Urologic tumors make up approximately 10% of all pediatric cancers, and include a variety of different histologies and imaging considerations. In this review, we discuss standard radiologic approaches for children with tumors arising in the genitourinary system, and identify important ways in which imaging affects the differential diagnosis, preoperative planning, and staging of these tumors. In addition, we provide an update on strategies to reduce the time of imaging, which may obviate the need for sedation in younger patients. Efforts to reduce a patient's overall radiation exposure and subsequent risk of second malignancy are also detailed, including recent work on surveillance imaging following completion of therapy. Finally, we highlight new techniques such as radiomics that are now being investigated for patients with these malignancies.Several hereditary cancer predisposition syndromes are associated with genitourinary (GU) manifestations in children. The GU manifestation may be the first symptom of a more global syndrome to arise, which places the pediatric urologist in a unique position to impact the health of the child. Some GU manifestations are pathognomonic for a particular hereditary cancer predisposition syndrome, which can prompt genetic testing and enhanced surveillance for other features of the condition. In other cases, knowledge of an underlying hereditary cancer predisposition syndrome alters treatment decisions. This review focuses on hereditary cancer predisposition syndromes that impact the GU tract and are likely to be seen by a pediatric urologist.Diagnosis of HIV infection and AIDS need to rely on HIV antibody or HIV antigen test internationally, and the test process is divided into preliminary screening test and confirmatory test. The HIV/AIDS screening laboratory of the First Affiliated Hospital of Nanjing Medical University has been using electrochemiluminescence (ECL) to screen the patients. A 50-year-old man with his enhanced computed tomography (CT) scan revealing two soft tissue density images were seen in the left kidney came to the hospital for medical treatment. The patient's postoperative pathological examination revealed (left kidney) renal clear cell carcinoma. The HIV screening tests of the patient several times in perioperative period showed reactivity, but the result of the confirmatory tests of Nanjing Municipal Center for Disease Control and Prevention were negative all the time. False positive HIV results are quite rare in the setting of renal clear cell carcinoma. There must be some substances that can react with the HIV Combi PT designed to detect anti-HIV antibodies of the IgG- and IgM-class as well as HIV p24 antigen in this patient. In conclusion, false positive results of HIV screening test may occur in serum of patients with renal cell carcinoma, and necessary confirmatory tests are needed. When clinicians encounter such problems, confirmatory tests should be conducted according to the guidelines to avoid misdiagnosis.Wilms' tumor is the most common primary renal malignancy in children (80%) and the less common tumors include renal cell carcinoma, rhabdoid tumor, clear cell sarcoma, cellular congenital mesoblastic nephroma and medullary carcinoma, all of which originate from renal parenchyma. The tumors originating from renal pelvis are rare. The immunohistochemistry (IHC) showed INI1 deletion with the WT1 positive which has not been reported as we know. A 3-year-old boy was admitted to hospital for vomiting. An ultrasonography examination revealed a mass in the right kidney, medium echo, as well as hydronephrosis with collecting system separation of 3.5 cm. The computed tomography and the magnetic resonance (MR) radical showed that the tumor occupied the right renal pelvis and extended into the ureter. A radical nephroureterectomy was accomplished through a transabdominal approach. The pathologic diagnosis was malignant renal tumor with INI1 deficiency which was atypical in morphology and immunophenotype, but according to immunophenotype renal rhabdomyoid tumor could not be excluded. The patient was treated with carboplatin, etoposide and cyclophosphamide chemotherapy for 6 months. Follow-up studies of the patient showed no indication of recurrence or metastasis 22 months after nephrectomy. selleck kinase inhibitor The novel findings may expand the spectrum of pediatric renal tumors to include the special malignancy.Retrograde ejaculation contributes to male infertility. Pharmacotherapy has a limited role in retrograde ejaculation. Deflux, a viscous substance, consists of two components dextranomer microspheres and stabilized hyaluronic acid for the treatment of children with vesicoureteral reflux. According to the published articles, the authors described the first case achieved not only restoration of antegrade ejaculation but also followed conception of the spouse after transurethral bladder neck injection of Deflux. A 30-year-old male kept infertile after 3 years of marriage. The patient reported that he could not ejaculate in an antegrade direction after puberty when he reached sexual climax. There was no semen expulsed from the urethral meatus. Medicine prescribed by a local hospital didn't restore normal ejaculation. Four embryos fertilized by intracytoplasmic sperm injection developed well until transplantation, but none survived. The local reproductive center confirmed that his spouse preserved full capacity of fertility. He was diagnosed as retrograde ejaculation by real-time monitoring of transrectal ultrasound. He received transurethral bladder neck injection of Deflux. One month later, the patient restored antegrade ejaculation and the spouse of the patient conceived. During 18 months of follow-up, no related complications of the surgery have been observed. Transurethral bladder neck injection of Deflux can be considered as an alternative treatment method for retrograde ejaculation, and natural conception is possible thereafter.Our aim is to assess the efficacy of prophylactic ureteral catheter placement on patients undergoing laparoscopic gynecological surgery. We searched the electronic database including PubMed, Cochrane Library, Embase, Web of Science, WANFANG and CNKI in January 2020 to identify possible studies without languages limitations. A manual search was also conducted. The trials that compared catheterized group (CG) to non-catheterized group (NCG) were included. This meta-analysis was accomplished by RevMan5 (version 5.3). Initial search yield 997 studies and 5 randomized control trials were included in the final meta-analysis. Pooling data of five studies showed that patients in the CG had a lower risk of ureteral injury than those in NCG (RR 0.44, 95% CI 0.20-0.97, P=0.04) without significant between-study heterogeneity (P=0.23, I2=29%). The pooled data analysis showed a statistically significant difference in favor of prophylactic ureter catheter placement (MD -40.51, 95% CI -58.65 to -22.36, P less then 0.0001). Random-effects model meta-analysis found that patients in the CG experienced higher EBL compared to NCG (SMD -5.
