate Saudi patient knowledge and awareness regarding smoking as a risk factor for bladder cancer, kidney cancer, and erectile dysfunction (ED). SETTINGS AND DESIGN: This quantitative cross-sectional study was conducted across three major tertiary hospitals in Riyadh, the capital city of Saudi Arabia. MATERIAL AND METHODS: A self-administered questionnaire was distributed to 539 patients in the urology outpatient clinic. STATISTICAL ANALYSIS: Data were analyzed using the Statistical Package for the Social Studies 21.0. For descriptive statistics, the frequency was calculated for all study variables. Chi-squared test was used for categorical variables. P < 0.05 was considered statistically significant. RESULTS: A total of 539 urological patients completed the questionnaire. There were 460 (85.4%) male and 79 (14.6%) female respondents. Only 60.9%, 41.2%, and 36.9% of participants were aware that smoking was a risk factor for ED, kidney cancer, and bladder cancer, respectively. CONCLUSIONS: The knowledge and awareness were low among urological patients regarding smoking as a risk factor for urological diseases.

Saudi Urological Association consensus guidelines on the use of robotic surgery in urology.

Over the past three decades, minimally invasive robotic technology has evolved substantially in urological practice, replacing many open procedures and becoming part of routine clinical practice. The Health Sector Transformation Program for the Kingdom's Vision 2030 aims to restructure the health sector and optimize its status and prospects as an effective and integrated ecosystem centered on the patient's health. Therefore, this consensus seeks to endorse the clinical practice guidelines for robotic surgery (RS) in the KSA, highlighting its effectiveness, safety, and favorable outcomes compared to open and laparoscopic surgeries in certain procedures when used by trained surgeons in well-structured RS programs.

Randomized trial of prophylactic antibiotics vs. placebo after midshaft-to-distal hypospadias repair: the PROPHY Study.

BACKGROUND: Use of prophylactic antibiotics after stented hypospadias repair is very common, but most research has not identified any clinical benefits of this practice. Only one study has found that postoperative prophylaxis reduces symptomatic urinary tract infections (UTIs). Data from the same trial suggested that prophylaxis may also reduce urethroplasty complications. No studies on this subject have been placebo-controlled. OBJECTIVE: We performed a randomized, double-blind, placebo-controlled study to evaluate the effect of postoperative prophylactic antibiotics on the incidence of infection or urethroplasty complications after stented repair of midshaft-to-distal hypospadias. STUDY DESIGN: Boys were eligible for this multicenter trial if they had a primary, single-stage repair of mid-to-distal hypospadias with placement of an open-drainage urethral stent for an intended duration of 5-10 days. Participants were randomized in a double-blind fashion to receive oral trimethoprim-sulfamethoxazole or placebo twice daily for 10 days postoperatively. The primary outcome was a composite of symptomatic UTI, surgical site infection (SSI), and urethroplasty complications, including urethrocutaneous fistula, meatal stenosis, and dehiscence. Secondary outcomes included each component of the primary outcome as well as acute adverse drug reactions (ADRs) and C. difficile colitis. RESULTS: Infection or urethroplasty complications occurred in 10 of 45 boys (22%) assigned to receive antibiotic prophylaxis as compared with 5 of 48 (10%) who received placebo (relative risk [RR], 2.1; 95% confidence interval [CI], 0.8 to 5.8; p = 0.16). There were no significant differences between groups in symptomatic UTIs, SSIs, or any urethroplasty complications. Mild ADRs occurred in 3 of 45 boys (7%) assigned to antibiotics as compared with 5 of 48 (10%) given placebo (RR, 0.6; 95% CI, 0.2 to 2.5; p = 0.72). There were no moderate-to-severe ADRs, and no patients developed C. difficile colitis. CONCLUSIONS: In this placebo-controlled trial of 93 patients, prophylactic antibiotics were not found to reduce infection or urethroplasty complications after stented mid-to-distal hypospadias repair. The study did not reach its desired sample size and was therefore underpowered to independently support a conclusion that prophylaxis is not beneficial. However, the result is consistent with most prior research on this subject. GOV IDENTIFIER: NCT02096159.

The status of medical malpractice litigations in Saudi Arabia: Analysis of the annual report.

