Can We Predict Renal Function Recovery After Pyeloplasty in Pediatrics with Ureteropelvic Junction Obstruction? A Systematic Review.

Chronic unilateral renal obstruction, primarily caused by ureteropelvic junction obstruction (UPJO), poses challenges in determining the optimal timing for corrective surgery. The goal is to preserve renal function and alleviate symptoms, but there is no definitive diagnostic test to reliably predict the outcomes of surgery. This systematic review aimed to identify predictors for renal function recovery after pyeloplasty in order to guide effective treatment options. We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A literature search was performed on PubMed, Embase, and Scopus using keywords related to renal function, pyeloplasty, and predictors. The search was conducted on March 10, 2022. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. Out of 344 potentially relevant articles, 11 met the eligibility criteria for this study. These included 6 retrospective and 5 prospective studies, with a total of 925 participants. Most studies evaluated renal function using differential renal function (DRF). The overall quality of the included studies was considered average. The findings indicated that age at the time of surgery and gender did not significantly influence functional recovery after pyeloplasty. However, preoperative DRF consistently emerged as a critical predictor. Preoperative DRF can serve as the most common predictors used for renal function recovery following pyeloplasty. These findings contribute to understanding effective treatment options for chronic unilateral renal obstruction. However, further research for each predictor is needed to validate these predictors and their clinical utility. Cite this article as: Siregar S, Mustafa A, Steven S.

The challenges in diagnosing isolated epididymal tuberculosis (TB) in an adolescent male: a case report.

BACKGROUND: Genitourinary tuberculosis (GUTB) is a common form of extrapulmonary TB (EPTB) in children. An example of GUTB is epididymal TB, which usually presents unspecific chronic clinical manifestations. Definitive diagnosis can be conducted based on bacteriologic confirmation and histopathologic results, but this is challenging due to the paucibacillary nature of EPTB. Therefore, we reported the challenges in diagnosing isolated epididymal TB in an adolescent male. CASE PRESENTATION: A 16-year-old male presented to respirology clinic with painful swelling of the left scrotum for 3 months before visiting to the hospital. The symptoms were associated with persistent coughing for 2 months, and physical examination of the left scrotum showed swelling accompanied by cardinal signs. A palpable hard mass was found on the left scrotum, with firm borders, measuring 7 × 4 cm. Laboratory examination and tumor markers were within normal limits, although leukocyturia was found, and the urine culture was negative. Genital ultrasound (US) showed epididymitis sinistra with septal hydrocele, while magnetic resonance imaging (MRI) indicated inhomogeneous left epididymitis with bilateral inguinal lymph node enlargement. Although TB evaluation presented a negative purified protein derivative (PPD) test and bacteriologic examination, chest X-ray (CXR) showed perihilar lymphadenopathy. Based on the clinical and radiologic results suggesting TB, the patient was diagnosed with isolated epididymal TB and received quadruple antituberculosis therapy (ATT) for 6 months. After treatment, the left testicle size started to shrink and was equal to the right testicle, also, there were no signs of inflammation, the body weight increased by 5 kg, and cough disappeared. Sperm analysis at the end of treatment indicated teratozoospermia, which was subsequently treated by the urologic surgery department. CONCLUSIONS: Biopsy and bacteriologic confirmation for TB epididymitis were challenging to perform in the clinical setting. Epididymal TB should be considered in adolescent males with complaints of chronic scrotal swelling and pain. Clinical judgment based on history taking, physical examination, and radiologic features supporting TB features could be helpful in accurate and fast diagnosis for favorable outcome.

2,8-Dihydroxyadenine nephrolithiasis with chronic kidney disease in children: A case report and review of literature.

The incidence of nephrolithiasis in children ranges from 5 to 10% in developing countries. Etiology of nephrolithiasis in children remains largely unknown, so metabolic evaluation is indicated in all case, because of potential morbidity and recurrence. We report a case of 2,8-Dihydroxyadenine nephrolithiasis present as bilateral staghorn stone in 11 years old boy with chronic kidney disease. 2,8-Dihydroxyadenine nephrolithiasis is the result of a metabolic abnormality due to the deficiency of the enzyme adenine phosphoribosyltransferase (APRT), it is not only promote stone formation, but also induced nephropathy. Early diagnosis ensure appropriate treatment and favorable prognosis for kidney function and stone management.

