We report a case involving an 85-year-old man who underwent laparoscopic radical prostatectomy for prostate cancer in 2011. During follow-up, he required long-term use of a penile clamp to manage urination due to permanent severe stress incontinence. In February 2023, he presented with a painless cystic mass in the scrotum. Upon pressing the mass with hand, fluid drained from the external urethral orifice, causing the mass to shrink in size, although it returned to its original size a few hours later. Urography and cystoscopy showed a globular urethral diverticulum located anteriorly. The patient underwent surgical excision of the diverticulum along with urethroplasty. Postoperatively, the urinary stress incontinence persisted, but he declined any further surgical intervention. An artificial urinary sphincter is currently the first-line treatment for male urinary incontinence. However, devices such as penile clamps can serve as an alternative when considering surgical suitability or cost. It is important to note that these devices can lead to serious complications such as urethral erosion, stricture, or diverticulum. Therefore, caution is advised when using such devices, and they should be removed periodically at short intervals.

OBJECTIVE:
To investigate the clinical effect of transposition of gracilis muscle flap in repairing urethral perineal fistula after Miles operation.
METHODS:
The clinical data of 3 patients with urethral perineal fistula treated in the Second Affiliated Hospital of Zhejiang University from September 2023 to November 2024 were analyzed retrospectively. All patients were male, aged from 59 to 68 years (mean 63 years). All patients underwent Miles operation because of low rectal cancer. Urethral perineal fistula occurred after 2 months to 13 years of the operation. The underlying comorbidities included diabetes (2/3), preoperative chemoradiotherapy (1/3), and chemotherapy alone (1/3). The endourethral fistula was located in the apical and membranous part of the prostate, with a diameter of 1.5-2.0 cm and a mean of 1.7 cm. Suprapubic cystostomy was performed one month before operation. In all 3 cases, perineal inverted "Y" incision was taken under general anesthesia to expose urethral fistula, cut off necrotic tissue and suture urethral fistula. The gracilis muscle of the right thigh was taken and turned through the perineal subcutaneous tunnel. and 6 stitches were suture at the urethral fistula.
RESULTS:
The operations of all 3 patients were completed successfully. The follow-up period ranged from 2 months to 12 months, with an average of 8 months. There was no case of urinary incontinence after removal of catheter 3 weeks after operation. In two patients, urethrography was reviewed 1 month after surgery to show no fistula residue and urethral stenosis, and the fistula was removed. In one patient with a history of radiotherapy, urethrography was reviewed 1 month after surgery to show a small amount of contrast overflow around the urethra, and urethrography was reviewed again 3 months after surgery to show no contrast overflow around the urethra. All the 3 patients had no disturbance of movement of the right lower limb, and the pain of different degrees of thigh incision was acceptable and basically relieved half a month after operation.
CONCLUSION
Gracilis muscle flap is one of the effective methods for repairing urethral perineal fistula after Miles operation,which has a precise surgical result and few complications.

Acta Academiae Medicinae Sinicae 2022;44(2):227-235
Objective To investigate the clinical characteristics and genetic mutations in Kindler syndrome(KS)and provide a theoretical basis for the diagnosis and treatment of KS. Methods The clinical data of one case of KS from Peking Union Medical College Hospital and 185 cases reported in literature were collected. The gene mutation types,patient clinical data,and tumor characteristics were statistically analyzed. Results A total of 186 cases were enrolled,including 110 males and 76 females,with the mean age of(28±16)years. The data of gene mutation and specific clinical manifestations were available in 151 and 94 patients,respectively. The main clinical manifestations of KS included poikiloderma,occurrence of blister in childhood,and photosensitivity,and the secondary clinical manifestations included oral inflammation,palmoplantar keratoderma,webbing/pseudoainhum,dysphagia,urethral stricture and so on.Oral inflammation(r=0.234,P=0.023),palmoplantar keratoderma(r=0.325,P=0.001),webbing/pseudoainhum(r=0.247,P=0.016),dysphagia(r=0.333,P=0.001),urethral stricture(r=0.280,P=0.006)were significantly correlated with age,showing significantly higher incidence in the patients over 32 years old.Urethral stricture(χ2=11.292,P=0.001)and anal stenosis(χ2=4.014,P=0.045)were significantly correlated with sex,with higher incidence in males.Eighty different mutations were found in 151 patients,and the most common gene mutation was c.676C>T.Forty-one tumors occurred in 27 patients,among which squamous cell carcinoma accounted for 92.7%. The gene mutation site had no significant correlation with squamous cell carcinoma or patient country. Conclusions The c.676C>T in FERMT1 gene is the most common mutation in KS.The patients are prone to squamous cell carcinoma and mainly attacked at the exposure sites(hand and mouth).

