Minimally invasive versus open pyeloplasty in pediatric population: Comparative retrospective study in tertiary centre.

Background: Ureteropelvic junction obstruction (UPJO) is the most common cause of antenatal hydronephrosis. The incidence is around 1: 750-1500 live births. The standard treatment for (UPJO) is open pyeloplasty (OP) with a high success rate of 90%-95%. In the last 20 years, minimal invasive pyeloplasty (MIP) became an excellent alternative technique to OP which was historically the standard of care. Materials and Methods: The study participants were male and female patients aged 14 years old or less who had undergone open/minimally invasive pyeloplasty during 2015-2020 and who had at least 1-year follow-up after surgery. The data were collected retrospectively from patients' charts. The patients were categorized into two cohort groups: OP and on the other arm minimally invasive pyeloplasty (robotic/laparoscopic) comparing the outcomes as a 1ry endpoint. 2ry endpoints were hospital stay, duration of surgery, and anteroposterior diameter of renal ultrasound. Results: A total of 133 patients were included in the study. Eighty-four underwent MIP while 49 patients underwent OP. 1ry endpoint was the success rate in both groups. The success rate was 94% (n: 79) and 98% (n: 48) in patients who underwent MIP and OP, respectively. P <0.05 is considered significant. Conclusion: Open and minimally invasive pyeloplasty are comparable in terms of success rate. However, OP was associated with shorter hospital stays and shorter operative times.

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.

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.

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.

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.

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.

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.

Exposure of Urology Residents to the Management of Urethral Strictures in Saudi Arabia: Should the Program for Postgraduates Be Customized?

PURPOSE: This study aimed to assess the exposure and knowledge of urology residents in the management of urethral stricture (US) and to determine if they would be able to perform urethroplasty after graduation and whether urethroplasty should be included as a competency in the training program. PATIENTS AND METHODS: An online survey was sent to all residents enrolled in any urology training program in Saudi Arabia. Fifty-eight (approximately 50%) of the 114 residents who were sent the survey provided responses. RESULTS: Most of the residents (45 residents, 77.6%) who responded were exposed to fewer than ten cases of US during their last year of training. Fifty-six residents (96.6%) attended five or fewer urethroplasty procedures in their last year of training. Twenty-three (40%) residents did not attend any urethroplasty procedure in the last year. The most common procedures attended by the residents were minimally invasive treatments (89% cystoscopy with dilatation and 79% direct visual internal urethrotomy (DVIU)). Most residents responded that they would manage newly diagnosed 1 cm US with either cystoscopy and dilatation or with DVIU 53 (91%). For the first recurrence of US, 46 (79%) residents responded that they would still prefer dilatation or DVIU. For the second, third, and chronic recurrences of US, 20 (34.5%), 6 (10.3%), and 5 (8.6%) residents, respectively, responded that they would perform dilatation or DVIU. Residents had low expectations for the success rate of urethroplasty; only 32 (55.2%) residents thought it had a high success rate. CONCLUSION: Urethroplasty is a specialized urological procedure, one that residents have variable exposure to. Privilege to perform such a procedure after graduating should be modified to ensure the best outcome for patients.

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.

Routine histopathological examination of the foreskin after circumcision for clinically suspected lichen sclerosus in children: Is it a waste of resources?

INTRODUCTION: Circumcision is one of the most widely performed procedures in the world. One of the indications for circumcision is lichen sclerosis (LS). The natural history of LS in children is not as well-documented as in adult patients. Surgeons use the appearance of the foreskin or meatus to predict the diagnosis of LS. Indeed, if the diagnosis of LS is made in childhood, does it change management in the long-term? Pathological analysis of the excised foreskin is routinely done if there is suspicion of LS. Our aim is to assess the concordance between the clinical and pathological diagnosis of suspected LS and to assess the need for sending the foreskin for pathological examination. METHODS: We conducted a retrospective chart review of 64 of 420 boys who underwent circumcision in a tertiary children's hospital from June 2005 to June 2014, and who had their foreskin sent for pathology due to the clinical suspicion of LS. Demographics, presenting symptoms, presumed clinical diagnosis, pathological findings, and followup data were collected and analyzed. RESULTS: Over the review period, 64 patients underwent circumcision for presumed LS. The mean age of the children was 9.7 years (range 3-16.5). All the children who had circumcision for presumed LS diagnosis were symptomatic. LS was confirmed in 47 of 64 foreskins (73.5%). Balanitis xerotica obliterans (BXO) was clinically suspected in 40 (85%) of the 47 patients. The mean followup was 10 months (range 1-15), with seven recurrences (15%) during that period. The recurrences required revision surgery in two patients and five were managed with steroids only. CONCLUSIONS: In our series, the clinical diagnosis correlated with the pathological diagnosis in most cases. A clinical suspicion of LS without routine foreskin pathological assessment will reduces the overall cost to the healthcare system. Appropriate counselling of the patient/parents and their primary caregiver is imperative, as recurrence is common.