Comparison between staged laparoscopic technique in children with high intra-abdominal undescended testis: a systematic review and meta-analysis.

Background: This study performed a systematic review and meta-analysis to compare the outcomes of the staged laparoscopic Fowler-Stephens Laparoscopic Orchiopexy (FSLO) and Staged Laparoscopic Traction Orchiopexy (SLTO) in patients with intra-abdominal testes (IAT). Methods: This study reviewed literature published from 2016 to 2024. A systematic literature search was conducted on three databases: PubMed, ScienceDirect, and Google Scholar, using keywords (High intra abdominal testis) AND (("Fowler Stephens laparoscopic orchiopexy" OR (FSLO)) OR (Staged Laparoscopic traction orchiopexy OR (SLTO)). Non-randomized trials and observational studies comparing staged laparoscopic FSLO and SLTO, without any time range restriction are included. Studies without FLSO orchidopexy as a control, case reports, case studies, duplicate publication, no full text and non-English studies are excluded. This study used the PRISMA protocol, the Jadad Scale, and the Newcastle Ottawa Scale (NOS) to evaluate the included studies. To analyze statistical data, the Review Manager (RevMan) software was used. The Chi-squared test was used to calculate statistical heterogeneity in the meta-analysis. Results: There were 240 patients from 5 studies (109 in the SLTO group and 131 FSLO in group). The primary outcome of this study is testicular descent and atrophy. There were no significant differences in testicular descent (RR:1.08[0.96 - 1.23],p<0.20,I 2:0%) and atrophy rate (RR:0.45[0.19 - 1.09],p<0.08,I 2:0%). Secondary outcomes are the duration of operation in both the first and second stages. Statistical analysis reveals a significantly lower first-stage operation time in the FSLO group (MD:9.31[7.08,11.55], p<0.05;I 2:94%). At the same time, lower second-stage operation times are significantly reported in the SLTO group (MD:-4.05[-7.99,-0.12],p<0.05; I 2:60%). Conclusions: In terms of testicular descent and testicular atrophy the SLTO technique yields similar results to the FSLO technique. Both techniques have advantages and disadvantages, and we recommend SLTO as the first choice in children with a high IAT of <4 cm. PROSPERO registration: CRD42023412407.

Conclusion: Stem cell therapy has a good therapeutic potential in erectile dysfunction, the available data from the literature could be the base of usage of stem cells in the treatment of erectile dysfunction although need more research for broader usage.

Antioxidant Supplementation on Sperm DNA Fragmentation and Sperm Parameters: A Systematic Review and Meta-Analysis.

OBJECTIVE: Infertility affects about 15% of couples in reproductive age worldwide. Male factors are the main causes for this condition. Antioxidants have long been used for infertility treatment as they are easily available with a low cost. In this systematic review, we focused on the relation between antioxidant supplementation and sperm DNA fragmentation and other sperm parameters. MATERIAL AND METHODS: An online search from PubMed and ScienceDirect databases was conducted by 2 reviewers. We reviewed full-text articles to obtain detailed information. RESULTS: Nine articles were included in this study. Four studies revealed a statistically significant reduction of sperm DNA fragmentation and five studies revealed an insignificant decrease of sperm DNA fragmentation. Sperm concentration, sperm motility, and morphology were also increased after antioxidant supplementation. Pregnancy rates were reported in 3 studies; the rates increased in 2 studies, and similar rate to placebo group was observed in 1 study. CONCLUSION: Antioxidant supplementation can counteract against oxidative stress and improve spermatogenesis process reflected by decrease of DNA Fragmentation Index (DFI), improvement of sperm parameters, and elevation of pregnancy rates confirmed by those included studies.

