Enhanced recovery after surgery (ERAS) measures have not been systematically applied in transurethral surgery for benign prostatic hyperplasia (BPH). This study was performed on patients with BPH who required surgical intervention. From July 2019 to June 2020, the ERAS program was applied to 248 patients, and the conventional program was applied to 238 patients. After 1 year of follow-up, the differences between the ERAS group and the conventional group were evaluated. The ERAS group had a shorter time of urinary catheterization compared with the conventional group (mean ± standard deviation [s.d.]: 1.0 ± 0.4 days vs 2.7 ± 0.8 days, P < 0.01), and the pain (mean ± s.d.) was significantly reduced through postoperative hospitalization days (PODs) 0-2 (POD 0: 1.7 ± 0.8 vs 2.4 ± 1.0, P < 0.01; POD 1: 1.6 ± 0.9 vs 3.5 ± 1.3, P < 0.01; POD 2: 1.2 ± 0.7 vs 3.0 ± 1.3, P < 0.01). No statistically significant difference was found in the rate of postoperative complications, such as postoperative bleeding (P = 0.79), urinary retention (P = 0.40), fever (P = 0.55), and readmission (P = 0.71). The hospitalization cost of the ERAS group was similar to that of the conventional group (mean ± s.d.: 16 927.8 ± 5808.1 Chinese Yuan [CNY] vs 17 044.1 ± 5830.7 CNY, P =0.85). The International Prostate Symptom Scores (IPSS) and quality of life (QoL) scores in the two groups were also similar when compared at 1 month, 3 months, 6 months, and 12 months after discharge. The ERAS program we conducted was safe, repeatable, and efficient. In conclusion, patients undergoing the ERAS program experienced less postoperative stress than those undergoing the conventional program.

OBJECTIVES: To investigate the effect of progressive pre-disconnection of urethral mucosal flap during transurethral plasmakinetic enucleation of prostate (TUPEP) on early recovery of urinary continence. METHODS: Clinical data of patients with benign prostatic hyperplasia (BPH) admitted in Zhujiang Hospital of Southern Medical University during February and May 2022 were collected. All the patients underwent TUPEP, and the progressive pre-disconnection of urethral mucosal flap was performed in the procedure. The total operation time, enucleation time, postoperative bladder irrigation time and catheter indwelling time were recorded. Urinary continence was evaluated 24 h, 1 week, and 1, 3, 6 months after the removal of urinary catheter. RESULTS: All surgeries were successfully completed at one time with less intraoperative bleeding, and there were no complications such as rectal injury, bladder injury or perforation of prostate capsule. The total operation time was (62.2±6.5) min, the enucleation time was (42.8±5.2) min, the postoperative hemoglobin decrease by (9.5±4.5) g/L, the postoperative bladder irrigation time was (7.9±1.4) h, and the postoperative catheter indwelling time was 10.0 (9.2, 11.4) h. Only 2 patients (3.6%) had transient urinary incontinence within 24 h after catheter removal. No urinary incontinence occurred at 1 week, and 1, 3, 6 months after operation, and no safety pad was needed. The Qmax at 1 month after operation was 22.3 (20.6, 24.4) mL/s, international prostate symptom scores were 8.0 (7.0, 9.0), 5.0 (4.0, 6.0) and 4.0 (3.0, 4.0) at 1, 3 and 6 months after surgery, and quality of life scores at 1, 3 and 6 months after surgery were 3.0 (2.0, 3.0), 2.0 (1.0, 2.0) and 1.0 (1.0, 2.0), all of these indicators were better than those before surgery (all P<0.01). CONCLUSIONS In the treatment of BPH, the application of progressive pre-disconnection of urethral mucosal flap in TUPEP can completely remove the hyperplastic glands and promote early recovery of postoperative urinary continence with less perioperative bleeding and decreased surgical complications.

Benign prostatic hyperplasia (BPH) is a common disease in elderly men, and transurethral laser prostatectomy (TULP) has been widely used in the clinic to remove bladder outlet obstruction caused by BPH. Previous animal models for wound repair after prostatectomy have many limitations, and there have been no previous reports of a mouse model of TULP. Therefore, this study aimed to establish a novel mouse model of TULP. Twelve healthy adult Kunming (KM) mice received transurethral laser vaporization prostatectomy with a 200-μm thulium laser. The mice were sacrificed, and wound specimens from the prostatic urethra and bladder neck were harvested at 1 day, 3 days, 5 days, and 7 days after surgery. Hematoxylin-eosin (HE) and immunohistochemistry were applied to confirm the establishment of the mouse TULP model. One day after the surgery, urothelium expressing uroplakin (UPK) was absent in the urethral wound site, and a large number of necrotic tissues were found in the wound site. There was no UPK-positive urothelium in the wound 3 days after surgery. At 5 days after surgery, monolayer urothelium expressing UPK was found in the wound site, indicating that the re-epithelization of the wound had been completed. On the 7^th day after surgery, there were multiple layers of urothelium with UPK expression, indicating that the repair was completed. It is feasible to establish a mouse TULP model by using a microcystoscope system and a 200-μm thulium laser.