CONTEXT: Medical malpractice is a leading cause of morbidity and mortality worldwide. Analyzing the current number of lawsuits and comparing it to previous years will help assess the status of medical malpractice litigations in Saudi Arabia. SUBJECTS AND METHODS: A review and analysis of the annual statistics book of the Medico-Legal Committees (MLCs) in Saudi Arabia over the years (1437-1439 H) was conducted. RESULTS: Over the 3-year study period, the total number of lawsuits was 3,684. The percentage of increase of malpractice lawsuits from 1437 until 1439 Hijri (2016-2018) was 26% (1,097-1,379 lawsuits). Obstetrics and Gynecology consistently had the highest number lawsuits compared to other specialties (25.6%), followed by dentistry (13.5%). Similarly, the rate of compensation after a lawsuit was highest in Obstetrics and Gynecology claims (62.7%), followed by dentistry (60%). The private healthcare sector consistently showed the highest number of lawsuits when compared to other healthcare providers, with a 73% increase over 3 years. The Ministry of Health showed an overall reduction in the number of lawsuits by 6.6% over the course of the study period. CONCLUSIONS: The number of lawsuits in Saudi Arabia is increasing rapidly. Understanding the reason for this is very important especially given the high rates of lawsuits for certain specialties and healthcare sectors. A root cause analysis cannot be conducted without a detailed reporting system for malpractice lawsuits; the development of which would help in research and the generation of solutions in this field.

"Tele-urology": Is the COVID-19 pandemic a wake-up call?

BACKGROUND: The purpose of this research is to measure the current use of telemedicine technologies among urologists, their readiness to adopt the same, and to assess the barriers preventing such usage. METHODS: Two hundred and twenty eight board-certified urologists completed our self-designed survey. An analysis was done to assess the increase in the use of telemedicine and the urologists' telemedicine experience responses. Data analysis was done using SPSS software. RESULTS: There has been a tremendous increase in the use of telemedicine among urologists during the coronavirus disease (COVID-19) pandemic. Most of the respondents of this study performed general urology as part of their daily practice (59.6%). Prior to the pandemic, 53.9% of the participants had never used any means of telemedicine. However, during the pandemic, 72.4% of urologists who had never used telemedicine began using the same. Almost all of the respondents agreed that physical examination is difficult when using telemedicine, which resulted in the highest mean value among the questionnaire items. Urologists below 35-year-old agreed, to a larger extent, that telemedicine saves them more time and is simple to use than urologists from other age groups. CONCLUSION: During the COVID-19 pandemic, most urologists adopted telemedicine technology rapidly. Adopting telemedicine in the future could have multiple advantages. However, the limitations of telemedicine should be respected in order to avoid compromising patient safety.

Impact of COVID-19 pandemic on urology residency training.

CONTEXT: The COVID-19 pandemic has led a lot of countries worldwide to go on lockdown. Potential collateral damage is the impact of residency. AIMS: The aim of this study is to assess the impact of COVID-19 pandemic on urology training aspects, study habits of residents, and their awareness and training regarding COVID-19. SETTINGS AND DESIGN: A questionnaire aiming to assess the impact of COVID-19 pandemic on different urology training aspects. The questionnaire was sent to all urology residents under the Saudi Commission for Health Specialties (SCFHS) programs. SUBJECTS AND METHODS: Urology residents under SCFHS programs, excluding 1st-year residents. The questionnaire included the following sections: demographic data, studying habits during the pandemic, involvement in training before the pandemic, involvement in training during the pandemic, and training related to COVID-19. STATISTICAL ANALYSIS USED: Using the SPSS software, frequencies of all data were calculated, and a Wilcoxon-signed rank test was done to assess the change in ordinal data. RESULTS: A total of 77 residents completed the survey (38% response rate). Most residents (40.5%) reported that they "strongly agree" with the statement that they have more time for reading. There has been a decrease in on-call duties, outpatient visits, diagnostic procedures, endoscopic surgeries urology, minimally-invasive surgeries, and major open surgeries in comparison to before the pandemic, with a decrease in mean scores in all domains, especially in diagnostic procedures. CONCLUSIONS: There has been a decrease in residents' involvement in all training domains, and this has been similar to the results of other studies. E-learning sources, during these times, present themselves as a valuable source to compensate for what has been missed in training.

Survey of Saudi urology program directors: What do you look for in a candidate?