Congenital anterior urethrocutaneous fistulas with chordee: A case report.

Congenital anterior urethrocutanous fistula is a rare genitourinary malformation with unknown etiology and may present as an isolated form or in association with hypospadias or chordee. We describe a case of congenital anterior urethrocutanous fistula with chordee variants in a 5-year-old boy. The patient successfully underwent chordectomy and urethroplasty with no adverse outcomes. We report a review of the literature about the etiology and surgical intervention especially with chordee variants. The congenital anterior urethrocutanous fistula is a rare anomaly with unkown etiopathogenesis.

Microsurgical varicocelectomy effects on sperm DNA fragmentation and sperm parameters in infertile male patients: A systematic review and meta-analysis of more recent evidence.

BACKGROUND: Varicocele is known to have impacts in infertility cases and sperm quality. This review aimed to evaluate the effects of microsurgical varicocelectomy on sperm DNA fragmentation index (DFI) and sperm parameters. METHODS: Open full English text articles from January 2017 to October 2021 were searched from online database including PubMed, EMBASE, Scopus, Cochrane Library and Google Scholar. RESULTS: Systematic search resulted in 277 potential papers. After throughout paper analysis, 5 studies were included in this review. From all five analyzed studies, microsurgical varicocelectomy was statistically proven to reduce DNA fragmentation index by 5.46% (mean difference -5.46; 95% CI: -4.79, -6.13; p < 0.00001). Moreover, the procedure also significantly improved other sperm parameters (sperm concentration +8.23%, sperm motility +7.17%, sperm progressive motility +2.77%, sperm morphology +0.64%). CONCLUSION: Microsurgical varicocelectomy significantly improves spermatogenesis as reflected by biomarkers of infertile men including semen parameters and sperm DNA fragmentation (SDF).

The Role of Maternal and Environmental Factors During Pregnancy on the Risk of Hypospadias Occurrence.

Introduction and Objectives: Hypospadias is a congenital disorder in boys in which the urethral meatus is located on the ventral penis. The incidence rate of hypospadias is increasing, however, there is still no literature regarding how significant is the role of maternal and environmental factors to the risk of hypospadias, especially in Indonesia. This study aims to analyze the maternal and environmental factors during pregnancy to the risk of hypospadias. Materials and Methods: This study was an analytical observational study with a case control design. The subjects were mothers who gave birth to children with hypospadias, compared to normal, who visited the urology, pediatric-surgery, plastic-surgery, and pediatric clinic at Hasan Sadikin General Hospital. Results: A total of 120 samples (60 cases and 60 control) were included in this study. There were 14 maternal factors, which 5 of them found significantly correlated with hypospadias, including maternal occupation as an industrial worker (P = .003; OR:4.789), pregnancy-enhancing drugs usage (P = .004; OR: 5.783), smoking consumption (P = .034; OR: 2.294), mosquito-repellant usage (P = .0001; OR: 82.600), and preterm birth (P = .013; OR: 2.895). There were 2 environmental factors, and one of them was significant, which was the distance from home to industrial/rice fields/waste areas, approximately 780 m (P = .0001; OR: 6.102). Based on multivariate analysis, we found that maternal occupation, mosquito repellent usage, and the distance from home to industrial area had a strong relationship in predicting hypospadias occurrence. Conclusion: Several maternal and environmental factors were found significantly correlated to hypospadias occurrence. Among these, mosquito-repellant usage was found to be the most significant factor.

Testicular Epidermoid Cyst: A Rare Case Report.

