RESUMEN
A 19-year-old man had been aware of dysuria and urinary incontinence since childhood but did not seek medical attention. He was diagnosed with acute pyelonephritis due to lower urinary tract dysfunction associated with spina bifida occulta and tethered cord syndrome (TCS) due to spinal cord lipoma. After placement of a urethral catheter and antibacterial chemotherapy, the patient was cured of acute pyelonephritis. He was treated with solifenacin and started clean self-intermittent catheterization (CIC). Shortly after the start of CIC, the acute pyelonephritis flared up again, and he was managed with a reinserted urethral catheter until an untethering operation. Preoperative video urodynamics showed that the bladder morphology was Ogawa classification grade III with vesicoureteral reflux (VUR) at 92 ml infusion. With the combination of an untethering operation and additional mirabegron, the functional bladder capacity was increased to 353 ml and VUR improved, allowing for safe urinary management of the CIC. TCS can be diagnosed at any age and requires appropriate urinary management and therapeutic intervention as early as possible after diagnosis.

Prostatic hyperplasia is very common in elderly men and is a typical disease that reduces quality of life. Histologically, hyperplasia of the prostate gland causes obstruction at the bladder outlet, resulting in symptoms such as a weak urine stream. Various factors have been considered to cause histological enlargement of the prostate, but the underlying cause is still unknown. The factors that cause prostate hyperplasia can be broadly classified into intrinsic and extrinsic ones. Extrinsic factors include things that we directly come into contact with such as bacteria and food. On the other hand, intrinsic factors are those that cause changes in functions originally provided in the body due to some cause, including extrinsic factors, such as chronic inflammation and an imbalance of sex hormones. A large number of reports have been made to date regarding the etiology of prostatic hyperplasia, although they have not yet clarified the fundamental cause(s). The various factors currently known should be outlined for future research. Should it be possible to prevent this highly prevalent prostatic hyperplasia which is mainly cause of dcreasing quality of life, there is no doubt that it would be a huge contribution to humanity.

We experienced two cases of renal primary synovial sarcoma. Case 1: A 29-year-old man underwent laparoscopic radical nephrectomy and was originally diagnosed with renal cell carcinoma. Case 2: A 25-year-old man was treated by open radical nephrectomy since radiographical findings indicated tumor invasion to the ureter causing hydronephrosis. Both cases were pathologically diagnosed as renal synovial sarcomas, and were followed using computed tomography. Recurrence was observed within a year in both cases.

OBJECTIVES: Our previous study suggested that the operative procedure is critical for the development of parastomal hernia. We developed a novel procedure for the creation of an ileal conduit stoma to prevent parastomal hernia. Herein we evaluate the efficacy and safety of the procedure. METHODS: A total of 113 Japanese patients underwent radical cystectomy and ileal conduit diversion for bladder cancer from January 2017 through December 2021 at our institution. After excluding those with incomplete data, 103 patients consisting of 46 (44.7%) with the conventional procedure and 57 (55.3%) with the novel procedure were consecutively enrolled. The main points of the novel procedure are as follows: (1) the passage of the ileal conduit is ≤2.4 cm in diameter in principle; (2) the posterior rectus sheath and peritoneum are vertically incised 2 cm laterally from the middle of the stoma site to make an oblique passage for the ileal conduit; and (3) the anterior rectus sheath and posterior rectus sheath with peritoneum are fixed to the ileal conduit separately. RESULTS: Radiography-based parastomal hernia was observed in 11 patients (10.7%) with a median follow-up of 22.0 months. The incidences of parastomal hernia were 3.5% and 19.6% in the novel and the conventional procedure groups, respectively (p = 0.011). The former had a significantly lower cumulative incidence of parastomal hernia (p = 0.008, log-rank test). No specific complications associated with the procedure were observed. CONCLUSIONS: The results of the preliminary cohort study suggest that the novel procedure is safe and effective for the prevention of parastomal hernia.