The use of artificial urinary sphincter (AUS) for the treatment of stress urinary incontinence has become more prevalent, especially in the "prostate-specific antigen (PSA)-era", when more patients are treated for localized prostate cancer. The first widely accepted device was the AMS 800, but since then, other devices have also entered the market. While efficacy has increased with improvements in technology and technique, and patient satisfaction is high, AUS implantation still has inherent risks and complications of any implant surgery, in addition to the unique challenges of urethral complications that may be associated with the cuff. Furthermore, the unique nature of the AUS, with a control pump, reservoir, balloon cuff, and connecting tubing, means that mechanical complications can also arise from these individual parts. This article aims to present and summarize the current literature on the management of complications of AUS, especially urethral atrophy. We conducted a literature search on PubMed from January 1990 to December 2018 on AUS complications and their management. We review the various potential complications and their management. AUS complications are either mechanical or nonmechanical complications. Mechanical complications usually involve malfunction of the AUS. Nonmechanical complications include infection, urethral atrophy, cuff erosion, and stricture. Challenges exist especially in the management of urethral atrophy, with both tandem implants, transcorporal cuffs, and cuff downsizing all postulated as potential remedies. Although complications from AUS implants are not common, knowledge of the management of these issues are crucial to ensure care for patients with these implants. Further studies are needed to further evaluate these techniques.

PURPOSE: The main goal of this retrospective study is to explore the predictors of success in learning clean intermittent self-catheterization (CISC) in patients over 65 years of age. The secondary goal is to assess whether in this population, the risk of failure to perform CISC is greater, compared with patients under 65 with similar pathologies. METHODS: All patients older than 65 consulting between January 2011 and January 2016 for learning CISC were included. A control population younger than 65 matching with sex, body mass index, and pathology was selected. RESULTS: One hundred sixty-nine of the 202 patients (83.7%) over 65 succeeded in learning CISC. Obesity (P < 0.05), low pencil and paper test (PP test) (P < 0.01) and low functional independence measure (FIM) (P < 0.01) scores were risk factors of failure. No significant differences were found with sex or pathology. In multivariate analysis, low PP test perineum access (odds ratio [95% confidence interval], 2.30 [1.32–4.42]), low FIM motor (1.04 [1.01–1.08]), and FIM cognition (1.18 [1.03–1.37]) scores were independent factors of learning failure. Compared to control group, age over 65 was not predictive of failure (P=0.15). CONCLUSIONS: Our study shows that success in learning CISC does not depend on age but on difficulties in mobility, access to perineum and probably cognitive disorders.