INTRODUCTION AN IMPORTANCE: Testicular epidermoid cysts (TECs) are rare benign testicular neoplasms. Recently, testicular epidermoid cysts (TECs) are listed as teratoma of prepubertal type, however it is still difficult to differentiate the epidermoid cyst from malign testicular tumor. Therefore, we would like to report testicular epidermoid cyst at our institution. CASE PRESENTATION: A 67-year-old man from Indonesia, presented with chronical painless mass of testis since one year ago. On physical examination obtained normal penile structure with descended testicles, palpable intrascrotal mass with size of 10 × 7 × 5 cm, firm consistency, immobile, without any tenderness, and no lymphadenophaty in groin. Scrotal USG showed intratesticular mass, homogenous parenchym, showed no vascularization during Doppler examination. Histopathological examination revealed the specimen of right scrotum with size of 12.5 cm × 8.5 cm × 6.1 cm with red-brownish colored, during lamellation, obtained encapsulated mass with size of 12.2 cm × 7.9 cm × 6 cm, hollowed space filled with porridge-like texture with capsule thickness of 0.1-0.3 cm. CLINICAL DISCUSSION: Epidermoid cysts are benign lesions occurring on the skin usually, however, it rarely occurs in intratesticular area. Most of the cases (60%) presented with the typical onion-ring phenomenon. Histopathological findings commonly revealed typical well-defined cyst lined by a fibrous membrane. No skin appendages are found in the cyst's lumen and no germ cell neoplasm (GCN) is present in the adjacent testicular parenchyma. CONCLUSION: All testicular masses are considered malignant until proven otherwise. It is necessary to do accurate diagnosis for the prevention of unnecessary radical orchiectomy.

Role of human adipose-derived stem cells (hADSC) on TGF-ß1, type I collagen, and fibrosis degree in bladder obstruction model of Wistar rats.

INTRODUCTION: Bladder outlet obstruction (BOO) was caused by a series of histological and biochemical changes in the bladder wall, through the inflammation process in the bladder wall, hypertrophy and fibrosis. ADSC has an important role in bladder regeneration. METHODS AND MATERIALS: This study was an experimental randomized study using male Wistar rats which were monitored at 2 and 4 weeks to determine the effect of ADSC therapy on TGF-ß1 type I collagen, and degree of fibrosis. RESULT: Rats were divided into 5 groups. In the week 2 BOO group, 1 sample included in the category of moderate fibrosis, 1 sample that was given ADSC with mild fibrosis category, 3 samples included in severe fibrosis category, 3 samples that were given ADSC included in the category of moderate fibrosis. The concentration of TGF-ß1 in the hADSC therapy group was significantly lower than the control group at the 2nd and 4th week of monitoring (p2 = 0.048, p4 = 0.048), and also with more type I collagen on 2nd and the 4th week (p2 = 0.048, p4 = 0.048). CONCLUSION: ADSC therapy can reduce the concentration of TGF-ß1, type I collagen, and degree of fibrosis in the male Wistar BOO model.

The role of angiotensin receptor blocker (losartan) on decreasing fibrotic process of corpora cavernosa in priapism model of wistar rats.

Background: Priapism induces regulation of Transforming Growth Factor-ß1 (TGF-ß1) expression and collagen-type-1 deposition. This will replace the normal corpora cavernosa with fibrotic tissue which eventually resulted in erectile dysfunction. It is also known that the fibrosis process of corpora cavernosa is related to Renin-Angiotensin II System (RAS). Angiotensin II receptor blockers (ARB), especially losartan, inhibit the inflammation process and fibrotic tissue formation. This study evaluated the effect of losartan in reducing fibrosis in priapism by evaluating TGF-ß1 and collagen-type-1 in cavernous tissue and determined the effect of losartan in preventing fibrosis in priapism model of Wistar rats assessed by the metavir score. Methods: A total of eighteen male Wistar rats mean were divided into five groups. For the priapism models, we applied negative pressure on the penis to make an artificial erection to mimic the priapism process. The control groups were observed and the treatment groups were orally given losartan 15 mg/kg/day. Corpora cavernosa was harvested for TGF-ß1 and collagen-type-1 measurement using an enzyme-linked immunosorbent assay (ELISA). The fibrotic tissue of each rat was then collected and assessed histopathologically with the metavir scoring system. Results: Penile TGF-ß1 concentration in the losartan-treated group was not significantly different on day 10 and day 28 of observation (p10=0,30; p28=0,17). Meanwhile, collagen-type-1 concentration was significantly lower compared to control group (p10=0,002; p28=0,01). There was a significant difference in metavir scores in rats that received losartan and those who did not (p<0,05). Conclusion: Losartan could suppress the fibrosis process in the priapism model. It could decrease the collagen type 1 deposition during corpora cavernosa tissue regeneration. Based on the metavir score, the group receiving losartan therapy was better than the control group.

