Disposable digital (dd-)FURS has been developed to overcome limitations such as durability, degradation, and repair cost of reusable scopes. The diameter of commercially-available models ranges from 7.

Identification of mitophagy-related gene signatures for predicting delayed graft function and renal allograft loss post-kidney transplantation.

Background: Ischemia-reperfusion injury (IRI) is an unavoidable consequence post-kidney transplantation, which inevitably leads to kidney damage. Numerous studies have demonstrated that mitophagy is implicated in human cancers. However, the function of mitophagy in kidney transplantation remains poorly understood.

Embryonal rhabdomyosarcoma of prostate combined with prostatic abscess in an adult patient: a case report and literature review.

Background: Embryonal rhabdomyosarcoma (ERMS) of the prostate is a rare and aggressive malignant tumor in adults with a poor prognosis in general. The main presenting symptoms are dysuria and acute urinary retention. Prostate ERMS is easily misdiagnosed, which leads to delays in treatment.

Postoperative Renal Abscess Following Tip-Flexible Suctioning Ureteral Access Sheath and Digital Ureteroscopic Lithotripsy: A Case Report.

BACKGROUND The tip-flexible suctioning ureteral access sheath (TFS-UAS) can be bent under flexible ureteroscopes, which facilitates removal of renal stone segments by irrigation and suctioning effects. Small-scale comparative studies found it safer and more efficacious than traditional UAS. However, complications such as renal abscess were not documented after TFS-UAS combined with digital FURS.

Preliminary experience with lost mini percutaneous nephrostomy channel retrieval by methylene blue injection.

Percutaneous nephrolithotomy (PCNL) is the primary choice for managing large renal stones and the establishment of mini-/micro-channels has been increasingly gaining practice. The smaller the channel, the easier it is to be lost, which may require a new puncture site and increase the risk of bleeding complications. In this study, we retrospectively reviewed 1,056 PCNL procedures in our single institute, The University of Hong Kong - Shenzhen Hospital, between March 2014 and August 2023.

Left endoscopic combined intrarenal surgery with electrocoagulation hemostasis and right flexible ureteroscopic lithotripsy for bilateral upper urinary tract stones: a case report.

Background: Percutaneous nephrolithotomy (PCNL) is the first-line treatment for large renal stones. However, multi-tract or staged procedures may be necessitated in bilateral or anatomically-complex stones to achieve stone clearance. Endoscopic combined intrarenal surgery (ECIRS) integrates the advantages of PCNL and retrograde intrarenal surgery.

A non-invasive 25-Gene PLNM-Score urine test for detection of prostate cancer pelvic lymph node metastasis.

Background: Prostate cancer patients with pelvic lymph node metastasis (PLNM) have poor prognosis. Based on EAU guidelines, patients with >5% risk of PLNM by nomograms often receive pelvic lymph node dissection (PLND) during prostatectomy. However, nomograms have limited accuracy, so large numbers of false positive patients receive unnecessary surgery with potentially serious side effects.

Incidental Finding of Intrarenal Foreign Guidewire During Percutaneous Nephrolithotomy: A Case Report and Literature Review.

BACKGROUND Percutaneous nephrolithotomy (PCNL) is indicated for large renal calculi (≥2 cm) and is often the treatment of choice due to its high success rate. Guidewire fragmentation is a rare procedural accident that can occur in PCNL but may be missed. Retention of the fragment within the upper urinary tract can lead to further complications, such as recurrent nephrolithiasis or impairment of renal function.

Punicalagin protects against impaired skeletal muscle function in high-fat-diet-induced obese mice by regulating TET2.

The function of skeletal muscles can be markedly hampered by obesity. Ten-eleven translocation 2 (TET2) is an important therapeutic target for ameliorating skeletal muscle dysfunction. Our previous study revealed that punicalagin (PUN) regulated TET2 in obese mice; however, whether PUN can prevent obesity-induced skeletal muscle dysfunction by regulating TET2 remains unclear.
