Comparison of scrotal and inguinal orchiopexy for palpable undescended testis: a meta-analysis of randomized controlled trials

INTRODUCTION

Scrotal and inguinal orchiopexy are two commonly used surgical approaches for palpable undescended testis (UDT), each with distinct advantages. However, the optimal approach remains a matter of debate, warranting a comprehensive meta-analysis of randomized controlled trials (RCTs) to guide clinical decision-making.

MATERIALS AND METHODS

A comprehensive literature search was conducted, adhering to PRISMA guidelines, to select RCTs comparing scrotal and inguinal orchiopexy for palpable UDT. Eight RCTs were selected for meta-analysis. Outcome measures included operative time, hospitalization duration, total complications, wound infection or dehiscence, testicular atrophy or hypotrophy, and testicular re-ascent rate. The evaluation of the study's quality was conducted by utilizing the revised Cochrane risk-of-bias tool.

RESULTS

Scrotal orchiopexy showed significantly shorter operative time compared to the inguinal approach (WMD: - 15.06 min; 95% CI: - 21.04 to - 9.08). However, there was no significant difference in hospitalization duration (WMD: - 0.72 days; 95% CI: - 1.89-0.45), total complications (OR: 1.08; 95% CI: 0.70-1.66), wound infection or dehiscence (OR: 0.73; 95% CI: 0.27-1.99), testicular atrophy or hypotrophy (OR: 1.03; 95% CI: 0.38-2.78), and testicular re-ascent (OR: 1.43; 95% CI: 0.67-3.06) between the two approaches. A small proportion of cases (7.3%) required conversion from scrotal to inguinal orchiopexy due to specific anatomical challenges.

CONCLUSION

Both scrotal and inguinal orchiopexy are safe and effective for palpable UDT, with comparable outcomes in terms of hospitalization and complications. Scrotal orchiopexy offers the advantage of shorter operative time. Clinicians can use this evidence to make informed decisions on the surgical approach for palpable UDT.

A Retrospective Analysis of the 1-Year Graft Survival Rate in Indonesian Renal Transplant Recipients With Multiple Renal Arteries

BACKGROUND

Renal transplantation is the preferred treatment for end-stage renal disease because of its association with improved survival and quality of life. The debate over multiple renal arteries (MRA) vs a single renal artery regarding kidney function, posttransplant complications, and graft and patient survival remains ongoing. Our goal was to determine the 1-year graft survival rate among renal transplant recipients with MRA at Cipto Mangunkusumo Hospital in Jakarta.

METHODS

A retrospective study was conducted between January 2012 and December 2020, including all kidney transplant candidates with MRA. Data on graft survival, patient demographics, previous renal transplantation, duration of hemodialysis, and delayed graft function were collected and analyzed using SPSS 24. Kaplan-Meier plots and Cox regression analyses were used to determine risk factors for 1-year survival.

RESULTS

Among 752 renal transplant recipients, 104 cases had MRA. The majority were men (71.5%), and the median age of recipients was 47 years. One-year graft survival was observed in 96% of cases, whereas patient survival was 97.7%. No significant difference was found in graft survival based on the number of arteries (single renal artery vs MRA), length of hemodialysis, or previous renal transplantation. However, delayed graft function was significantly associated with graft survival.

CONCLUSION

This study highlights that 1-year graft survival in renal transplant recipients with MRA is not significantly affected by the length of hemodialysis before surgery or previous renal transplantation.

Method for determining predictor factor for worse outcomes in kidney transplant recipients infected with coronavirus disease 2019 in a systematic review and meta-analysis research

The systematic review and meta-analysis were conducted for COVID-19 infections in kidney transplant patients. Recent research on this topic was still scarce and limited meta-analysis research discussion, specific to some risks or treatment in kidney transplantation patients with COVID-19 infection. Therefore, this article demonstrated the fundamental steps to conducting systematic review and meta-analysis studies to derive a pooled estimate of predictor factors of worse outcomes in kidney transplant patients with positive for the SARS-CoV- 2 test•PICOT Framework to determine the research scope•PRISMA strategy for study selection•Forest Plot for meta-analysis study.

Associations of ureteroceles location and system anatomy with outcomes of endoscopic treatment: A systematic review and meta-analysis

INTRODUCTION

Ureteroceles are a congenital abnormality of the ureter that can cause significant complications. Endoscopic treatment is a commonly used treatment approach. The aim of this review is to assess the results of endoscopic treatment for ureteroceles with consideration to their location and system anatomy.

METHODS

A meta-analysis was conducted by searching electronic databases for studies comparing outcomes of endoscopic treatment for ureteroceles. Newcastle-Ottawa Scale (NOS) was employed to evaluate the potential for bias. The primary outcome was the rate of secondary procedures required following endoscopic treatment. Secondary outcomes were inadequate drainage and post-operative vesicoureteral reflux (VUR) rates. A subgroup analysis was performed to investigate possible causes of heterogeneity in the primary outcome. The statistical analysis was conducted using Review Manager 5.4.

RESULTS

There were 28 retrospective observational studies, published between 1993 and 2022, including 1044 patients with primary outcomes in this meta-analysis. The quantitative synthesis showed that ectopic and duplex system ureteroceles were significantly associated with higher rate of secondary operation compared to intravesical and single system ureteroceles, respectively (OR: 5.42, 95% CI: 3.93-7.47; and OR: 5.10, 95% CI: 3.31-7.87). The associations were still significant in subgroup analysis based on follow up duration, average age at surgery, and duplex system only. For secondary outcomes, incidence of inadequate drainage were significantly higher in ectopic (OR: 2,01, 95% CI: 1.18-3.43), but not in duplex system ureteroceles (OR: 1.94, 95% CI: 0,97-3.86). Post-operative VUR rates were higher in both ectopic (OR: 1.79, 95% CI: 1.29-2.47) and duplex system ureteroceles group (OR: 1.88, 95% CI: 1.15-3.08).

CONCLUSION

Ectopic ureteroceles and duplex system ureteroceles were associated with worse outcomes following endoscopic treatment compared to intravesical and single system ureteroceles, respectively. It is recommended to carefully select patients, conduct pre-operative evaluations, and closely monitor patients with ectopic and duplex system ureteroceles.