BACKGROUND: Numerous studies have investigated the associations between maternal nutritional status and various diseases, with the underlying mechanism often attributed to epigenetic changes. However, limited research has been conducted on the relationship between maternal nutrition and benign prostatic hyperplasia (BPH). In this study, we aimed to explore the potential association between maternal nutrition and BPH using an animal experiment and evaluating the findings through fluorescent immunostaining and genetic analysis. METHODS: Female spontaneously hypertensive rats (SHR/Izm) were randomly assigned to three groups at the start of pregnancy: a standard diet group (SD; 17% protein, 7% fat), a low-protein diet group (LPD; 6% protein, 7% fat), and a high-fat diet group (HFD; 22% protein, 35% fat). The diets were maintained throughout gestation. After giving birth, both the mothers and their pups were exclusively fed a standard diet. Male pups were euthanized at 48 weeks, and their prostates were removed. The composition of the ventral prostate (VP) was evaluated using fluorescent immunostaining with antibodies for cytokeratin, vimentin, and Ki-67. Microarray analysis, real-time RT-PCR, and DNA methylation analysis using pyrosequencing were performed. Statistical analysis was conducted using one-way ANOVA and Tukey's multiple comparison test, with a significance level set at p < 0.05. RESULTS: Pups in the LPD group exhibited significant underweight from birth (1 day; SD vs. LPD vs. HFD: 4.46 vs. 4.08 vs. 4.35, p = 0.04) until weaning (21 days; SD vs. LPD vs. HFD: 30.8 vs. 27.4 vs. 29.2, p = 0.03). However, they exhibited catch-up growth, and there was no significant difference at 48 weeks (p = 0.84). The epithelial area in the ventral prostate was significantly increased in the LPD group (SD vs. LPD vs. HFD: 39% vs. 48% vs. 37%, p = 0.01), while the stromal area was significantly increased in the HFD group (SD vs. LPD vs. HFD: 11% vs. 11% vs. 15%, p < 0.01). Gene ontology analysis of the gene expression microarray showed increased activity in developmental processes (SD vs. LPD: p = 6.3E-03, SD vs. HFD: p = 7.2E-03), anatomical structure development (SD vs. LPD: p = 6.3E-03, SD vs. HFD: p = 5.3E-03), and cell differentiation (SD vs. LPD: p = 0.018, SD vs. HFD: p = 0.041) in both the LPD and HFD groups. Real-time RT-PCR revealed high expression levels of the transcription factors NFκB (p < 0.01) and Smad3 (p < 0.01) in both the LPD and HFD groups. XIAP, an apoptosis inhibitor, was increased in the LPD group (p = 0.02). The TGF beta pathway, associated with epithelial mesenchymal transition (EMT), and vimentin (p < 0.01) were upregulated in the HFD group. Pyrosequencing DNA methylation analysis of the TGF beta pathway indicated hypomethylation of TGFb1, TGFbR1, and Smad3 in all groups, although there were no significant differences. CONCLUSIONS: Our findings suggest that both maternal undernutrition and obesity influence the prostatic development of offspring. Maternal consumption of a low protein diet promotes epithelial hyperplasia through the upregulation of apoptosis inhibitors, while a high fat diet leads to increased stromal growth through the induction of EMT.

BACKGROUND: Sarcoidosis affects multiple organs and exhibits diverse clinical manifestations. Although tubulointerstitial nephritis is a known feature of renal involvement, necrotizing vasculitis is rare. Furthermore, prostate involvement with urinary retention is unusual in patients with sarcoidosis. Here, we report a case of systemic sarcoidosis with a rare combination of manifestations and different acute kidney injuries. CASE PRESENTATION: A 66-year-old man developed sudden urinary retention and fever. He was diagnosed with prostatitis and admitted to our hospital. An indwelling urethral catheter was inserted, and antimicrobial therapy was initiated; however, the prostatitis was refractory. Computed tomography revealed enlarged mediastinal lymph nodes. Analysis of transbronchoscopic lymph node and prostate biopsies showed epithelioid cell granulomas, suggesting systemic sarcoidosis. During the clinical course, the serum creatinine level rapidly increased to 2.36 mg/dL without oliguria. A kidney biopsy revealed tubulointerstitial injury with moderate lymphohistiocytic infiltration and small-vessel vasculitis in the interstitium. Following oral administration of 60 mg/day prednisolone, the patient's renal function immediately improved, and urinary retention did not recur. CONCLUSIONS: To the best of our knowledge, this is the first reported case of sarcoidosis with two unusual complications. Given its clinical course and pathology, this case is clinically valuable.

