    Abstract 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. 2018 and 23 patients treated with routine inpatient mPCNL of the corresponding period were collected. All the patients included received 16Fr channel PCNL under the guidance of Doppler ultrasound. A 6Fr double J stent was placed in the ureter for internal drainage, and either an indwelling 14Fr open nephrostomy tube was placed or the puncture channel was filled with absorbable hemostatic materials alone, depends on the bleeding condition of the puncture channel and the intraoperative conditions. Preoperative parameters and surgery time, complications, total hospitalization costs and hospital stay time between the two groups were compared.
    Results: Preoperative parameters regarding age (P=0.057), sex distribution (P=0.380), ASA score (P=0.388), Calculi CT value (P=0.697), and the S.T.O.N.E. score (P=0.122) were comparable between the two groups. Maximum diameter of calculi (cm) of the conventional hospitalization group, however, was larger than the ambulatory surgery group (P=0.041). There were no significant differences in the mean surgery time (P=0.146), postoperative hemoglobin drop (P=0.865), Calculi-free rate on the next day after surgery (P=0.083) and postoperative fever rate (P=0.200) between the two groups. With regard to tubeless rate (P<0.001), total hospitalization costs (P=0.003) and hospital stay time (P<0.001), there were significant advantage favored ambulatory mPCNL.
    Conclusions: For patients with simple upper urinary tract calculi and relatively good performance status, ambulatory mPCNL is feasible as it's equally safe and efficient as compared with routine inpatient mPCNL. Moreover, ambulatory mPCNL decreases hospitalization costs and hospital stay time. Nevertheless, perioperative management should be carefully conducted, and well-designed studies are warranted.

    Abstract 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. We retrospectively collected a series of pathologically confirmed adrenal tumor cases, raw data was introduced into the post-processing workstation, and different tools and templates of CR software were used for reconstruction and rendering. Compared with traditional black and white two-dimensional images and three-dimensional volume rendering (VR) images, CR images were more colorful, layered, and closer to the truth. CR has potential in diagnosing and preoperative planning of adrenal tumors, allowing vivid and realistic visualization of tumor location, morphology, different components (solid, cystic, fat, calcification, etc.), the pattern of enhancement, and the relationship with surrounding tissues and organs.

    Abstract 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. One year prior to this admission, the patient had undergone Yang-Monti ileal ureter reconstruction due to long-segment ureteral stenosis. After conservative treatment failed, we used a rigid ureteroscope with a holmium laser to break up the distal ureteral calculi, and successfully removed the renal calculi with a digital flexible ureteroscope and basket extractor.
    Conclusion: The successful outcome of the present case suggests that ureteroscopy combined with laser lithotripsy is a valuable option for the management of urinary calculi following Yang-Monti ileal ureter reconstruction.

    Abstract 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. Methods that can be used for stone composition analysis include infrared spectroscopy, X-ray diffraction, and polarized light microscopy, but they are all performed on stone specimens
    Methods: Preoperative unenhanced CT images of patients with urinary calculi whose components were determined by infrared spectroscopy in a single center were retrospectively analyzed, including 337 cases of COM stones and 170 of non-COM stones. All images were manually segmented and the image features were extracted, and randomly divided into the training and testing sets in a ratio of 7:3. The least absolute shrinkage and selection operation algorithm (LASSO) was used to construct the AI model, and classification of the training and testing sets was carried out.
    Results: A total of 1,218 radiomics imaging features were extracted, and 8 features with non-zero coefficients were finally obtained. The sensitivity, specificity and accuracy of the AI model were 90.5%, 84.3% and 88.5% for the training set, and 90.1%, 84.3% and 88.3% for the testing set. The area under the curve was 0.935 for the training set and 0.933 for the testing set.
    Conclusions: The AI model based on unenhanced CT images of the urinary tract can predict COM and non-COM stones