Bilateral single system ectopic ureters with bilateral urethral insertion and horseshoes kidneys in a female child

A 14-months old female child was diagnosed with bilateral single system ectopic ureters opening into the urethra, with small bladder capacity, horseshoes kidneys, and bilateral hydronephrosis, presenting recurrent febrile UTI accompanied by continuous incontinence and elevated renal function. Early bilateral re-implantation of the ureters (modified Lich-Gregoir) was done in one setting, resulting jn no recurring febrile UTIs and continuous wetting, improving renal function parameter, competent bladder neck, and 10 folds increased in bladder capacity after 1-year follow up. We showed that earlier treatment enables patient to preserve both renal and bladder function without involving complex reconstructive surgery.

Association Between De Novo C1q-Binding Donor-Specific Anti-HLA Antibodies and Clinical Outcomes After Kidney Transplantation: A Meta-Analysis

BACKGROUND

Donor-specific antibodies (DSAs) are recognized as an important factor of kidney allograft loss as a subsequent event of antibody-mediated rejection (AMR). The clinical relevance of de novo DSAs (dnDSAs) after kidney transplant, particularly in their ability to bind C1q, has been widely investigated to various extents among studies. A recent study was performed to examine the association between C1q-binding dnDSAs and succeeding clinical events after kidney transplant.

METHODS

A meta-analysis of studies published before April 2021 was conducted from PubMed, Science Direct, and Cochrane databases. Publications on dnDSA after kidney transplant focusing on differentiation between C1q-binding and non-C1q-binding were included. The outcomes analyzed were AMR rate and allograft loss. Studies using preformed DSA were excluded. The pooled risk ratio and 95% confidence interval (CI) were analyzed using Mantzel-Haenzel method, and the I2 value was used to determine the heterogeneity of the studies. Data analysis was conducted using Review Manager 5.3.

RESULTS

A total of 535 patients from 13 studies who developed dnDSA after kidney transplant were analyzed. Among these, 239 (44.7%) had C1q-binding and 296 (55.3%) had non-C1q-binding dnDSA. Acute AMR was found in 59.2% (97/164) of the C1q-binding group and in 28.8% (49/170) of the non-C1q-binding group (risk ratio [RR], 0.58 [95% CI, 0.39-0.85], P = .006, I2 = 58%). Chronic AMR was found in 50% (19/38) of the C1q-binding group and in 16.9% (11/65) of the non-C1q-binding group (RR, 0.39 [95% CI, 0.21-0.71], P = .002, I2 = 0%). Allograft loss was found in 62.2% (74/119) of the C1q-binding group and in 34.1% (60/176) of the non-C1q-binding group (RR, 0.57 [95% CI, 0.38-0.85], P = .006, I2 = 61%).

CONCLUSIONS

This meta-analysis demonstrates that patients who developed C1q-binding dnDSA display an increased risk of AMR and allograft loss compared with those with non-C1q-binding dnDSA. Therefore, C1q-binding dnDSAs are associated with inferior outcomes after kidney transplant.

Circumcision reduces urinary tract infection in children with antenatal hydronephrosis: Systematic review and meta-analysis

INTRODUCTION

Urinary tract infection (UTI) is more prevalent in boys with antenatal hydronephrosis (ANH). Circumcision is known to lessen the risk of UTI. This study was performed to examine the associations between circumcision and UTI among patients with ANH.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards were followed for conducting this systematic review and meta-analysis. PubMed, ScienceDirect, EMBASE, and Cochrane Library databases were searched through August 4th, 2022 to identify eligible studies. The risk of bias was measured using the Newcastle-Ottawa Scale (NOS). Review manager 5.4 was used for all analysis.

RESULTS

A total of 21 studies involving 8,968 patients with ANH were included in the meta-analysis. The incidences of UTI were 18.1% in the uncircumcised group and 4.9% in the circumcised group. From analysis, circumcision had significant protective effect against UTI with pooled OR of 0.28 (95% CI 0.23-0.32). The significant protective effects were also found in subgroup analysis of hydronephrosis etiology, including vesicoureteral reflux (pooled OR of 0.24; 95% CI 0.17-0.32), obstructive hydronephrosis (pooled OR of 0.34; 95% CI 0.21-0.53), and posterior urethral valve (pooled OR of 0.28; 95% CI 0.16-0.52).

CONCLUSION

Our meta-analysis showed that circumcision was associated with a decreased incidence of UTI in children with ANH. This benefit was consistent irrespective of the underlying cause of hydronephrosis.

Predictor factor for worse outcomes in kidney transplant recipients infected with coronavirus disease 2019: A systematic review and meta-analysis

INTRODUCTION

The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a massive impact on the health sector, especially in patients with pre-existing comorbidities. This study aims to define the predictor factors for worse outcomes in kidney transplant patients infected with SARS-CoV-2 and affected by coronavirus disease 2019 (COVID-19). We have analyzed in these patients their prior medical history, their clinical symptoms, and their laboratory results.

METHOD

We assessed outcomes of kidney transplant patients with confirmed COVID-19 until July 2021 from PubMed, Medline, Science Direct, Cochrane databases, EMBASE, Scopus, and EBSCO. We performed meta-analyses of nine published studies to estimate predictor factors. The analysis was analyzed by the Newcastle-Ottawa Scale (NOS) and then using the Review Manager 5.4 software.

RESULT

Our analysis demonstrated that the most significant risk factors for the worse COVID-19 outcomes for kidney transplant patients included: age of 60 and older [MD 9.31(95% CI, 6.31-12.30), p < 0.0001, I2 = 76%], diabetic nephropathy [OR 2.13 (95% CI, 1.49-3.04), p < 0.0001, I2 = 76%], dyspnea [OR 4.53, (95% CI, 2.22-9.22), p < 0.0001, I2 = 76%], acute kidney injury (AKI) [OR 4.53 (95% CI, 1.10-5.21), p = 0.03, I2 = 58%], and some laboratory markers. Many patients had two or multiple risk factors in combination.

CONCLUSION

Age and several comorbidities were the most significant factors for COVID-19 outcomes for kidney transplant recipients.