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.

Single penile incision for combined hypospadias and inguinal surgery: A comparative study.

INTRODUCTION: We sought to compare the surgical outcomes of hypospadias repair with correction of inguinal pathology using a single penile incision vs. conventional approach using two incisions. METHODS: This is a retrospective study that reviewed all patients who underwent concurrent surgical repair for both hypospadias and inguinal pathologies between January 2003 and November 2015. Patients were classified into Group A, conventional (inguinal or scrotal and penile incision) approach; or Group B, single penile incision approach. Baseline characteristics, including age, degree of hypospadias, type and laterality of inguinal pathology, operative time, and surgical outcomes, were collected. Between groups, variable comparisons were analyzed using Mann-Whitney U-Test and Fisher-exact test. Statistical significant set at <0.05. RESULTS: Seventy-six patients (Group A: 40; Group B: 36) were eligible for study. Baseline characteristics of both groups were comparable, with no significant statistical difference. Overall mean operative time for Group A was 139.3 ± 56.2 minutes, while Group B was 107.8 ± 46.7 minutes (Z=2.6; U=470.5; p=0.009). Two patients in Group A and two patients in Group B had testicular ascension, all of which also had hypospadias-related complications (p=1.0). Hypospadias-related complications in Group A included seven urethrocutaneous fistulae and two repair dehiscence. Eight urethrocutaneous fistulae, one urethral stricture, and two repair dehiscence occurred in Group B (p=0.448). Surgical outcome appearance in both groups were comparable, with no statistically significant difference (p=0.466). CONCLUSIONS: Single penile incision for both hypospadias repair and correction of inguinal pathology is a feasible technique and comparable to the conventional approach, with similar surgical outcomes and shorter overall operative time.

Outcomes of seromuscular bladder augmentation versus standard ileocystoplasty: A single institution experience over 14 years.

INTRODUCTION: Ileocystoplasty is the standard technique used for bladder augmentation, and has been used widely for decades. However, it is known to be associated with complications such as stone formation, mucus production, metabolic acidosis, urinary tract infections, intestinal obstruction, and a long-term risk of bladder cancer. Seromuscular bladder augmentation (SMBA) is an alternative to the standard ileocystoplasty, and has been associated with a lower incidence of bladder stones. Few reports have been published on intermediate outcomes of SMBA. Herein, we report long-term outcomes of SMBA from a single institution compared with standard ileocystoplasty. METHODS: After Institutional Review Board approval, a retrospective chart review of all patients who underwent bladder augmentation at our institution over a 14-year period was performed. The status of patients after SMBA (10 patients) was compared according to age, sex, and diagnosis with patients who underwent traditional ileocystoplasty (30 patients). Parameters such as demographic information, pre- and postoperative bladder capacity as assessed by urodynamic studies, urinary tract infections (UTIs), bladder calculi, incontinence, need for secondary surgical procedures, and spontaneous bladder perforation were compared in the two groups. All the patients were on a clean intermittent catheterization (CIC) regimen. RESULTS: Over the study period, 10 patients underwent SMBA and 30 patients (according to age, sex, and diagnosis) underwent standard ileocystoplasty; the average age at surgery was 10.3 and 10 years respectively, with a mean follow up of 6.7 years in the SMBA group and 6 years in the ileocystoplasty group. There were no statistically significant differences in the rate of UTIs, urinary incontinence, subsequent surgery, or spontaneous bladder perforation. The mean bladder capacity increased significantly for both groups as assessed by pre- and postoperative urodynamic studies, although the difference in the rate of bladder calculi between the two groups (0 [0%] vs. 8 [27%], p = 0.06) did not reach statistical significance (Table). CONCLUSIONS: SMBA is safe and efficacious and may result in a lower rate of stone formation than standard ileocystoscopy. SMBA should be considered as a viable alternative to standard ileocystoplasty.

Utility and cost-effectiveness of uroflowmetry in a busy pediatric urology practice.