    Abstract 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.
    Methods: A total of 12 healthy adult male crossbred canines underwent resection of prostate and partial bladder neck mucosa using 2-μm laser. The prostatic urethra and bladder neck wound specimens were harvested at 3, 4, 8 and 12 weeks after operation, respectively. The histopathologic characteristics were observed by hematoxylin and eosin(HE)staining, and the expression of transforming growth factor-β
    Results: The histology showed that there were a large number of prostatic epithelium and a small amount of scar tissue in prostatic urethra wound, while no epithelial cells and more scar tissue in bladder neck wound at 4, 8 and 12 weeks after repair. There were a higher expression level of TGF-β
    Conclusions: A large number of prostate epithelial cells in prostatic urethra wound may be one of the causes of less formation of scar tissue after repair. The prostate epithelial cells might reduce expression level of TGF-β

    Abstract 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. The second group was without urine that canines accepted the surgery by TmLRP-TT add ureter skin ostomy urine bypass. Histopathology of re-epithelialization of repair in trauma in canine prostatic urethra was observed by hematoxylin and eosin (HE) staining, and immunochemistry was used to determine the expression of transforming growth factor-β
    Results: The histology displayed that there was distinct proliferation of prostatic cell under the wound after 3 days, re-epithelialization began after 9 days, and finished after 28 days at urine group. The TGF-β1 like-IR in prostatic epithelium cells and fibroblast cells under the wound at urine group were strikingly increased as compared with the cells at no urine group after 3, 9, and 11 days, respectively (p < 0.05). In CCK-8 and Transwell assays, an increase of cells' proliferation and migration was detected in urine culture group compared with no urine culture group (p < 0.05).
    Conclusion: Urine may speed up the re-epithelialization process for prostatic urethra wounds by promoting proliferation and migration of prostate epithelial cells.

    Abstract 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). The treated bamboo was exposed outdoors for 26 weeks to evaluate the development of cracks. Results showed as follows: the initial split of PEG-PH-treated bamboo appeared after 22 weeks, while that of the controls after 2 weeks, the total length of cracks was 2271.31 and 873.5 mm for the control and PEG-PH-treated bamboo, respectively. To reveal the reasons for reduced cracks, scanning electron micrograph (SEM) was employed to observe the microstructure of bamboo; besides, hydrophobicity of bamboo was characterized by the water contact angle. PEG can swell the cell wall and the better hydrophobicity of round bamboo could be achieved after PEG-PH treatment. Therefore, the combination of PEG immersion and paraffin heating is an effective and practicable method in bamboo treatment, especially for round bamboo with high moisture content.

    Abstract Background: Drainage tube removal is difficult when the greater omentum becomes incarcerated in the drainage tube through the side holes. Currently, known removal methods are either ineffective or will cause additional damage to the patient in a secondary operation. Ureteroscopy and the holmium laser have been used in various surgical techniques in urology, and in theory, they are expected to be a good strategy for solving the problem of tissue incarceration.
    Case summary: Four patients diagnosed with difficult removal of an abdominal drainage tube following abdominal surgery are reported. All patients underwent surgery to remove the incarcerated greater omentum in the drainage tube using a holmium laser and a ureteroscope, and a new 16-F drain was then placed in the abdominal or pelvic cavity. The efficacy of this technique was evaluated by intraoperative conditions, success rate, and operating time; safety was evaluated by perioperative conditions and the probability of postoperative complications. All four operations went smoothly, and the drains were successfully removed in all patients. The average operating time was 24.5 min. Intraoperatively, the average irrigation volume was 892.0 mL, the average drainage volume was 638.5 mL, and no bleeding or damage to surrounding tissues was observed. Postoperatively, the average drainage volume was 32.8 mL and the new drains were removed within 36 h. All patients were able to get out of bed and move around within 12 h. Their visual analogue pain scores were all below 3. The average follow-up duration was 12.5 mo and no complications such as fever or bleeding were noted.
    Conclusion: Ureteroscopic holmium laser surgery is an effective, safe and minimally invasive technique for removing drains where the greater omentum is incarcerated in the abdominal drain.