COMPARISON OF ANDROGEN AND ESTROGEN RECEPTORS’ EXPRESSION IN DARTOS TISSUE OF BOYS WITH AND WITHOUT HYPOSPADIAS

Objective: This study aims to investigate the characteristics of androgen receptors (AR), estrogen receptor 1 (ER1) and estrogen receptor 2 (ER2) expression in dartos tissue of patients with congenital hypospadias, compared to normal penis. Material & Methods: We harvested 63 dartos tissue consisting of 53 congenital hypospadias that underwent urethroplasty (20 distal and 33 proximal) and 10 normal penis that underwent circumcision as controls from September 2017 to September 2018. The expressions of AR, ER1, and ER2 were measured using Quantitative Real-Time PCR (qPCR). All data were analyzed by Prism 7, and one-way ANOVA tests were used to compare gene expressions between the groups. Results: The mean age was 68.99 (± 45.5) and 65.6 (± 25.8) months in boys with and without hypospadias, respectively. The expression of mRNA AR was decreased in proximal (6.26 ± 2.30) and distal hypospadias (6.43 ± 2.22) compared to controls (9.69 ± 1.10), which were statistically significant (p=0.0001 and p<0.0001, respectively). We found a statistically significant difference of ER1 expression compared to controls (p=0.0064). The expression of ER2 was significantly increased in distal (21.03 ± 5.00) and proximal hypospadias (25.21 ± 8.06) groups compared to controls (11.80 ± 2.49) (p<0.0001). There was no statistically significant mean difference in mRNA ER1 expression (p=0.65). Conclusion: The repressed AR and elevated ER mRNA as shown in our study may suggest that defects in those receptors’ interaction and/or balance may contribute to hypospadias and penile curvature condition. Further studies are needed to evaluate any gene-related problems in hypospadias. Keywords: Hypospadias, androgen receptor, estrogen receptor, dartos tissue.  

Digital Pattern Recognition for the Identification of Various Hypospadias Parameters via an Artificial Neural Network: Protocol for the Development and Validation of a System and Mobile App

BACKGROUND

Hypospadias remains the most prevalent congenital abnormality in boys worldwide. However, the limited infrastructure and number of pediatric urologists capable of diagnosing and managing the condition hinder the management of hypospadias in Indonesia. The use of artificial intelligence and image recognition is thought to be beneficial in improving the management of hypospadias cases in Indonesia.

OBJECTIVE

We aim to develop and validate a digital pattern recognition system and a mobile app based on an artificial neural network to determine various parameters of hypospadias.

METHODS

Hypospadias and normal penis images from an age-matched database will be used to train the artificial neural network. Images of 3 aspects of the penis (ventral, dorsal, and lateral aspects, which include the glans, shaft, and scrotum) will be taken from each participant. The images will be labeled with the following hypospadias parameters: hypospadias status, meatal location, meatal shape, the quality of the urethral plate, glans diameter, and glans shape. The data will be uploaded to train the image recognition model. Intrarater and interrater analyses will be performed, using the test images provided to the algorithm.

RESULTS

Our study is at the protocol development stage. A preliminary study regarding the system's development and feasibility will start in December 2022. The results of our study are expected to be available by the end of 2023.

CONCLUSIONS

A digital pattern recognition system using an artificial neural network will be developed and designed to improve the diagnosis and management of patients with hypospadias, especially those residing in regions with limited infrastructure and health personnel.

Rare cases of vesicouterine fistula

CASE

Vesicouterine fistula (VUF) is the rarest form of genitourinary fistulas. As lower-segment cesarean section becomes a more common mode of delivery, they have become the leading cause of VUF formation. We present four VUF patients with varied symptoms such as menouria, amenorrhea, with or without urinary incontinence. We diagnosed all of our cases through cystoscopy in conjunction with methylene blue dye test or hysteroscopy.

OUTCOME

We successfully repaired VUF in three open surgery instances and one laparoscopic case. To diagnose VUF, cystoscopy and hysteroscopy are still the gold standard. An expert surgeon's open or laparoscopic repair is effective and safe. The patients no longer experienced incontinence, cyclical hematuria (menouria), discomfort, or sexual dysfunction.

CONCLUSION

Cystoscopy and hysteroscopy remain the gold standard tool in diagnosing VUF. Open or laparoscopic repair performed by an experienced surgeon is an effective and safe technique with a successful outcome.

Delivery in a Female Bladder Exstrophy Patient With Ileal W Pouch Continent Cutaneous Stoma

Propose: To deliver a case report of female bladder exstrophy patients who experienced pregnancy until the birth process. Methods: A 28-year-old woman with a history of bladder exstrophy, which received inadequate treatment during childhood, had bladder shrinkage and uterine prolapse. The patient underwent reconstruction of continent cutaneous stoma and sacrocolpopexy with mesh in her adulthood. She achieved complete continence by intermittent self-catheterization and gained a better quality of life. She later got married and became pregnant. Pregnancy monitoring was done to evaluate the condition of the patient and her fetus. A collaborative team was built to discuss the best option for delivering the procedure. At 38–39 weeks of gestational age, an elective cesarian section was performed to deliver the baby. Results: Despite having a greater risk of complications, a woman with a history of bladder exstrophy could undergo pregnancy and give birth. The choice of delivery, either vaginal or cesarean section, is feasible for delivery. Conclusions: An adult female with bladder exstrophy underwent pregnancy and gave birth. Prior surgery and increased risk of obstetrical complications must be considered.

Factors related to the success rate of pediatric extracorporeal shock wave lithotripsy (ESWL) in Cipto Mangunkusumo Hospital: an 8-year single-center experience

Background

ESWL is still considered as the first favorable therapeutic option for urinary stone disease with acceptable effectivity. However, factors associated with favorable outcome have not been widely studied in pediatrics due to the small number of urinary stone prevalence. The aim of this study is to evaluate the factors associated with the success rate of pediatric ESWL in our center according to immediate stone-free rate and 3-month stone-free rates.