INTRODUCTION: Uroflowmetry (UF) is frequently employed in daily pediatric urology practice for diagnostic and follow-up purposes. We assess the utility and cost-effectiveness of UF in the management of patients seen at a tertiary care centre. METHODS: We retrospectively reviewed the charts of consecutive patients who had a UF between January 1, 2010 and March 31, 2010. We collected data on demographics, diagnosis, UF parameters and the impact of the UF on management. The impact on management was defined as indication for surgery, introduction of new medications and bladder retraining based on clinical and UF findings. RESULTS: In total, 524 patients were included in the study. In 63 (12%) patients, UF was performed as part of the evaluation at the first clinic appointment. The most common diagnoses were voiding dysfunction (VD) 41%, hypospadias 26%, vesicoureteric reflux (VUR) 16%, monosymptomatic nocturnal enuresis (NE) 8%, posterior urethral valves 5% and meatal stenosis (MS) 4%. In the VD group, UF contributed to a management decision in 25.2% of patients. In the MS group, surgical intervention was based on symptoms and supported by the UF in 41% of patients; in the PUV group, 50% of patients demonstrated high (>20 cc) post-void residual, which aided in management decisions. In contrast, there were virtually no changes in management supported by the UF in the NE, VUR and hypospadias groups. Overall, UF parameters had a direct influence in the management decisions in only 67 (12.8%) patients. Nonetheless, a repeat test was ordered for 44.5% of patients. CONCLUSIONS: In an era of financial restraints and in a busy tertiary pediatric urology practice, judicious use of UF for specific indications may translate into a more cost-effective use of time and resources. As expected, patients with VD were the ones that benefited most from the test, as did patients with symptomatic MS and PUV.

Metastatic renal cell carcinoma to the testis: A case report and review of the literature.

This is a case of a 68-year-old male who presented with a chief compliant of a testicular mass, which was discovered to be a meta-static lesion of undiagnosed renal cell carcinoma. A computed tomography scan revealed a large right renal mass and multiple pulmonary metastasis. Shortly after diagnosis, the patient was initiated on systemic therapy and received a cytoreductive nephrectomy. We discuss the details of this case as well as a pertinent review of metastatic renal cell carcinoma to the testes.

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.

Laparoscopic partial nephrectomy for >4 cm renal masses.

INTRODUCTION: Laparoscopic partial nephrectomy (LPN) is frequently used to manage cT1a renal masses. While data on safety and long-term oncological outcomes of LPN for T1a tumours are widely available, it is limited for >T1a lesions. We report our experience with LPN for >4 cm renal masses from a Canadian tertiary centre. METHODS: Between January 2003 and July 2011, 52 consecutive LPN for >4 cm renal masses were performed. Demographic, pathological and clinical data were obtained from a prospectively maintained database. RESULTS: The mean patient age was 60 years (62% male). Median tumour size was 4.8 (range: 4.2-11) cm. The median surgical time was 145 minutes, and the median estimated blood loss was 100 mL. The median warm ischemia time was 24 minutes. Four (7.7%) cases required conversion to open surgery. One case was converted to total nephrectomy for clinical and pathological evidence of T3 disease. The surgical margin was positive in 1 case (1.9%). Four (7.7%) patients developed a urine leak postoperatively; 3 of them managed with a ureteric stent. Four (7.7%) patients developed postoperative bleeding requiring selective angioembolization. The median hospital stay was 4 days. There was no statistically significant difference between preoperative and postoperative estimated glomerular filtration rate and mean arterial blood pressure (p = 0.5, p = 0.1, respectively). CONCLUSION: This series demonstrates that LPN although technically challenging has acceptable short-term surgical outcomes. Long-term assessment of oncological outcomes is required. Laparoscopic partial nephrectomy >4 cm renal tumours should not be considered a standard of care, but excellent results can be achieved in well-selected patients and in experienced hands with no impact in renal function or blood pressure.

Is an overnight stay after percutaneous nephrolithotomy safe?

OBJECTIVES: To establish a clinical care pathway that plans for hospital discharge the day after percutaneous nephrolithotomy (PCNL), to evaluate the safety, effectiveness and feasibility of this pathway, and to identify factors associated with a postoperative length of hospital stay (LOS) of >1 day. PCNL is the treatment of choice for patients with large kidney stones and those in whom extracorporeal shockwave lithotripsy has failed, and the mean LOS is typically 2-5 days. PATIENTS AND METHODS: We retrospectively reviewed the charts of 109 patients (mean age 57.4 years; 58 men, 53%) who had PCNL between 2006 and 2009. All had nephrostomy tubes placed after surgery. The patients' demographics, LOS, incidence of complications, clinical outcomes, stone-free rates, number of early postoperative emergency-room visits, need for subsequent admission and/or other procedures, were noted and analysed. The modified Clavien classification was used to describe the postoperative complications. Bivariate analyses were used to test for associations between LOS and other variables. RESULTS: The mean (range) stone size was 2.2 (0.9-5.9) cm, and the mean (SEM) LOS was 1.7 (0.13) days. Of the 109 patients, 20% had a LOS of >1 day for surgical, 3% for medical and 5% for social reasons. The stone-free rate was 89%. There was no difference in the number of subsequent hospital visits or ancillary procedures for patients discharged after one or more postoperative nights. No variables were associated with a longer LOS. CONCLUSIONS: An overnight hospital stay after PCNL is safe and represents an effective strategy for improved bed use in selected patients. A longer LOS was not affected by patient age or body mass index, stone size or operative time. We continue to use our clinical care pathway, as supported by these data.
