Machine Learning Models for Predicting Stone-Free Status after Shockwave Lithotripsy: A Systematic Review and Meta-Analysis

Wed, 04/21/2021 - 00:00
We performed a systematic review and meta-analysis to investigate the use of machine learning techniques for predicting stone-free rates following Shockwave Lithotripsy (SWL). Eight papers (3264 patients) were included. Two studies used decision-tree approaches, five studies utilised Artificial Neural Networks (ANN), and one study combined a variety of approaches. The summary true positive rate was 79%, summary false positive rate was 14%, and Receiver Operator Characteristic (ROC) was 0.90 for machine learning approaches.

Safety and Outcomes of using ureteric access sheath (UAS) for treatment of Paediatric renal stones: Outcomes from 2 tertiary endourology centres

Tue, 04/20/2021 - 00:00
To look at the safety and outcomes of using ureteral access sheath (UAS) for paediatric renal stones. The use of UAS is variable in urological practice with very little clinical work on their use in paediatric kidney stone disease.

Oncocytic Papillary Renal Cell Carcinoma in an 11-year-old girl

Tue, 04/20/2021 - 00:00
Oncocytic Papillary Renal Cell Carcinoma (OPRCC) is a rare variant of renal cell carcinoma with overlapping characteristics type 1 and 2 of papillary renal carcinoma. Based on the literature, OPRCC is predominantly present in adult males. OPRCC has a specific genetic affiliation with the Fumarate Hydratase gene requiring all patients diagnosed with OPRCC to undergo genetic testing. There isn't any agreement for the treatment of OPRCC due to the rarity of the disease; however, a radical nephrectomy poses as a possible modality.

Triple retroaortic renal vein with tumor thrombus

Tue, 04/20/2021 - 00:00
A case report of a 51-year-old man with left renal tumor and level II vena cava tumor thrombus (thrombus extending >2 cm above the renal vein, but below the hepatic veins) in a rare anatomical variant of renal vein. In nonmetastatic patients, aggressive surgical resection is widely accepted as the standard management option, but some doubts about the best practice in these patients are relevant. Surgical approach on those patients is a challenge for the surgeons, and anatomical variants make the procedure even more difficulty.

Successful Fowler-Stephens orchiopexy for an abdominal testis associated with continuous type of splenogondal fusion: A case report

Thu, 04/15/2021 - 00:00
Splenogonadal fusion (SGF) is a rare congenital anomaly in which there is abnormal adhesion between splenic tissue and gonads. Several patients with cryptorchidism associated with this anomaly have undergone orchiectomy because of the suspicion of tumors. Preoperative computed tomography (CT) is useful in differentiating between SGF and tumors, and in evaluating the vasculature of the SGF. We report a boy with an abdominal testis associated with SGF. Based on the CT findings, we successfully performed Fowler-Stephens orchiopexy.

SUPERNUMERARY TESTIS DISCOVERED UPON WORKUP OF A PARATESTICULAR MASS

Wed, 04/14/2021 - 00:00
A supernumerary testis is a rare finding with limited description in the literature. Presentations of supernumerary testes vary and often involve initial discovery intraoperatively or in association with a separate condition. In this case report, we describe our experience of a patient with ultrasound imaging concerning for a left paratesticular mass. The patient was taken to the operating room where the mass was found to be an atrophic, supernumerary testis. We also address the specific anatomy encountered in our case and discuss both the intraoperative and post-operative management that resulted, in addition to reviewing relevant literature.

Local and Regional Recurrences of Clinically Localized Renal Cell Carcinoma after Nephrectomy: A 15 Year Institutional Experience with Prognostic Features and Oncologic Outcomes

Wed, 04/14/2021 - 00:00
To evaluate outcomes for patients with local recurrence (LR) of clinically localized renal cell carcinoma (RCC) without concurrent systemic metastasis from our institution, an event that occurs rarely (1-3%) after surgery. LR may be a harbinger of poor outcomes, and the best management of these patients is unclear.

Robot-assisted Modified One-Stage Orchiopexy: Description of a Surgical Technique

Wed, 04/14/2021 - 00:00
In recent years, robot-assisted laparoscopic procedures have gradually replaced standard laparoscopic procedures in the realm of pediatric urology. The potential advantages of the robot-assisted technique include a higher degree of dexterity, three-dimensional visualization and reproducibility. Although laparoscopic orchiopexy is considered to be the gold standard approach in cases of intra-abdominal testes, it can be technically challenging. A crucial point in decision-making is choosing between preservation of testicular blood vessels or sacrificing the vessels in order to achieve sufficient length, as with the one and two-stage Fowler-Stephens orchiopexy (FSO).

Melanotic neuroectodermal tumor of infancy in the epididymis: a rare and considerable cause of scrotal mass

Wed, 04/14/2021 - 00:00
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, benign neoplasm with a predilection for children that predominantly involves the craniofacial region. Here we report two cases of MNTI involving epididymis, placing emphasis on the sonographic features. Both appeared to be hypoechoic, regular shaped masses with abundant blood supplies. The unique sonographic features and age of predilection make it possible to diagnose MNTI within the scrotum by ultrasonography.

Clinical characterization of radiation-associated muscle-invasive bladder cancer

Sun, 04/11/2021 - 00:00
To characterize the presentation, patterns of care, and outcomes of radiation-associated muscle-invasive bladder cancer (RA-MIBC) compared to primary (non-radiation associated) MIBC. RA-MIBC has been suggested to represent a more aggressive disease variant and be more difficult to treat compared to primary (non-radiation associated) MIBC.