Methods

This is a retrospective cohort study of children less than 18 years who had ESWL for urolithiasis from January 2008 until August 2015. Patient’s characteristics including age, gender, BMI, stone location, stone length, stone burden, stone opacity, and number of ESWL sessions were gathered from the medical record. Nutritional status was determined according to the Centers for Disease Control and Prevention BMI curve. The outcome of this study was the factors related to the success rate in pediatric ESWL.

Results

Extracorporeal shock wave lithotripsy was done for 36 patients and 39 renal units (RUs) with mean age of 13.7 ± 4.3 years old, height of 1480 ± 16.0 cm, and BMI of 20.0 ± 3. Of 36 patients included, 39 renoureteral units (RUs) and 46 ESWL sessions were recorded. The mean overall treatment was 1.2 ± 0.5 sessions with mean stone length of 11.1 ± 6.3 mm and stone burden of 116.6 ± 130.3 mm2. Within 3 months of follow-up, we recorded that the overall 3-month success rate was 100%, while the overall 3-month stone-free rate was 66.7%. Stone length (p < 0.001 and p < 0.001), stone perpendicular length (p < 0.001 and p < 0.001), and stone burden (p < 0.001 and p = 0.001) were found to be significantly associated with immediate success and 3-month stone-free status, respectively.

Conclusions

ESWL is an effective and safe modality to treat pediatric urolithiasis cases. Stone length, stone perpendicular length, and stone burden were found to be associated with immediate success and 3-month stone-free status after pediatric ESWL treatment.

Minimal Invasive Treatment in Pelvic-Ureteric Junction Obstruction: A Comprehensive Review

Pelvic-ureteric junction obstruction (PUJO) is a common condition, and one of the lead causes of hydronephrosis in children. Currently, the gold standard treatment of PUJO is open surgery using the Anderson–Hynes-modified dismembered pyeloplasty technique. However, with the advancement of medical technology, several minimal invasive approaches were developed, including endoscopic, laparoscopic, and robotic approach, from which the best choice of surgical technique was yet to be determined. Considering the advantages and disadvantages of these methods, the recommended option is to tailor the best surgical approach to each individual patient, and to the surgeons’ preference and experience. Considering these recent advances, a new algorithm is proposed to choose the best minimal invasive modalities invasive treatment to treat PUJO.

Precocious Pseudo-Puberty with Testicular Enlargement: Two Cases of Leydig Cell Tumor with Different Histopathological Results

Introduction

Leydig cell tumors (LCT) are the most common hormone-secreting testicular tumors; it is a rare cause for precocious pseudo-puberty in boys. The tumors secrete high amounts of testosterone. We present two cases of LCT in prepubertal boys presenting with precocious puberty.

Case Reports

Case 1. A 6-year-old boy was referred from the pediatric department with a diagnosis of precocious puberty. The patient had reported enlarged and painless swelling of the left testicle from a year ago. The puberty status of the patient was A1P3G4. Ultrasonography examination had found left testicular mass. Elective radical orchiectomy of the left testicle was performed. Histopathological analysis confirmed the diagnosis of benign LCT. Case 2. A 6-year-old boy presented with an enlarged left testicle for the last three months. Features of puberty were noted on the patient (appearance of pubic and facial hair). The puberty status of the patient was A1P3G3. Left testicle US had found homogenous, hypoechoic mass with calcification. Bone age had found increased bone maturation. Increased androgen hormones were detected through a blood test. Radical orchiectomy of the left testicle was performed. The histopathological examination showed malignant LCT.

Conclusion

Leydig cell tumors uncommonly occur in children. Prepubertal-aged boys presented with asymmetrical, firm, painless testicular enlargement with signs of puberty should be evaluated for LCT. Histopathological analysis is the mainstay of diagnosis and radical orchiectomy is the treatment of choice of LCT.

Experience of the first 6 years of pediatric kidney transplantation in Indonesia: A multicenter retrospective study

BACKGROUND

Pediatric kidney transplantation was only introduced in Indonesia in 2013. We therefore aimed to assess the characteristics and outcomes of transplants performed from its inception to January 2019.

METHOD

The study had a dual-center retrospective design. We examined the records of kidney transplant recipients and then calculated patient and graft survival rates by Kaplan-Meier survival analysis with 95% confidence intervals (95% CI).

RESULTS

In total, 12 kidney transplantations were performed in eleven children during the study period; among these, ten were boys, and nine had renal failure caused by congenital anomaly of the kidney or urinary tract. All donors were living, and all recipients were on dialysis at the time of transplantation, when their median age was 14.5 years (range, 8-19 years). Three patients died of infection in the first year of follow-up and two lost their allograft by the time of their last follow-up (median, 13 months; range, 4-69 months). The 1-year patient survival rate was therefore 68.18% (95% CI, 29.72%-88.61%), which remained unchanged at 3 and 5 years. However, the non-death-censored graft survival rates at 1, 3, and 5 years were 68.18% (95% CI, 29.72%-88.61%), 51.14% (95% CI, 14.5%-79.46%), and 25.57% (95% CI, 1.38%-64.78%), respectively.

CONCLUSION

Patient and graft survival rates after pediatric kidney transplantation in Indonesia are lower than those reported in other countries. Closer patient follow-up and stricter adherence to guidelines could improve transplant outcomes, but we must seek to improve the balance between infection and rejection.

Genital reconstruction in an adult female patient with idiopathic clitoromegaly: A case report

INTRODUCTION

Clitoromegaly is an abnormality condition commonly related to congenital adrenal hyperplasia; it is rare due to idiopathic. Until now, there is no report about idiopathic clitoromegaly who reach adulthood and evaluation of their sexual life after reconstructive surgery.

PRESENTATION OF CASE

We presented an adult female patient with chief complain of enlarged clitoris since birth. The phenotypic appearance of ambiguous external genitalia resembling severe hypospadias with scrotal bifid. Other female secondary sexual characteristics were normal. The karyotype test result was 46 XX. We did genitalia reconstruction with nerve-sparing clitoroplasty, oral mucosal graft vaginoplasty, and labioplasty.

DISCUSSION

Many factors contribute to clitoromegaly which emerge transiently during the intrauterine period. Our case was unique due to clitoromegaly persistence until adulthood and can not be explained by any hypotheses. Adult females with clitoromegaly and urogenital sinus (UGS) bring a specific problem, especially to their sexual life. The reconstructive surgery should consider the phenotype of genital anatomy, preservation of clitoral neurovascular bundles, and adequate dimension of the vagina. Oral mucosal graft is an option as substitutive materials that can be used for vaginal augmentation.