PURPOSE: The pathophysiological role of detrusor overactivity (DO) in the bladder, which is commonly observed in various bladder diseases, is not well understood. DO appears in bladder outlet obstruction (BOO), and may continue even after subsequent deobstruction. DO therefore provides an excellent opportunity to observe molecular biological changes. METHODS: In this study, to understand the molecular effects of persistent DO after BOO induction and deobstruction, we performed awake cystometry on female Sprague-Dawley rats divided into 4 groups: a sham group, a BOO group, a deobstructed group with DO after BOO (DDO), and a deobstructed group without DO after BOO (non-DDO). Total RNA was extracted from the bladder samples, and gene expression profiles were compared between the sham and model groups. RESULTS: DO was observed in 5 of the 6 rats (83%) in the BOO group, and in 6 of the 13 rats (46%) in the deobstructed group. The non-DDO group showed a significantly greater residual volume than the DDO group. Through a clustering analysis of gene expression profiles, we identified 7,532 common upregulated and downregulated genes, the expression of which changed by more than 2 fold. In the BOO group, 898 upregulated and 2,911 downregulated genes were identified. The non-DDO group showed 3,472 upregulated and 4,025 downregulated genes, whereas in the DDO group, only 145 and 72 genes were upregulated and downregulated, respectively. CONCLUSIONS: Abnormal function and gene expression profiles in bladders after BOO were normalized in the BOO rats with DO after deobstruction, whereas in those without DO, abnormal function persisted and the gene expression profile became more abnormal. DO may play a protective role against the stress to the bladder induced by BOO and deobstruction as a form of adaptive neuroplasticity.

PURPOSE: Augmentation enterocystoplasty (AE) has been shown to improve clinical symptoms in patients with end-stage bladder disease (ESBD). Herein, we report the long-term outcomes of a series of patients with different etiologies of ESBD who received AE. METHODS: We retrospectively reviewed 102 patients with ESBD who received AE at the Hualien Tzu Chi General Hospital from 1992 to 2014. ESBD in this study was defined as including neurogenic lower urinary tract dysfunction (NLUTD) due to spinal cord injury (SCI) or myelomeningocele, inflammatory bladder disease (IBD), ESBD occurring after pelvic cancer surgery, and other etiologies. Complications including active lower urinary tract problems and urinary tract infection (UTI), as well as patients’ self-reported satisfaction with the procedure, were evaluated. RESULTS: A total of 102 patients were included in the study. A majority of patients received AE for NLUTD (n=43), followed by IBD (n=38), ESBD after pelvic cancer surgery (n=15), and the other etiologies (n=6). Patients had a mean age of 39.4±18.7 years and were followed for a mean of 78 months. All patients had significantly increased cystometric bladder capacity and compliance at the time of follow-up. Fifty-four patients (52.9%) reported moderate to excellent satisfaction with the outcome, and there were no significant differences among the groups (P=0.430). The most common reason for dissatisfaction was the need for clean intermittent catheterization (CIC; 41.7%), followed by urinary incontinence (25.0%) and recurrent UTI (16.7%). CONCLUSIONS: AE is a safe and effective procedure for patients with ESBD. Postoperative urinary incontinence and UTI as well as the need for CIC may affect quality of life and decrease patient satisfaction.

Renal tubulointerstitial fibrosis is the common ending of progressive renal disease. It is worth developing new ways to stop the progress of renal fibrosis. Peroxisome proliferator-activated receptor-γ (PPARγ) agonists have been studied to treat diabetic nephropathy, cisplatin-induced acute renal injury, ischemia reperfusion injury and adriamycin nephropathy. In this study, unilateral ureteral obstruction (UUO) was used to establish a different renal fibrosis model. PPAR? agonist pioglitazone was administrated by oral gavage and saline was used as control. At 7th and 14th day after the operation, mice were sacrificed for fibrosis test and T lymphocytes subsets test. Unexpectedly, through MASSON staining, immunohistochemistry for α-SMA, and Western blotting for a-SMA and PDGFR-β, we found that pioglitazone failed to attenuate renal fibrosis in UUO mice. However, flow cytometry showed that pioglitazone down-regulated Th1 cells, and up-regulated Th2 cells, Th17 cells and Treg cells. But the Th17/Treg ratio had no significant change by pioglitazone. Real-time PCR results showed that TGF-β and MCP-1 had no significant changes, at the same time, CD4(+) T cells associated cytokines were partially regulated by pioglitazone pretreatment. Taken together, pioglitazone failed to suppress renal fibrosis progression caused by UUO.