OBJECTIVES: We previously demonstrated the efficacy of cognitive behavioral therapy (CBT) using a self-check sheet for patients with nocturia in a randomized controlled study. Additionally, we investigated the efficacy of the intervention in real-world clinical practice. METHODS: Two hundred forty-three outpatients with complaint of nocturia who practiced CBT for 4 weeks using a self-check sheet were included in this trial, which took place from April 2021 to March 2022 in 20 institutions. RESULTS: Of the 243 patients, 215 who achieved 50% or more of the behavioral therapy tasks were included in the analysis. Their mean age ± SD was 77.1 ± 7.7. A significant decrease was observed in nighttime frequency at 4 weeks after CBT using self-check sheets (pre 3.3 and post 2.8, p < .001). Nighttime frequency was decreased one or more times and was defined as treatment success in 102 patients (47.4%). Pretreatment nighttime frequency in the treatment-success group was significantly higher than that of the failure group (3.5 ± 1.0 vs. 3.2 ± 1.0, p = .013). In multivariate logistic regression analysis, predictive factors of treatment success were pretreatment nocturnal frequency of four or more (odds ratio [OR] 1.82, 95% confidence interval [CI] 1.01-3.30; p = .046) and the absence of diabetes mellitus (OR 3.08, 95% CI 1.34-7.06; p = .008). CONCLUSIONS: CBT using a self-check sheet requiring less time, less labor, less cost, and less medication is very beneficial for both patients and medical staff in real-world clinical practice.

Objectives: We aimed to prospectively compare lower urinary tract symptoms in premenopausal and postmenopausal women with acute uncomplicated cystitis before and after antibiotic therapy. Materials and methods: This study included adult women with acute uncomplicated cystitis who visited 4 institutions between 2019 and 2020. After registration, we administered oral antibiotics and prospectively documented the changes in lower urinary tract symptoms from the first visit to a follow-up visit at 1 week using the Core Lower Urinary Tract Symptoms Score (CLSS) questionnaire. Results: After treatment, pyuria disappeared in 60 of the 66 patients (14 premenopausal and 46 postmenopausal). The CLSS total score (range) changed from 13 (3-29) to 4 (0-18) with a significant improvement in all CLSS items. At baseline, nocturia, urgency, and urgency incontinence were more prominent in postmenopausal women than in premenopausal women. In contrast, baseline urethral pain and quality of life index were more severe in premenopausal women than in postmenopausal women. After treatment, the CLSS total score was still higher in postmenopausal women, as reflected by the relatively higher scores for nocturia and urgency, irrespective of the comparable scores for urethral pain and the quality of life index in the 2 groups. Conclusions: Our results suggest that if storage symptoms persist, they should be carefully interpreted according to menopausal status.
RESUMEN
OBJECTIVES: To clarify Japanese real-world clinical data on the use of desmopressin 25 and 50 µg orally disintegrating tablets (ODT) for male patients with nocturia and evaluate the predictive factors to improve nighttime frequency. METHODS: We retrospectively accumulated real-world clinical data from 27 institutions in Japan. Male patients with two or more episodes of nocturia who received desmopressin ODT for nocturnal polyuria (NP) from 2019 through 2021 were included. The primary endpoint was the change of nighttime frequency until 3 months after desmopressin administration. The secondary endpoints were to clarify the persistence rate, adverse events, and predictive factors of decreasing nighttime frequency. RESULTS: A total of 118 patients were eligible to participate in this study. The persistence rate of desmopressin on the Kaplan-Meier curve at week 12 was 51.3. The reason for discontinuation was mainly the occurrence of adverse events in 67 patients (56.8%), particularly hyponatremia in 7 patients (5.9%). Nighttime frequencies at baseline, - 1 month and 1 - 3 months after desmopressin administration were 4.1 ± 1.3, 2.9 ± 1.4 (P < .01), and 2.6 ± 1.3 (P < .01), respectively. The mean nighttime urine volume voided at baseline was significantly larger in patients whose nighttime frequency decreased by two or more times than in those with a decrease of less than two times. CONCLUSIONS: Desmopressin 25 and 50 µg ODT treatments are feasible for male patients with NP in Japanese real-world clinical practice. Patients with higher voided volumes, particularly in the nighttime, may have great benefit from desmopressin.

