Value of artificial intelligence model based on unenhanced computed tomography of urinary tract for preoperative prediction of calcium oxalate monohydrate stones .

Background: Urolithiasis is a global disease with a high incidence and recurrence rate, and stone composition is closely related to the choice of treatment and preventive measures. Calcium oxalate monohydrate (COM) is the most common in clinical practice, which is hard and difficult to fragment. Preoperative identification of its components and selection of effective surgical methods can reduce the risk of patients having a second operation.

Virtual or real: lifelike cinematic rendering of adrenal tumors.

The adrenal gland is small in size and hidden in location. Adrenal tumors are relatively difficult to diagnose due to the wide variety of tumors and partial overlap of image features. Cinematic rendering (CR) is a novel, three-dimensional post-processing technology that simulates how light propagates in the real world, providing high-resolution visualizations that truly present subtle anatomical details.

Prostatic anatomical parameters correlate with clinical characteristics suggestive of benign prostatic hyperplasia.

We conducted the present study to assess the correlation of the prostatic anatomical parameters, especially the ratio of peripheral zone thickness and transitional zone thickness, with clinical and uroflowmetry characteristics suggestive of benign prostate hyperplasia (BPH). A total of 468 consecutive patients with a detailed medical history were identified. All patients were evaluated by scoring subjective symptoms with the International Prostate Symptom Score (IPSS) and quality of life (QoL).

Combination of polyethylene glycol impregnation and paraffin heat treatment to protect round bamboo from cracking.

Round bamboo has drawn more and more attention in architecture, decoration and recreational products. Splitting brings some safety problems, which shorten the service life of round bamboo. In this paper, three schemes were adopted as follows to solve the problem: round bamboo was impregnated in polyethylene glycol (PEG)-1000 solution alone, heat treatment in paraffin alone or treated with the combination of PEG impregnation and paraffin heat treatment (PEG-PH).

Comparison of Yang-Monti ileal ureter-bladder anastomosis versus Yang-Monti ileal ureter-ureteral anastomosis for the treatment of ureteral stenosis: a randomized controlled trial in a miniature pig model.

Background: The aim of the present study was to establish an animal model of Yang-Monti ileal ureter-bladder anastomosis and Yang-Monti ileal ureter-ureteral anastomosis and compare the advantages and disadvantages of the two surgical methods.

Methods: Fourteen 12-month-old male Chinese miniature pigs weighing 21 ± 1.38 kg were randomly divided into two groups.

Prostatic epithelial cells and their high expressions of CKIP-1 affect the TGF-β expression levels which might reduce the scar formation in remodeling stage at prostatic urethral wounds after wound repair.

Objective: There are less scar formations in some wounds after wound repair. Our earlier study had shown that the amount of collagen fibers in canine prostatic urethra wound were less than in bladder neck wound after 2-μm laser resection of the prostate (TmLRP) and partial bladder neck mucosa at 4 weeks. The purpose of this study was to observe the amount of scar tissue and characterize the probable causes of "less scar healing" in prostatic urethra wound.

Initial prospective study of ambulatory mPCNL on upper urinary tract calculi.

Objective: To explore the feasibility and safety of ambulatory mPCNL (mini percutaneous nephrolithotomy) on upper urinary tract calculi.

Methods: Clinical data of 18 patients received ambulatory mPCNL during Aug. 2017 to Jan.

Treatment of urinary calculi after Yang-Monti ileal ureter reconstruction: a case report.

Background: The development of ureteral calculi after Yang-Monti ileal ureter reconstruction has not been reported. This study was performed to explore the safety and effectiveness of ureteroscopy combined with laser lithotripsy in the treatment of ipsilateral lower ureteral calculi and lower calyceal calculi after Yang-Monti ileal ureter reconstruction.

Case Presentation: A 48-year-old man was admitted to our hospital with ipsilateral distal ureteral calculi and ipsilateral lower calyceal calculi.

Urine can speed up the re-epithelialization process of prostatic urethra wounds by promoting the proliferation and migration of prostate epithelial cells.

Objectives: The present study aimed to investigate the influence of urine on re-epithelialization in canine prostatic urethra after prostatectomy and explore possible causes.

Method: We established two groups of prostatic canine models. The first group contained urine that canines underwent the surgery by two-micron laser resection of the prostate-tangerine technique (TmLRP-TT), and no transurethral catheter was required.

Re-epithelialization resulted from prostate basal cells in canine prostatic urethra may represent the ideal healing method after two-micron laser resection of the prostate.

The purpose of this study is to characterize the re-epithelialization of wound healing in canine prostatic urethra and to evaluate the effect of this re-epithelialization way after two-micron laser resection of the prostate (TmLRP). TmLRP and partial bladder neck mucosa were performed in 15 healthy adult male crossbred canines. Wound specimens were harvested at 3 days, and 1, 2, 3, and 4 weeks after operation, respectively.

[In vitro studies of 2 µm laser treatment of benign prostatic hyperplasia].

Objective: To compare the speed of vaporization of human prostatic tissue with benign prostatic hyperplasia (BPH) and depth of tissue damage using 70 and 120 W 2 µm laser devices.

Methods: Fresh prostatic tissue specimens were obtained from 5 patients by open prostatectomy and divided into separate groups (70 and 120 W) based on the energy of laser output (70 and 120 W respectively). Trials were performed in acryl basin containing 0.

[New understanding of dog's prostatic urethral re-epithelial underwent two-micron laser prostatic vaporesection].

Objective: To study the re-epithelialization of dog's prostate urethra after two-micron laser resection of the prostate (TmLRP) and the role of CK34 (CK34βE12)-positive cells in this process.

Methods: TmLRP were performed in 15 elder male dogs and wound specimens harvested at Days 3, 7 and 14 respectively. Immunohistochemical staining was performed to determine the expression levels of CK34 and prostate specific antigen (PSA) in prostatic urethra urothelial cells.