CONCLUSION

This is a case report of adult female idiopathic clitoromegaly patient. Scrutinized evaluation is needed to confirm the diagnosis. Many aspects should be considered to perform feminizing genitoplasty. The surgery did not reduce the sensitivity of clitoris and allow the patient to do sexual activity after marriage during a one-year follow up.

Kidney transplantation with vesicostomy in small-bladder capacity neurogenic bladder dysfunction patient: A case report

Spinal cord injury often results in neurogenic bladder condition and eventually lead to an end-stage renal disease requiring kidney transplantation. However, transplantation in abnormal bladder carries special considerations. We report a case of an adult male with end-stage chronic kidney disease and small bladder capacity after having spinal cord injury. The evaluation of videourodynamic showed reduced compliance and detrusor overactivity during filling phase. Kidney transplantation and vesicostomy was performed. Eighteen months follow-up after surgery showed that kidney function could be maintained. The prevention of increasing bladder pressure and UTI should be monitored to prevent the damage of the graft kidney.

Comparison of Outcome and Success Rate of Onlay Island Flap and Dorsal Inlay Graft in Hypospadias Reconstruction: A Prospective Study

Background

Chordee correction, urethroplasty, and tissue reconstruction are performed to correct and retain standard functionality of the penis in hypospadias. Conventional reconstruction techniques, such as onlay island flap and the dorsal inlay graft, can be performed based on the classification of hypospadias. However, the outcomes and complication rates have not been widely studied. Thus, we aimed to provide preliminary evidence regarding the efficacy and safety of both approaches in hypospadias reconstruction.

Patients and Methods

A prospective study with two time evaluations of 14 and 180 days post-operatively was performed at the Urology outpatient clinic from October 2014 to September 2019. A proportion comparison of success rate, time to the complication, operation time, catheterization duration, uroflowmetry parameter post-surgery, and mean scores comparison of PPPS were measured as the intended outcomes.

Results

In a total of 59 pediatric hypospadias, patients who had undergone reconstruction are included in this study. Higher subjects’ age and severe chordee severity were more common in the dorsal inlay graft group (age=7.50 [1–26] months; severe chordee 45.8%) compared to the onlay island flap group (age=4.0 [1–67] months; severe chordee 31.4%), both groups showed similar satisfaction regarding meatal shape and position (P=0.618), glands shape (P=0.324), penile skin shape (P=0.489), and general cosmetic appearance (P=0.526). Complication occurrence and time to complication duration of both groups were also not statistically significant (P=0.464 and P=0.413). There are no significant differences in Q_max, Q_mean, voided volume, and PVR of both groups (P=0.125, 0.136, 0.076, 0.260, respectively). Significant differences in operation times and catheterization duration are found in this study (P<0001).

Conclusion

Outcome evaluation regarding functional, complication and patient satisfaction comparing onlay flap and dorsal inlay graft for hypospadias patients is scarce. This study found that both procedures can be considered safe with comparable incidence of complications.

Bilateral ureteral triplication: A case report

Ureteral triplication is among the rarest congenital disorder of the urinary tract. A review of the literature has shown that only about one hundred cases have been reported worldwide. The reports on bilateral ureteral triplication cases, however, are extremely scarce. A female infant was presented with a history of recurrent febrile UTI since birth. Computed tomography urography scan revealed bilateral ureteral triplication. Combination of contrast studies and endoscopic procedure were utilized to establish the diagnosis. Management for this anomaly varies from conservative to interventional surgery. This patient underwent laparoscopic left ureteroneocystostomy and ureteral tailoring.

Expression of mRNA Mastermind-like Domain-containing 1, Androgen Receptor, and Estrogen Receptor in Patients with Hypospadias

BACKGROUND: Androgen (AR) and Estrogen (ER) hormones play an important role in the prenatal and postnatal development of the urogenital tract and especially the penis. Growth factors also influence the development of genital structures. Little is known about the exact role of Mastermind Like Domain 1 (MAMLD1) in sexual development. A role in sex differentiation through supporting testosterone production in critical periods of male development has been suggested. MAMLD1 mutations result in hypospadias with and without a disorder of sexual development (DSD) primarily because of compromised testosterone production around the critical period for fetal sex development, but the underlying etiology remains unclear. AIM: The objective of this study was to investigate the correlation between gene factor MAMLD1, AR, ER1, and ER2 with the incidence of hypospadias. OBJECTIVE: The objective of this study was to investigate the correlation between gene factor MAMLD1, AR, ER1, and ER2 with the incidence of hypospadias. METHODS: From 2017-2018, peri-urethral dartos were harvested from 46 patients with proximal hypospadias, 24 patients with distal hypospadias and 10 patients with normal penile were used as controls. The expressions of MAMLD1, AR, ER1, and ER2 were investigated by one-step quantitative polymerase chain reaction. RESULTS: Median age was 5 years old in the 70 patients with hypospadias and 6 years old in the control subjects. Total specimens taken included 24 distal penile, 46 proximal penile, and 10 normal penile specimens. We found decreasing MAMLD1 and AR expressions, but ER2 expression increased in patients with hypospadias compared to controls, which was statistically significant (p < 0.001). A positive correlation between MAMLD1 and AR was found in patients with hypospadias (r = 0.062; p = 0.038). CONCLUSIONS: Decreasing of MAMLD1 and AR expression was followed by increasing ER2 expression in patients with hypospadias. MAMLD1 had a positive correlation with AR so the defect of MAMLD1 may influence AR and increase the incidence of hypospadias.

Single-stage urethroplasty: An eight-year single-centre experience and its associated factors for urethrocutaneous fistula

Introduction:

This study aimed to describe single-stage urethroplasty and to determine factors associated with urethrocutaneous fistula after the procedure at our institution.

Methods:

All hypospadias patients without any prior surgery who underwent single-stage urethroplasty from July 2010 to January 2018 were included. In total, 179 patients were followed for at least one year postoperatively. Information on types of hypospadias, operation techniques, chordee degree, preoperative pyuria (urine white blood cell count >5/HPF), urethral defect length and urethrocutaneous fistula formation was collected.