Background: Small cell carcinoma of the urinary bladder (SCUB) is rare. The optimal treatment for SCUB remains unclear. To address the problem of appropriate treatment for each case, we assessed single-modality and surgery-based multimodality treatments in patients with SCUB. Materials and methods: We retrospectively reviewed the medical records of 12 patients with SCUB between 1990 and 2013. All patients underwent transurethral resection of the bladder tumor and were diagnosed with SCUB. Their clinicopathological characteristics were assessed, and the outcomes were compared according to the treatment modality. Results: The median (range) age at diagnosis was 66 years (range, 53-85 years). T1-4N0M0 was observed in 8 patients (66%), N1-3M0 in 2 (17%), and NanyM1 in 2 (17%). After transurethral resection of the bladder tumor, 6 patients (50%) underwent cystectomy alone, and 4 (33%) underwent cystectomy and presurgical or adjuvant chemotherapy with etoposide and cisplatin. During the median follow-up period of 20.7 months, 6 patients (50%) died of cancer, and 2 patients (17%) died of other causes. The median overall survival period was 1.9 years. The 5-year overall survival rate in patients who underwent cystectomy and chemotherapy was 75%, whereas that in those who underwent cystectomy alone and transurethral resection alone were 22% and 0%, respectively (p = 0.012). Recurrence-free survival was significantly correlated with cause-specific survival (r = 0.95; 95% confidence interval, 0.81-0.99; p < 0.001). Conclusions: Radical cystectomy with chemotherapy using the etoposide and cisplatin regimen improved the prognosis of patients with SCUB and TxNxM0. The time from initial progression to death due to cancer was very short, indicating that the initial treatment strategy is crucial.
RESUMEN
A female patient with Xp11.2 translocation renal cell carcinoma developed lung metastasis 24 months after partial nephrectomy that was performed at the age of 32. Sunitinib, everolimus, axitinib, temsirolimus and pazopanib were sequentially administered for 55 months and disease progression was observed. Then nivolumab was started as 6th-line treatment. After a transient increase in tumor size, metastatic tumors started to shrink. Eventually, nivolumab provided a partial response with a 35% reduction of tumor size at 50 months and freedom from progression for 60 months. The present case suggests that immune checkpoint inhibitors are effective in selected cases with Xp11.2 translocation renal cell carcinoma.
RESUMEN
We report a case of open surgical hemostasis following transarterial embolization (TAE) that failed to stabilize the hemodynamics for renal injury after extracorporeal shock wave lithotripsy (ESWL). A 48-year-old man presented with severe left renal colic pain 1 day after ESWL for a left renal stone. Computed tomography revealed arterial bleeding from the lower pole of the left kidney and retroperitoneal hematoma. TAE was successfully performed for the lower poler bleeding. However, we were unable to complete the procedure for bleeding from an aberrant artery to the lower pole of the kidney that was supplied directly from the aorta. Therefore, an emergency laparotomy was performed and the injury in the aberrant artery was manually ligated. Hemostasis was obtained after the direct surgical ligation and he had a good postoperative recovery. Open surgical hemostasis is a treatment modality that should be considered following TAE that fails to control arterial bleeding after ESWL.

