Utilizing artificial neural network system to predict the residual valve after endoscopic posterior urethral valve ablation.

Purpose: To build, train, and assess the artificial neural network (ANN) system in estimating the residual valve rate after endoscopic valve ablation and compare the data obtained with conventional analysis.

Methods: In a retrospective cross-sectional study between June 2010 and December 2020, 144 children with a history of posterior urethral valve (PUV) who underwent endoscopic valve ablation were enrolled in the study. MATLAB software was used to design and train the network in a feed-forward backpropagation error adjustment scheme.

Has the COVID-19 pandemic affected ureteral stone management in pregnant women? A retrospective single-center study.

Introduction: This study aimed to evaluate the effect of coronavirus disease (COVID-19) on the patients' referral in the pregnant population and also investigate each treatment approach's advantages and disadvantages for acute renal colic in pregnancy.

Methods: In this retrospective study, we included all pregnant women with ureteral stones referred to a referral center between January 2019 and March 2021.

Results: Among 53 pregnant women, 18 (33.

Reference value of testicular temperature measured by finite element analysis after first staged inguinal orchidopexy in children with abdominal testis and short spermatic cord.

Purpose: This study aims to build a 3D reconstruction computed simulation model and to establish a regression equation for detecting the testis's temperature by its location after first staged open orchidopexy in children with abdominal undescended testis (UDT) and short spermatic cords.

Methods: In this cross-sectional study, we enrolled 31 children with abdominal UDT and short spermatic cords who underwent first staged orchiopexy between 2017 and 2020. Using ultrasonography to obtain the testis's location distance from the skin surface (X1), external iliac vessel (X2), and internal inguinal ring (X3), we input the data into a 3D reconstruction computed simulation along with COMSOL to calculate the testicular temperature.

Distal ureteral calculi in a patient with ileal conduit and urinary diversion treated via antegrade ureteroscopic lithotripsy: A case report.

Ureteral calculi management in patients with urinary diversion is challenging for most urologists. The surgeon should consider the patient's diversion type, BMI, stone size and location, and his/her experience with the procedure. We report an 85-year-old ileal conduit diversion man presented with ureteral calculi and treated via antegrade ureteroscopic lithotripsy.

Hydatid Disease of the Liver Presenting as Spontaneous Cutaneous Fistula: A case report.

Hydatid cyst (HC) disease is a parasitic infection produced by cysts containing the larval phase. Patients with HC disease are typically asymptomatic until incidentally diagnosed or when complications occur. A rare presentation of liver HC is spontaneous cutaneous fistualisation.

Repair of total penile skin loss after ritual circumcision using a scrotal flap: a case report.

Ritual circumcision is associated with a high rate of complications, mainly if performed by an untrained practitioner. Furthermore, excessive skin removal is a rare complication of this procedure that results in penis "trapping" underneath the skin and future sexual dysfunction. Here, we presented a 45-day-old Yemeni newborn with a trapped penis due to total loss of penile skin during a ritual circumcision performed by a traditional untrained practitioner using the guillotine technique one month ago.

Giant asymptomatic left renal oncocytoma in a 40-year-old man: a case report.

Renal oncocytoma is a benign tumor that arises from epithelial cells of the distal renal tubules. It is naturally presented with a small-sized mass, and giant oncocytoma is uncommon. Renal oncocytoma is frequently asymptomatic and challenging to distinguish preoperatively from renal cell carcinoma (RCC).

Pentalogy of Cantrell Associated with Ectopia Cordis: A Case Report.

Pentalogy of Cantrell is a congenital anomaly of the median mesodermal constructions with a poor prognosis. It is characterized by defects of the anterior diaphragm, the lower sternum, the abdominal wall, pericardium, and various congenital heart malformations. We present a case of ectopia cordis and Pentalogy of Cantrell in a newborn of a healthy 35-year-old woman with no history of embryotoxic exposure or smoking.

Sarcomatoid variant of urothelial carcinoma in the renal pelvis with brain metastasis: a case report.

Sarcomatoid urothelial carcinoma (UC) of the renal pelvis is rare. It is a high-grade malignant tumor that contains both epithelial and mesenchymal elements. Brain metastases from renal pelvis UC are infrequent and represented in few cases.

Is there any Sympathetic Skin Response Abnormality in Raynaud Phenomenon?

Objectives: This study aimed to evaluate sympathetic skin response (SSR) among patients with Raynaud phenomenon (RP). SSR is a technique for assessment of the damage of peripheral neuropathies and the disorders of the sympathetic system.

Methods: Between January 2015 and December 2018, approximately 20 patients with RP and 20 healthy subjects (control group) were recruited from patients referred to the outpatient clinics of Shiraz University of Medical Sciences, Shiraz, Iran.

Totally ultrasound-guided minimally invasive percutaneous nephrolithotomy in children: Is it safe?

Objective: The objective of the study was to assess the outcome and feasibility of ultrasonography (US)-guided minimally invasive percutaneous nephrolithotomy (mini-PCNL) in children.

Materials And Methods: Twenty-five children with upper urinary tract stones who had undergone US-guided mini-PCNL from June 2017 to June 2020 were enrolled in this study. Patients' demographic information and post-treatment results were retrospectively gathered and analysed.

Minimal invasive percutaneous nephrolithotomy (Mini-PCNL) in children: Ultrasound versus fluoroscopic guidance.

Background: Miniaturization of endoscopic instruments in percutaneous nephrolithotomy (PCNL) allowed less invasive procedures with low complication rates, especially in children. This study was conducted to evaluate the safety and efficacy of ultrasonography-guided (USG) versus fluoroscopy-guided (FG) mini-PCNL in children.

Materials And Methods: This is a retrospective comparative study conducted from June 2015 to June 2020.

Use of anterolateral thigh flap for reconstruction of traumatic bilateral hemipelvectomy after major pelvic trauma: a case report.

Background: Major pelvic trauma (MPT) with traumatic hemipelvectomy (THP) is rare, but it is a catastrophic health problem caused by high-energy injury leading to separation of the lower extremity from the axial skeleton, which is associated with a high incidence of intra-abdominal and multi-systemic injuries. THP is generally performed as a lifesaving protocol to return the patient to an active life.

Case Report: A 12-year male patient exposed to major pelvic trauma with bilateral THP survived the trauma and multiple lifesaving operations.