INTRODUCTION: Prospective urology applicants in Saudi Arabia must go through a rigorous matching process. Defining which aspects of an applicant's portfolio or interview will get them matched is difficult. Our objective is to provide information on which aspects of an application are the most important. SUBJECTS AND METHODS: In this cross-sectional study, an electronic survey was sent out to all urology program directors (PD). The survey included 27 items from an application that were rated by the respondent using a 5-point Likert scale. RESULTS: Twenty-three urology PD completed the survey (79.3% response rate). Most of the PD subspecialized in endourology and minimally invasive surgery. The three most important aspects as perceived by all responding PD were as follows: performance during rotation at the respondent's centre, publications in urology, and the total number of electives in urology. The three least important factors were as follows: presentations in fields other than urology, recommendation letters from nonurologists, and quality reference letters from nonurologists. CONCLUSION: Performance during rotations has been shown in our and other studies to be one of the most important factors in an application. Surveying PD on what they value the most in an applicant, provides valuable information and more transparency regarding the match processes. We also recommend that our colleagues from different specialties conduct similar studies.

Neural Network Analysis of Crystalluria Content to Predict Urinary Stone Type.

PURPOSE: To investigate the relationship between urinary stone type and the type of crystals in the urine. PATIENTS AND METHODS: This retrospective study involved 485 patients with urinary stones treated at King Saud University Medical City from May 2015 to June 2017. Clinical data were obtained from medical records. Different statistical analysis methods were applied, including basic contingency analysis, analysis of variance, logistic regression, discriminant analysis, partition modeling, and neural network evaluations. RESULTS: Of 485 patients, 47 had crystals detected by urinalysis. The most common type of crystal was calcium oxalate (n = 31), which had the highest association with calcium oxalate stones. Uric acid crystals (n = 8) were associated with uric acid stones. The neural network model used for determining the sensitivity and specificity showed an R-square value of 0.88, with an area under the curve of 0.94 for calcium oxalate, 0.94 for carbonate apatite, and 1.0 for uric acid. CONCLUSION: The predictive algorithm developed in the present study may be used with a patient's clinical parameters to predict the stone type. This approach predicts the stone types associated with certain patient characteristics with a high sensitivity and specificity, indicating that the models may be a valuable clinical tool in the diagnosis, management, and monitoring of stone diseases.

Pediatric urology surgical practice in the time of COVID-19: Results from tertiary Saudi Arabia hospitals.

PURPOSE: Our study aimed to evaluate the effect of COVID-19 on pediatric urology practice in the Kingdom of Saudi Arabia (KSA). METHODS: Data of 10 tertiary hospitals in KSA were retrospectively analyzed. Data of outpatient department (OPD) visits and pediatric urology surgical procedures from January 1, 2019, to April 30, 2019, and from January 1, 2020, to April 30, 2020, were extracted. The primary outcome was to compare OPD visits and pediatric urology workload in the first third of 2020 versus 2019, where there was no curfew. The secondary outcome was to compare the same variables during the full curfew time, i.e., April 2020 versus April 2019. RESULTS: The number of OPD visits was lower in the first third of 2020 (7390 vs. 10,379 in 2019 P < 0.001). OPD visits in April 2020 were 78.6% lower than in April 2019, and teleclinics represented 850 (94.3%). Elective procedures in the first third of 2020 were 688, with a reduction rate of 34.3% compared to the same period of 2019 (P < 0.001). In April 2020, there were 18 elective surgeries, with a 91.4% decrease than in April 2019. Ureteric reimplantation, hypospadias, cryptorchidism, and circumcision stopped, while pyeloplasty (n = 14) and urolithiasis (n = 4) procedures had declined by 50% and 76.5%, respectively. Most of the procedures (71.8%) were day surgery. Emergency procedures were similar in the first third of 2020 (65 vs. 64 in 2019, P = 0.994) and declined in April 2020 by 6.7% versus April 2019. During the full curfew, the most common emergency intervention were cases with obstructive uropathy (42.8%), followed by torsion testis (28.6%), posterior urethral valve (14.3%), and urological trauma (14.3%). CONCLUSIONS: In KSA, the number of elective pediatric surgical procedures were reduced by >90%, while the number of emergency pediatric surgical procdures were similar during COVID-19 pandemic compared with non-COVID-19 time. Ureteric reimplantation, hypospadias repair, cryptorchidism, and circumcision procedures were postponed. Pyeloplasty and urolithiasis-related procedures were performed to prevent irreversible disease progression or organ damage. There was an increase in rate of teleclinic and day surgery to reduce the risk of COVID-19 infection.
