Purpose: To maintain safe intrarenal pelvic pressure (IPP), the combination of flexible ureteroscope (fURS) and traditional ureteral access sheath (T-UAS) should maintain a basic rule that is the ratio of endoscope-sheath diameter (RESD) ≤ 0.75. However, the negative-pressure ureteral access sheath (NP-UAS) may break the rule of negative pressure suction.

Methods: Thirty-one consecutive patients with continuous renal hemorrhage after mini-PCNL were enrolled from January 2015 to January 2022. Demographic and clinical data were retrospectively recorded and analyzed.
Article Synopsis
- An 86-year-old man had a Foley catheter put in but it ended up in the wrong place, his ureter, causing him pain.
- The doctors tried different methods to fix it, like cutting the catheter, but nothing worked until they used a special needle to puncture the balloon and remove the catheter.
- This is the first time a Foley catheter was successfully taken out of the ureter using this method, and it highlights that doctors may need to try different approaches when things go wrong.
Background: Acute pulmonary embolism and severe renal bleeding are two lethal postoperative complications, but there has been no report that involves both of them after mini-percutaneous nephrolithotomy.
Case Presentation: A 62-year-old woman was admitted to our hospital with extremely severe hydronephrosis and multiple right renal calculi. After thorough examination, she received prone-position mini-percutaneous nephrolithotomy under spinal anaesthesia.
Objective: To compare surgical characteristics, clinical efficacy, and complications of plasmakinetic enucleation of the prostate (PKEP) and transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).
Materials And Methods: From January 2015 to May 2018, 370 patients underwent TURP were included into the TURP group. Meanwhile, another 370 patients underwent PKEP (matched by age, prostate volume, and duration of BPH) were included into the PKEP group.
Background: Lingual nerve injury (LNI) is a rare complication following the use of laryngeal mask airway (LMA). The occurrence of this unexpected complication causes uncomfortable symptoms in patients and worsens their quality of life. We present an unusual case of LNI caused by the use of an LMA in percutaneous nephrolithotomy (PCNL).

Case Presentation: An 83-year-old man was admitted to our hospital complaining about intermittent left flank pain that had persisted for 1 week.
Background: Hernia mesh erosion into the urinary bladder is a rare complication of hernioplasty, and mesh immigration is the most probable pathophysiology. There is no report describing mesh erosion induced by fixing tacks in inguinal hernia repair.
Case Presentation: A 37-year-old man was admitted to our hospital with frequency, urgency and odynuria for 3 months.
Purpose: To clarify appropriate combinations of flexible ureteroscope (FURS) and ureteral access sheath (UAS), which can maintain a low intrapelvic pressure (IPP) during FURS with lasertripsy.
Methods: Four kinds of FURSs (Polyscope, Olympus URF-P6, Stroz Flex-X, and Olympus URF-V) and six sizes of UASs (11/13F × 36 cm, 11/13F × 46 cm, 12/14F × 36 cm, 12/14F × 46 cm, 13/15F × 36 cm, and 13/15F × 46 cm) were tested. A novel gas-liquid-pressure-control system (GLPCS) was used to maintain a stable and adjustable irrigation pressure form 50-500 cmHO.