Objective: To analyze the clinicopathological features of IgG4-related diseases (RD) of retroperitoneum and the urinary and male reproductive system (IgG4-RUMR). Methods: A total of 11 IgG4-RUMR cases from January 2013 to March 2021 were retrospectively collected at Peking University Third Hospital and Shandong Provincial Hospital affiliated to Shandong First Medical University. The clinicopathologic features, laboratory and imaging findings were analyzed and scored according to the 2019 ACR/EULAR classification criteria for IgG4-RD. Results: The 11 patients (male:female is 9∶2; mean age 59 years, range from 44 to 83 years) were initially admitted to the Deparment of Urology/Kidney Transplantation (10 cases) and the Department of Oncology (1 case). All patients had urogenital disorders or imaging abnormalities. Three of the 11 patients had a history of IgG4-RD such as lacrimal gland engorgement, salivary gland engorgement and IgG4-associated pancreatitis. Abnormal retroperitoneal soft tissue and hydronephrosis were found in eight cases, while epididymal and spermatic cord masses were found in one case, simple renal mass in one case, and"benign prostatic hyperplasia"in one case. In the 10 patients tested for serum IgG4, the serum IgG4 level was 0.8-14.4 g/L. Histologically, all cases showed significant lymphoplasmacytic infiltration and storiform fibrosis, and some were accompanied by obliterative phlebitis. The number of IgG4 positive plasma cells was 12-155 per high-power field, and the IgG4/IgG ratio was 15%-77%. According to the 2019 ACR/EULAR IgG4-RD classification standard 11 cases scored 20-48 points, all of which met the diagnostic criteria of IgG4-RUMR. Therapeutically, the patient with a simple renal mass underwent partial nephrectomy. The patient with prostate lesion underwent transurethral resection of prostate and was initially diagnosed as nonspecific chronic prostatitis. Later, the patient was admitted again because of salivary gland swelling, and the pathologic diagnosis was amended. The patient with epididymal and spermatic cord masses participated in a clinical trial about retroperitoneal fibrosis. The remaining eight patients received symptomatic treatment such as adhesiolysis and stent placement. All the patients were subsequently treated with glucocorticoid/immunosuppressant and symptoms relieved. Conclusions: IgG4-RUMR is uncommon. In clinical practice, information from clinical, serologic, radiologic and pathologic evaluations must be integrated. IgG4-RUMR should be considered in the differential diagnosis of urinary and male reproductive diseases. The 2019 ACR/EULAR classification criteria for IgG4-RD, while relatively complex, are objective and practical in the diagnosis of IgG4-RUMR.

The prevalence of benign prostatic hyperplasia (BPH) is rising with Korea becoming an aging society. As patients age, their comorbidities and the risks associated with anesthesia increase. Recently, there has been an increasing concern regarding sexual function after surgery. As a result, interest in minimally invasive surgery for BPH that does not require anesthesia or affect sexual function has grown. This review article introduces newly developed minimally invasive surgeries for BPH divided into four categories based on the strategy—mechanical, anatomical, atrophic, and laparoscopic. Here, the mechanisms for each surgical method have been introduced. Furthermore, recent representative studies of these procedures with a focus on randomized controlled trials and meta-analyses have also been reviewed. Side effects related to sexual function have also been mentioned briefly along with the efficacy and indication for robotic BPH surgery, which has recently been attracting attention. However, these newer, minimally invasive procedures require additional comparative randomized controlled trials and long-term results to produce more robust evidence for their use.

OBJECTIVE: To investigate the clinical and pathologic characteristics, diagnosis, treatment, prognosis and survival of prostatic stromal tumor of uncertain malignant potential. METHODS: Overall 14 patients with prostatic stromal tumor of uncertain malignant potential were treated from October 2008 to April 2020, the patient age ranged from 27 to 78 years (mean 54 years). The disease duration was 1 to 180 months (mean duration of 46 months). The clinical manifestations mainly included urinary obstructive symptoms and urethral irritating symptoms. The tumors were located in the peripheral zone or the transition zone. Digital rectum examination indicated prostatic tumor. Serum prostatic specific antigen level was always normal or elevated. Transrectal ultrasonography and magnetic resonance imaging indicated prostatic tumor. Magnetic resonance imaging in showed large, round, well-defined masses, which were diffusely heterogeneous signal on T2 weighted imaging. Following the administration of intravenous contrast medium, the lesion had diffuse and heterogeneous enhancement. RESULTS: In the study, 3 cases underwent prostate biopsy, 2 cases underwent transurethral resection of the prostate, 9 cases underwent radical excision or transurethral resection of the prostate with definite diagnosis of pathologic features. Under the light microscope, the interstitial cells of stromal tumor of uncertain malignant potential were overgrowth and fusiform cells showed some degree of pleomorphism, nuclei with few mitotic figures, and necrosis was not often seen. Immunohistochemical staining showed that prostate specific antigen was negative, while vimentin was positive in the tumor tissue, CD34, progesterone receptor and smooth muscle actin were positive in the majority, and Ki67 positive index was 1%-20% (mean 6%). Twelve cases were followed-up, and the time of survival varied from 10 to 96 months (mean 65 months), two cases were lost to the follow-up, one case died of disease at the end of 10 months, nine cases were free of disease recurrence after surgery, two cases underwent more transurethral resection of the prostate due to local recurrence. CONCLUSION STUMP is a very rare tumor of the specialized prostatic stroma with an unpredictable clinical behavior. The clinical manifestations, transrectal ultrasonography and magnetic resonance imaging are valuable for the diagnosis of prostatic stromal tumor of uncertain malignant potential. Its definite diagnosis depends on pathological examination. Up to now, early surgery and combined therapy are effective treatments for prostatic stromal tumor of uncertain malignant potential.