Results:

We obtained 103 cases of posterior (57.5%), middle (57 cases) and anterior (19 cases) hypospadias on whom onlay preputial island flap (71 cases), tubularized incised plate (46 cases) and Duckett’s transverse preputial island flap (35 cases) were conducted. After 47.1±25.8 months of follow-up, urethrocutaneous fistula were found in 23 (12.8%) patients associated with posterior hypospadias occurrence ( p=0.025), longer urethral defect ( p=0.007) and preoperative pyuria ( p<0.001). Chordee degree ( p=0.886) and age ( p=0.187) were not significant factors associated with urethrocutaneous fistula formation.

Conclusion:

Single-stage urethroplasty is a versatile procedure for various hypospadias cases, with a urethrocutaneous fistula rate of 12.8%. Posterior hypospadias, preoperative pyuria and longer urethral defect were associated with urethrocutaneous fistula formation.

Level of evidence

Risk factors for urethrocutaneous fistula following hypospadias repair surgery in Indonesia

INTRODUCTION

Hypospadias is one of the most common congenital malformations with a worldwide increasing trend over the years. Despite advancements in hypospadias repair, complications still occur. One of the most common complications of hypospadias repair surgery is Urethrocutaneous fistula. Studies attempting to analyze the association between the complication and risk factors are always beneficial, especially for studies performed in different areas of the world. We hypothesize that several evaluated risk factors among Indonesian hypospadias patients could be associated with the occurrence of urethrocutaneous fistula after the repair procedure.

OBJECTIVE

To determine the risk factors associated with urethrocutaneous fistula after hypospadias repair surgery by collecting and analyzing data obtained from multiple centers in Indonesia.

MATERIALS AND METHODS

A nationwide, retrospective study with 12 hospitals in Indonesia of children with a diagnosis of hypospadias was conducted. The collected data, taken from patients admitted in 2018, from each center's medical records consisted of patient identity, repair technique used, neourethra length, percutaneous cystostomy, and splint size as independent variables speculated to be possible risk factors correlated to the presence of urethrocutaneous fistulae. Binomial logistic regression analysis was performed using SPSS 21.0 to determine the relationship between urethrocutaneous fistulae as a post-repair complication and possible risk factors.

RESULTS

We collected 591 hypospadias cases from 12 centers in 9 cities in Indonesia. Most patients came when they were already at the age of more than four years old (60.4%). The chordee-only and failed urethroplasty groups are excluded from the analysis as they are not classified as true hypospadias. Most repairs were performed by using the Tubular Incised Plate (TIP) with Thiersch-Duplay technique (44.16%). Most of the reconstructed neourethra are 2-3 cm in length (32.13%). The 8 Fr urethral splint (46.41%) was mostly used during the operation. Most surgeons decided not to perform cystostomy throughout the procedure (61.03%) based on personal preferences. Urethrocutaneous fistula was found in 80 patients (15.27%) out of the total patients who underwent the surgery. The binomial logistic regression analysis shows that age (OR = 1.398, p = 0.015), the decision to not perform cystostomy (OR = 2.963, p = 0.014), and splint size (OR = 1.243, p = 0.023) are significantly associated (p < 0.05) with the development of urethrocutaneous fistula.

CONCLUSION

Age and splint size are significant risk factors for urethrocutaneous fistula after hypospadias repair in Indonesia, whereas performing percutaneous cystostomy during the repair decreases the risk for urethrocutaneous fistula occurrence.

Predictive Factors for Improved Renal Function in Renal Transplantation Recipients

OBJECTIVE

The purpose of this study is to analyze varying predictive factors for improved graft function among renal transplant recipients.

METHODS

Two hundred eleven consecutive donor and recipient pairs who underwent renal transplantation between January 2011 and December 2015 were enrolled in our study. Factors that affected renal graft function were analyzed. Statistical analyses were performed using SPSS version 16.0 software (SPSS Inc, Chicago, IL, United States).

RESULTS

The mean age of donors in years was 30 (range, 17-62), with a mean body mass index (BMI) of 23.20 kg/m² (range, 16.10-39.50). Mean total warm ischemic time in minutes was 44.80 (range, 26.10-83.45). The mean age of the recipients in years was 48 (range, 12-78) with a mean BMI of 22 kg/m² (range, 14.80-37.30). Estimated glomerular filtration rate at 6 and 12 months post-transplantation were 69 mL per minute per 1.73 m² (range, 10-137) and 65 (range, 16-110), respectively. Based on several parameters, there was no significant factor that improved renal graft function at 6 and 12 months after transplant. Total warm ischemic time almost showed statistical significance in predicting improved renal graft function after transplant. Future study with a longer period of observation and a larger sample size should be done for further investigation.

CONCLUSIONS

Total warm ischemic time is a promising parameter to predict improved renal graft function post-transplantation.

Common Practice of Hypospadias Management by Pediatric Urologists in Indonesia: A Multi-center Descriptive Study from Referral Hospitals

BACKGROUND:

Hypospadias is the second most common congenital anomalies among human congenital disabilities. There are over 300 surgery techniques being introduced to treat hypospadias. The successful of hypospadias repair is assessed by several outcomes as well as complications following surgery.

AIM:

This study aims to show the multicenter hypospadias data in Indonesia descriptively.

METHODS:

All the data were compiled based on questionnaires, which were distributed to Indonesian pediatric urologists. The questionnaire includes several questions containing demographic aspect, preferred techniques being used, and complications being found regarding hypospadias repair.

RESULTS:

Eighteen Indonesian pediatric urologists from 12 centres involved in this study. The data were collected from June – September 2018 based on the surgeon’s experience throughout 2017. From 591 cases based on the returned questionnaire, penile-type hypospadias was the most common type of hypospadias being treated (35.7%) followed by penoscrotal (28.9%) and scrotal-type (12.9%). Moderate severity of chordee was mostly seen among all cases (40.6%). Tubularised incised plate (TIP), + Thiersch Duplay, was the most common technique being used to treat hypospadias (44.3%), followed by onlay island preputial flap (14.9%) and two-stage technique (14%). The incidence of urethrocutaneous fistulae in this study was 13.9%.