The benefit of tissue sealant on urethroplasty in hypospadias patients - A systematic review and meta-analysis.

Background: Hypospadias was ranked second after undescended testis as the most prevalent congenital abnormality in newborn males. Hypospadias can be successfully repaired through multiple surgeries in the majority of children. Postoperative complications were not rarely seen after surgeries, such as urethrocutaneous fistula (UCF), meatal stenosis, and glans breakdown. Tissue sealant application in hypospadias repair serves as additional suture line coverage and reduces the post surgery complications. However, the effects of sealants usage during urethroplasty are still uncertain. This review aimed to know the effects of tissue sealant usage on patients with hypospadias who undergo urethroplasty. Methods: The study was reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Literature was searched on PubMed, Embase, and Scopus following PRISMA guidelines. The search was conducted on October 12th, 2021, using the search term ("glue" OR "sealants" OR "tissue glue" OR "tissue sealant" OR "tissue adhesive") AND ("hypospadias" OR "urethrocutaneous fistula" OR "urethral repair" OR "urethroplasty" OR "hypospadiology"). Result: Systematic searching from all databases resulted in 160 potential articles. After a full-text review, eight articles were included in this study. Urethrocytaneous fistula complication was reported in all studies. The occurrence of complication reported by all studies was urethrocutaneous fistula. Several studies also reported tissue edema and flap-related complications. Tissue sealant had no significant effect in reducing meatal stenosis. Conclusions: This systematic review revealed additional benefits from several types of tissue sealant in hypospadias repair surgery. Fibrin sealant application over the urethroplasty suture line in hypospadias repair offers a water-proof coverage and may enhance the outcome from the surgery.

The Effect of Intratesticular Injection of Human Adipose-Derived Mesenchymal Cell on Testicular Oxidative Stress and Spermatogenesis Process in the Varicocele Rat Model.

INTRODUCTION: Varicocele is the predominant cause of male infertility. Reactive oxygen species was found in varicocele which induce the lipid peroxidation process in the plasma membrane of spermatozoa and may cause damage to spermatozoa in semen and seminiferous tubules, disrupting spermatogenesis. Human adipose derived stem cells (hADSC) can suppress oxidative stress in some oxidative injury model. This study investigate the effect of intratesticular hADSC injection on malondialdehyde (MDA) level and spermatogenesis process by histopathological examination in the varicocele rat model. METHODS: This is an experimental study. A total sampling of 9 male Wistar rats were divided into three groups. Group I consist of 1 Wistar rats without any treatment or model (sham group), group II consist of 4 Wistar rats with varicocele model without hADSC therapy (control group), and group III consist of 4 Wistar rats with varicocele model and were given injections of 1.0×106 hADSC cells intratesticularly 30 days after model was made (therapy group). Testicular tissue was harvested for evaluation. RESULTS: In all varicocele model rats (group II and III), the result of MDA level in therapy group (2.53 mol/liter) was significantly lower than the MDA level in control group (4.43 mol/liter) (p = 0.01). On histopathological examination, the average Johnson's Score in the therapy and control group was 9.77 and 9.18, respectively. The analysis showed Johnson's score in the intervention group was significantly higher (p = 0.018). CONCLUSION: Intratesticular injection of hADSC can help reduce MDA levels and improve spermatogenesis process, which is damaged by varicoceles.

Uterus as one of the ectopic ureter openings: Case report.

