Ureteric Calculus in a Left Complete Duplex System Masquerading as an Impacted Stone: A Case Report and Literature Review.

Ureteric calculi are common urological problems. However, the management of stone disease varies considerably with patient choice and anatomy. There are few reports about ureteral calculi in patients with unilateral complete duplex kidneys managed by ureteroscopy.

Tubeless mini-percutaneous nephrolithotomy for renal stones larger than 20 mm.

Introduction: The aim of this study is to evaluate the outcomes of tubeless mini- percutaneous nephrolithotomy (PCNL) for the treatment of large (>20 mm) renal stones.

Patients And Methods: This study included consecutive patients who underwent single-session tubeless mini-PCNL (tract size 16-20 F) for large (>20 mm) renal stones. Stone-free status meant complete clearance or residual fragments <4 mm.

Role of conservative management of stones.

Urinary tract stone disease is one of the most common pathologies of the modern era with a rising prevalence owing to incidentally detected renal stones from imaging for other reasons. Although there is consensus on active management of symptomatic and asymptomatic stones in high-risk patient groups, conservative management of stones is still controversial. We have reviewed the literature pertaining to conservative management of 3 groups of stones-asymptomatic calyceal stones, staghorn stones, and ureteric stones-and summarized the findings to provide guidance in the conservative management of stones.

Safety and efficacy of a single middle calyx access (MCA) in mini-PCNL.

To compare outcomes of a single middle calyx access (MCA) with a single upper or lower calyceal access in mini-PCNL. From May 2015 through August 2018, patients' files who underwent a single renal access mini-PCNL were retrospectively reviewed. All patients underwent fluoroscopic-guided access (16-20 F) in the prone position.

Long-Term Prospective Outcomes of Patients with Non-Muscle Invasive Bladder Cancer After Holmium Laser Ablation.

To evaluate the long-term tumor recurrence, progression, and cancer-specific mortality (CSM) of patients after holmium laser ablation of non-muscle invasive bladder cancer (NMIBC) under topical anesthesia. To identify variables that help to predict risk of tumor recurrence, progression, and CSM. A prospective study of 251 consecutive patients with 399 recurrent NMIBC who underwent outpatient Holmium yttrium aluminium garnet laser ablation under topical anesthesia was carried out between September 2006 and September 2018.

The natural history of asymptomatic calyceal stones.

Objectives: To evaluate the outcomes of patients with incidentally detected asymptomatic calyceal stones on active surveillance, and to identify risk factors for stone-related adverse events (AEs).

Patients And Methods: In this retrospective case series, we identified all renal units with non-contrast computed tomography diagnosed asymptomatic calyceal stones in a single reference centre between August 2005 and August 2016. Primary endpoints were spontaneous stone passage and need for stone-related surgical intervention.

Atrophy of the tongue as the presenting feature of metastatic prostate cancer.

Prostate cancer is the most frequently diagnosed solid organ cancer in men and is the second leading cause of cancer-related deaths in men in the United Kingdom. Commonly, it metastasizes to bones and lymph nodes, however, in advanced hormonerefractory disease it may involve the skull base leading to associated cranial nerve palsies. Cranial nerve palsy as the presenting feature of advanced hormone-sensitive prostate cancer is extremely rare.

Synchronous and metachronous ureteric metastases from adenocarcinoma of the colon.

Primary adenocarcinoma of the ureter occurs in only <1%. Furthermore, metastatic carcinoma to the ureter is very rare and has been described to occur from breast, lung, stomach and prostate cancers. However, metastases to the ureter from colon cancers are extremely rare, and have been largely reported as incidental post-mortem cases.