CONCLUSION:

This study showed how Indonesian pediatric urologists dealt with hypospadias cases. TIP + Thiersch Duplay procedure being the preferred technique used by most participants and the rate of urethrocutaneous fistulae as one of the complications was comparable with previous studies.

Renal transplantation with duplicated ureters: A case report

We reported a case in which a renal allograft with duplicated ureters from a 25-year old donor were successfully transplanted into a 38-year old recipient with combination of spatulation and side-to-side anastomosis of the duplicated ureters with Lich-Gregoir technique for ureteroneocystostomy of the transplantation. There was no complication after the transplant. The recipient's post-operative course remains uneventful at more than 4 months with serum creatinine 1.35 mg/dL.

Extrarenal calyces mimicking retroperitoneal cystic mass with concomitant ureteropelvic junction obstruction: renal pelvis reconstruction using calyx unification

Extrarenal calyces (ERCs) are a very rare urological anomaly, especially when concomitantly presenting with ureteropelvic junction obstruction (UPJO). Surgical intervention is often necessary in ERCs associated with UPJO, with dismembered pyeloplasty being the most commonly utilized technique. We present a case of UPJO-associated ERCs in which renal pelvis reconstruction using calyx unification was selected as the treatment technique. An 11-year-old boy was referred to our center due to bilateral hydronephrosis and left multicystic kidney disease. Magnetic resonance imaging showed severe left hydronephrosis with concomitant left cystic mass and left UPJO. A ^99mTc diethylenetriaminepentaacetic diuretic renal scan showed residual renal function of 25.9% split function and 26.8 mL/minute glomerular filtration rate. Intraoperatively, we found ERCs with severely dilated renal pelvis. The renal pelvis was excised. Major calyces protruding from the kidney were unified using side-to-side anastomosis to form a new structure resembling a renal pelvis, which was further anastomosed to the ureter. Temporary urinary drainage from the affected kidney was achieved using a double-J (DJ) stent and nephrostomy. Pathological examination revealed atrophic transitional epithelial cells. There was no intra- or postoperative complication reported. The nephrostomy tube and DJ stent were removed 2 weeks and 3 months after surgery, respectively. Ultrasonography examination performed at 1 and 9 months after DJ-stent removal showed no hydronephrosis. We conclude that renal pelvis reconstruction using calyx unification can be performed safely and is effective in treating patients with ERCs associated with PUJO. This technique should be considered especially in cases where excision of the renal pelvis cannot be avoided.

Association between Early Resistive Index Measurement and Early Graft Function and Long-Term Graft Survival after Kidney Transplantation: an Evidence-based Clinical Review

BACKGROUND

resistive index (RI) is highly utilised to assess the graft function using Doppler ultrasonography. The RI has been shown as the best ultrasound parameter to assess kidney allograft dysfunction. Several studies have established the role of the RI as a predictor of transplant failure. However, these studies were using RI measurement in the later stages post transplantation. The present study has conducted to identify the association between early RI measurement and early graft function represented as delayed graft function (DGF) and immediate graft function (IGF), as well as long-term graft survival.

METHODS

an evidence-based clinical review of studies published before May 2018 was conducted from Medline, Science Direct, EMBASE and Cochrane databases. Studies on early measurement of RI whereby the primary or secondary goals of the study related to graft function and/or graft survival were included. Studies using late RI measurement and without RI value groups were excluded. The Mantzel-Haenzel method was used to analyse pooled risk ratio and 95% confidence interval, while the heterogeneity of the study was calculated through I2 value. Data analysis was performed using Review Manager 5.3.

RESULTS

nine studies with a total of 1802 patients who had undergone a kidney transplant were analysed. DGF was found in 19% (193/1015) of the low RI group and in 42.8% (337/787) of the high RI group (RR 2.04 (95% CI 1.72 - 2.41), p < 0.00001, I2 = 28%). IGF was found in 39.5% (62/157) of the low RI group and in 10.5% (28/268) of the high RI group (RR 0.26 (95% CI 0.17 - 0.40), p < 0.00001, I2 = 0%). Long-term graft survival, with follow up between 60-144 months, was found in 83% (701/845) of the low RI group and in 69.4% (395/569) of the high RI group (RR 0.82 (95% CI 0.72 - 0.93), p = 0.002, I2 = 63%).

CONCLUSION

the results of this study emphasise the association between early measurement of RI and early graft function, and long-term graft survival. An elevated RI provides the chance of recognizing the patients with poor long-term prognosis, from the first moment after kidney transplant.

Abnormal dartos fascia in buried penis and hypospadias: Evidence from histopathology

INTRODUCTION

The importance of the pathology of the dartos fascia in hypospadias and buried penis is still debatable. Understanding the properties of connective tissue of dartos fascia in hypospadias and buried penis may give a clue to the underlying mechanism.

OBJECTIVE

This study aimed to compare connective tissue and vascularization of dartos fascia between normal penis, buried penis, and hypospadias.

STUDY DESIGN

We conducted this prospective study from May 2013 to November 2016. We collected dartos fascia specimens from three groups: buried penis, hypospadias, and normal penis as control. All of the patients underwent primary surgery in all groups. Patients with penile abnormalities, such as phimosis or Balanitis Xerotica Obliterans (BXO) were excluded from the normal penis group. We compared the fibers between these groups using Masson trichrome histochemical staining, Gomori's silver impregnation staining, Weigert resorcin-fuchsin staining, and CD31 immunohistochemistry staining for evaluation of collagen fibers, reticulin fibers, elastin fibers, and endothelial cells of blood vessels, respectively. The collagen fibers, reticular fibers, elastic fibers, and vascular vessels were counted with ImageJ and manually calibrated and counted and were analyzed using the one-way ANOVA test. The assessment conducted by two pathologists was blinded, without knowing the clinical diagnosis of patients.

RESULTS

There was a total of 60 patients with 20 patients in each group. Collagen fibers for most cases of buried penis and hypospadias showed thicker but fewer collagen fibers than the normal penis. There was a reduction of total collagen and elastin of dartos fascia in hypospadias and buried penis cases. On the other hand, the ratio of reticulin fibers, which represents collagen type III to total collagen, was increased compared to normal penis.