Biochemical recurrence (BCR) is important for measuring the oncological outcomes of patients who undergo radical prostatectomy (RP). Whether transurethral resection of the prostate (TURP) has negative postoperative effects on oncological outcomes remains controversial. The primary aim of our retrospective study was to determine whether a history of TURP could affect the postoperative BCR rate. We retrospectively reviewed patients with prostate cancer (PCa) who had undergone RP between January 2009 and October 2017. Clinical data on age, prostate volume, serum prostate-specific antigen levels (PSA), biopsy Gleason score (GS), metastasis stage (TNM), D'Amico classification, and American Society of Anesthesiologists (ASA) classification were collected. Statistical analyses including Cox proportional hazard models and sensitivity analyses which included propensity score matching, were performed, and the inverse-probability-of-treatment-weighted estimator and standardized mortality ratio-weighted estimator were determined. We included 1083 patients, of which 118 had a history of TURP. Before matching, the non-TURP group differed from the TURP group with respect to GS (P= 0.047), prostate volume (mean: 45.19 vs 36.00 ml, P < 0.001), and PSA level (mean: 29.41 vs 15.11 ng ml^-1, P= 0.001). After adjusting for age, PSA level, T stage, N stage, M stage, and GS, the TURP group showed higher risk of BCR (hazard ratio [HR]: 2.27, 95% confidence interval [CI]: 1.13-3.94, P= 0.004). After matching (ratio 1:4), patients who underwent TURP were still more likely to develop BCR according to the adjusted propensity score (HR: 2.00, 95% CI: 1.05-3.79, P= 0.034). Among patients with PCa, those with a history of TURP were more likely to develop BCR after RP.

For more than nine decades, transurethral resection of the prostate remains the gold standard for the surgical treatment of lower urinary tract symptoms due to benign prostatic obstruction. The occurrence of urethral strictures after transurethral resection of the prostate is one of the major late complications and has been reported as the leading cause of iatrogenic urethral strictures in patients older than 45 years who underwent urethroplasty. Although several postulations have been proposed to explain the urethral stricture after transurethral resection of the prostate, the exact etiology of urethral stricture after TURP is still controversial. Suggested etiological factors of urethral stricture formation after transurethral resection of the prostate include infection, mechanical trauma, prolonged indwelling catheter time, use of local anesthesia, and electrical injury by a stray current. One single treatment option is not appropriate for all stricture types. The management of urethral stricture following transurethral resection of the prostate includes minimally invasive endoscopic methods, including urethral dilation and direct visual incision, or open surgical procedures with varying urethroplasty techniques. Although scientific studies focusing on urethral strictures after transurethral resection of the prostate are relatively limited and sparse, we can apply the principles of urethral stricture management before making decisions on individual stricture treatment.

PURPOSE: There are no established statistical data available for the comparison of different surgical methods adopted for the resection of benign prostatic hyperplasia (BPH). This study investigates the present status related to BPH surgery in Korea for the past 8 years. METHODS: National-level data from the National Health Insurance Service and National Statistical Office were analyzed in this study. From 2010 to 2017, the trends of surgeries for BPH were reviewed according to the procedure code including transurethral resection of the prostate (TURP), holmium laser enucleation of the prostate (HoLEP), or high-power potassium titanyl phosphate (KTP), and this trend also analyzed by age, geographic distribution, and hospital type. RESULTS: Over the past 8 years, there was not much change in the total number of BPH-related surgeries (range, 10,393– 11,072). Although there was not much alteration in the number of conventional TURP (from 6,801 in 2010 to 6,645 in 2017), the number of HoLEP has dramatically increased (from 278 in 2010 to 3,805 in 2017). The number of HoLEP surgeries after 2011 exceeded the number of surgeries using KTP, and the gap is anticipated to rise. The number of surgeries by age group was most common in the 70s and the total number of surgeries is decreasing in all age groups; for HoLEP, the trend is steadily increasing over the age of 60 years. Most of the BPH surgeries were performed in metropolitan areas, such as Seoul, Gyeonggi-do, and Busan, and in larger hospitals compared to smaller hospital settings. CONCLUSIONS: Through the data of the National Health Insurance Service, we could apprehend the present status of BPH-related surgery in Korea. Then, we could know about the trend according to several factors and we think these results will be valuable as academic references as well.