Ectopic ureter is defined as any ureter, single or duplex, that does not open in the trigonal region of the bladder. A 19-years-old girl was presented with urinary incontinence. Physical examination revealed a normal urethral meatus with pooling of urine at the introitus. A Kidney-Ureter-Bladder ultrasound revealed a duplex-system suspicion on the right side. The patient was managed by laparoscopic heminephrectomy of right ureter. The uterus gains its normal shape and sized without any fluid filling after the operative being completed. In conclusion, a complete diagnostic work up is important to achieve better prognosis and early treatment.

Correlation of Visceral Obesity and Interleukin-6 Level on LUTS Due to Benign Prostatic Enlargement.

BACKGROUND: Benign prostatic enlargement (BPE) is a common condition in older men causing lower urinary tract symptoms (LUTS). Numerous studies have shown correlations of obesity and age as risk factors of LUTS due to BPE. However, there are only a few studies showing the increase of interleukin-6 (IL-6) as a risk factor in LUTS. IL-6 expression is regulated in the prostate. IL-6 was found to be increased in several conditions, such as infection, inflammation, and obesity. The aim of this study is to correlate visceral obesity and IL-6 expression in the prostate with BPE and LUTS. METHODS: We analyzed the correlation of the Visceral Adiposity Index (VAI) and IL-6 of 52 patients with LUTS due to BPE. Statistical analysis was tested using an independent t-test. Data were analyzed with SPSS ver 20.1. RESULTS: Of 52 BPE subjects, who had not received any therapy, 16 patients presented with severe LUTS (30.77%), while the remaining 69.23% had mild-moderate LUTS complaints. IL-6 examination showed that obese patients and severe LUTS had higher IL-6, with p=0.032 and 0.01, respectively. Correlation analysis showed a weak correlation between IL-6 and obesity (r=0.179, p=0.02). Based on regression study, it was found that the risk for a patient with visceral obesity to develop severe LUTS is 5-times higher than normal (p=0.017). CONCLUSION: This study found a correlation between the degree of visceral obesity assessed by VAI and IL-6 levels in BPE patients. In addition, there is also a correlation between the degree of visceral obesity and IL-6 levels on LUTS severity in people with BPE.

Validation of FGSI Scores in Predicting Fournier Gangrene in Tertiary Hospital.

BACKGROUND AND AIM: Fournier gangrene (FG) is a necrotizing fasciitis of perineal and/or genital regions that may progressively spread; necrotic tissue may cause morbidity and mortality related to sepsis and multi-organ dysfunction. Surgical intervention required for patients with Fournier gangrene may vary according to the severity of the infection. A Fournier Gangrene Severity Index (FGSI) has been devised to assess the risk of mortality in patients with Fournier gangrene. The aim of this study was to validate the implementation of the FGSI in predicting mortality of FG patients in our hospital. METHODS: A retrospective study was performed on all patients with Fournier gangrene admitted and treated in Hasan Sadikin General Hospital during 2015-2019. Data were collected from the medical records of the emergency room and outpatient clinics. Sociodemographic variables, preexisting comorbidities, outcome, management, and FGSI score were included as variables. RESULTS: In this study, 83 patients were included from the period 2015-2019, divided into two groups. From the Charlson Comorbidity Index, we found the first group average score was 2.5 (0-9), and the second group this was 2 (1-8). From the FGSI, in the first group, we found the average score was 5.5 (2-15), and the average was 14 (10-19) in the second group, which is significantly higher than the first group (p = 0.001). CONCLUSION: We find that the FGSI score system is a good tool for predicting severity of the disease and mortality risk of the patients, which is consistent with findings in other studies.

Polymorphism of PvuII, Xba1, and SNP 12 Estrogen Receptor 1 (ESR1) in Hipospadias Patients at Tertiary Hospital Center.