DISCUSSION

Although the dartos fascia in buried penis and hypospadias is thick and inelastic when palpated or during traction/counter traction, it is well-vascularized tissue. This inelastic dartos fascia tissue is an abnormal tissue, but its characteristics are not similar to fibrotic tissue. However, further study with a larger sample is warranted and should differentiate the degree of chordee in patients with hypospadias and buried penis.

CONCLUSIONS

There was a difference between connective the tissue of dartos fascia in buried penis and patients with hypospadias compared with normal penis. Inelastic dartos fascia tissue in patients diagnosed with buried penis and hypospadias is an abnormal tissue. Therefore, it is suggested that this tissue is excised during reconstructive surgery. Further research is needed to unveil the pathophysiology of the condition.

Milestones of kidney transplantation in Indonesia

Although kidney transplantation in Indonesia has started since 1977, it has only covered less than 3% ESRD treatment methods. This indicates that the development of kidney transplantation program in Indonesia is still stagnant. Based on observation, the growth of kidney transplantation in Indonesia can be divided into several eras, which are: the birth of new treatment for ESRD era, the expected growth era, the first downfall, the stable period, the unstable period, the rebirth of kidney transplant era, and the explosive growth era. Many factors contribute to this issue including the government policy, the funding problems, the limited donor pool, the dissenting cultural views, the number of human resources, the need for multi-disciplinary approach, and the life-after-graft care. However, many improvements have been made to increase kidney transplantation i.e. the government support for opening new kidney transplant centers, the use of minimally invasive techniques, the development of pediatric kidney transplant, and National Insurance coverage for transplantation. These conditions are expected to improve the number of kidney transplantation in Indonesia.

Childhood renal cell carcinoma

Renal cell carcinoma (RCC) in children isseldom found. The incidence of thistumor in childhood is estimated to be 0.1-0.3% out of all neoplasms and 2-7% out ofall malignant renal tumors. The Third NationalCancer Survey reported an incidence of only four casesof RCC per year compared to 117 per year of Wilms’tumor.The incidence of RCC has not been reported inIndonesia. This is the first case of childhood RCCfound in our institution. To the best of our knowl-edge, this is the first report of childhood RCC in In-donesia.

Comparison Between End-to-end Anastomosis and Buccal Mucosa Graft in Short Segment Bulbar Urethral Stricture: a Meta-analysis Study

AIM

to compare long term follow-up between end-to-end urethroplasty and bucal mucosal graft for the management of patients with short bulbar urethral stricture.

METHODS

we conducted a meta-analysis of cohort studies. Literature research was performed on the MEDLINE, Science Direct, and EMBASE database including studies from 1980 through 2014. The inclusion criteria were patients with short bulbar urethral strictrure (sized 3 cm) undergoing end-to-end anastomosis (EE) and buccal mucosa graft (BMG) with the complication of voiding symptoms and sexual dysfunction 12 months. Pooled risk ratio (RRs) and 95% confidence interval (CIs) were calculated using Mantzel-Haenzel method, while the heterogeneity were determined through I2 value. Data analysis were done using Stata software version 10.0 (StataCorp).

RESULTS

We analyze 10 studies in this meta-analysis. Sexual dysfunction following EE and BMG were found in 24.6% (45/183) patients and 9.1% (11/122) patients, respectively (overall RR 2.54; 95% CI: 1,44-4,47; p=0.001). Voiding symptoms following EE and BMG were found in 14% (8/57) patients and 12.5% (7/56) patients, respectively (overall RR 0.77; 95% CI: 0.3-2.0; p=0.591). Furthermore, stricture recurrent following EE and BMG were 8.4% (8/107) and 30% (14/46), respectively (overall RR 0.38; 95% CI: 0.17-0.84; p=0.016). The effectiveness of EE and BMG were found to be equal as both demonstrated few complications. BMG were found to be superior than EE terms of minimal sexual dysfunction complication. On the contrary, EE were found to be superior than BMG in terms of stricture recurence following short bulbar urethral stricture surgery.

CONCLUSION

BMG can be considered as the primary treatment rather than EE for managing short urethral stricture cases.

The management of vesicoureteral reflux in children

Vesicoureteral reflux (VUR) is defined as retrograde flow of urine from the bladder to the ureter.  It is usually asymptomatic but commonly found in children with urinary tract infection (UTI). The prevalence is about 1-2% in general pediatric population.1 However, the prevalence in children with UTI is much higher, reaching 30-57%.1,2 Similar prevalence (45.8%) is also reported in CiptoMangunkusumo Hospital. 3

Female epispadias: are we missing the diagnosis?

OBJECTIVE

To describe three of four female patients with occult epispadias, as usually epispadias is reported to be a rare condition in females (1/480,000), and obvious and easy to diagnose, but less severe variants may still involve urethral sphincter incompetence in the absence of obvious clinical signs.

PATIENTS AND METHODS

The hospital records over a 10-year period (1 January 1991 to 31 December 2000) were reviewed to find all female patients diagnosed with epispadias. Data were collected from the Consultative Council on Obstetric and Paediatric Mortality and Morbidity for the number of live births per year for the decade studied, and the incidence of female epispadias determined.

RESULTS

Over the 10-year period there were 13 patients with a diagnosis of epispadias, from 636,698 total live births; four were female and nine male. Each of the female patients had varying degrees of epispadias; three had subtle signs with apparently normal external genitalia, and only one had a bifid clitoris. However, even the most minor variant case had a palpable notch in the symphysis pubis, and an 'oblong' external urethral meatus. Thus the incidence of female epispadias is at least 1/160,000.

CONCLUSION

Epispadias in females may be up to three times more common than previously expected, but even experienced clinicians can miss the diagnosis. The importance of a careful examination should be emphasized, especially in female patients with chronic wetting of unknown cause. A bifid clitoris is an important sign but not always present. Key diagnostic features include drug-resistant wetting, a very low leak pressure on cystometrography, a palpable gap in the pubic symphysis and an abnormal oval-shaped external urethral meatus.