INTRODUCTION: The prevalence of hypospadias ranges between 1: 250 to 300 per live birth. Estrogen exposure has been associated with the increasing incidence of hypospadias in humans and a significant relationship between Estrogen Receptor 1 (ESR1) polymorphisms and hypospadias was determined from the previous study. This study aims to determine the proportion of ESR1 polymorphism. METHODS: This was a descriptive study aimed to find the incidence of ESR1 gene polymorphism in hypospadias patients visiting the Urology Outpatient Unit of the Hasan Sadikin Bandung Hospital who will undergo hypospadias surgery. Deoxyribonucleic acid (DNA) was performed using foreskin of hypospadias patient during the surgery then being extracted and will be analyzed using polymerase chain reaction (PCR) sequencing. RESULTS: Thirty eight samples of hypospadias were identified, 5 samples were unable to sequence and 33 samples were successfully sequenced using the PCR method. The Pvull ESR1 gene was dominated by the T allele which is a wild-type allele and the genotype containing the T allele, namely TT + TC (57,2%). Normal genotype (TT) were more frequent in distal hypospadias, and Heterozygous polymorphisms (TC) was higher in proximal hypospadias. The ESR1 Xba1 gene polymorphism was dominated by the A allele which is a wild-type allele and the AA + AG genotype (76,1%). Normal genotype (AA) was more frequent in distal hypospadias, and both heterozygous hypospadias (AG) and homozygous hypospadias (GG) were found only in proximal hypospadias. The ESR1 SNP 12 gene polymorphisms were found in the combination of genotypes that played a role, namely GA + AA (81%) and the G allele which is a wild-type allele. Heterozygous polymorphisms (GA) was the most finding genotype and more frequent in proximal hypospadias. CONCLUSION: ESR1 gene polymorphisms (PvuII, XbaI, and SNP 12) were found in hypospadias patients. ESR1 polymorphisms may correlate with the severity of hypospadias. Further research with a larger sample and better hypospadias grouping is needed to confirm.

Penile strangulation injury by metallic ring: A study of 4 cases.

Penile strangulation by metallic ring is an emergency situation which requires urgent management. Strangulation of the penis usually performed in order to increase sexual performance or because underlying mental disorder or paraphilia. It is an uncommon urological emergency, if not treated as soon as possible it can lead to complications such as gangrene and amputation of the penis. There is no standard of care that has been found to be superior, with each case managed individually according to its clinical findings and operative settings. In this study, we present four cases of penile strangulation in last two years in a tertiary care hospital.

Intratesticular Human Adipose-Derived Stem Cell (hADSC) Transplantation Decreased Oxidative Stress in Testicular Torsion Model of Wistar Rat.

INTRODUCTION: Testicular torsion is a sudden rotation of the testis towards its axis, which causes the twisting of the spermatic cord. Post-detorsion reperfusion will cause inflammation and trigger oxidative stress, which generates reactive oxygen species (ROS). Malondialdehyde (MDA) is an organic compound formed from ROS frequently used as an oxidative stress biomarker during ischemia and ischemia-reperfusion injury. In some organs, stem cell administration on the damaged organ is essential in preventing cellular damage and death. This study aimed to learn about the effect of hADSC administration on an ischemia-reperfusion injury. MATERIAL AND METHODS: A total of 22 Wistar rats divided into 5 groups, two groups each consist of 5 male Wistar rats with testicular torsion model without hADSC therapy (group I), while 2 other groups consist of 5 rats with testicular torsion model were given 1.0×106 cells intratesticular hADSC injection 30 minutes after testicular detorsion (group II). Both groups were euthanized at 1 and 4 weeks of observation. The last group consists of 2 rats without any treatment or model (negative control group). Following euthanasia, testicular tissue was harvested for MDA expression measurement using ELISA and histopathological examination. Statistical analysis using an one way ANOVA was done with SPSS version 21.0. RESULTS: The result of MDA examination using the ELISA method has shown a concentration difference between group I (control) and group II (hADSC treatment). Testicular MDA concentration in the treatment group was significantly lower on the 1st and 4th week of observation (p2=0.000, p4=0.016). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.972). On histopathological examination, Johnsen score in the treatment group was significantly higher on the 4th week of observation (p=0.044). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.195). CONCLUSION: Intratesticular hADSC administration can inhibit ROS formation due to ischemia-reperfusion injury in testicular tissue after testicular detorsion in Wistar rats.