OBJECTIVE: To evaluate the efficacy and safety of vibegron in patients with overactive bladder (OAB) in real-world clinical practice in Japan. METHODS: This multicenter, prospective, non-controlled study consecutively enrolled patients with OAB determined by an OAB symptom score (OABSS) of three points or more and a question 3 (urgency) score of two points or more. A total of 212 patients from 43 institutions were recruited from January 2019 through March 2020. Vibegron, 50 mg, was administrated daily for 8 weeks as first-line monotherapy (first-line group, FL), monotherapy switching from antimuscarinics (post-antimuscarinic group, PA) or mirabegron (post-mirabegron group, PM) and combination therapy with antimuscarinics (add-on group). The OABSS was collected at baseline and every 2 weeks. Adverse events were recorded at every visit. RESULTS: Of the 212 patients registered, 188 (male 76, female 112) were eligible for analysis (124 in the FL group, 27 in PA, 29 in PM, and eight in the add-on group). The add-on group was excluded from further analysis due to its small number. The OABSS (mean ± SD) showed significant improvement in all groups (FL; 8.8 ± 2.5, 3.8 ± 2.8, PM; 9.4 ± 2.2, 4.5 ± 4.0, PM; 8.9 ± 2.5, 4.7 ± 3.3 at 0 and 8 weeks, respectively). The overall incidence of adverse events was 25%. No grade 3 or higher adverse events were observed. CONCLUSIONS: In the real-world clinical setting, vibegron is effective and well-tolerated by OAB patients, including those switching therapy from antimuscarinics and mirabegron.

A 44-year-old man was carried to the hospital in an ambulance because of dyspnea, paralysis and dysuria after signs of the flu. Acute encephalomyelitis was diagnosed by examination of magnetic resonance imaging. Antimicrobial treatment and respirator management was carried out with indwelling of urethral catheter for urinary retention. After improvement of encephalitis, the urethral catheter was removed. However, he still needed medical care because of persistent lower urinary tract symptoms. He complained of urge incontinence and urination frequency. Decrease of functional bladder capacity was noticed in a frequency volume chart. After consulting with our neurologist, acute transverse myelitis was diagnosed from imaging and neurological findings. Pressure flow study (PFS)demonstrated detrusor overactive during the filling phase and insufficient contractility during the voiding phase. We reached the diagnosis of detrusor hyperactivity with impaired contractility (DHIC). We did not introduce clean intermittent catheterization but used the mirabegron instead. Although storage symptoms did not improve on the mirabegron monotherapy, the symptoms improved by solifenacin added. There is a possibility that combination therapy with mirabegron and solifenacin is effective for DHIC.

We evaluated the impact of tumor shrinkage (TS) induced by molecular targeted therapy as the first-line systemic therapy on the survival of patients with metastatic renal cell carcinoma (mRCC). A total of 67 patients with mRCC who received first-line molecular targeted therapy were included in this study. Sixty patients were evaluable by response evaluation criteria in solid tumors. Patients underwent the first evaluation at 8-12 weeks after the start of the therapy. Twenty patients had TS â§30%, 32 from 30% to -20%, and 8 â¦-20%. The median overall survival periods of patients who achieved TS â§30%, from 30% to -20%, and â¦-20% at first evaluation were 41.0, 35.0, and 11.5 months, respectively. Univariate and multivariate analyses showed that TS ofâ§0%, in addition to negative C-reactive protein and the absence of bone metastasis were good predictors of overall survival. The patients who achieved 0% or more at the initial evaluation had longer survival than those who had no tumor reduction (40.0 months vs 12.0 months, p<0. 001). These findings suggest that early TS affects overall survival in real practice. We should consider alternative therapies for patients who have not achieved tumor reduction at the initial evaluation.

OBJECTIVE: To determine whether cognitive behavioral therapy using a self-check sheet is effective in improving night-time frequency of patients with nocturia. METHODS: We carried out a multicenter, open-labeled, randomized controlled trial in eight institutions. Patients having two or more episodes of nocturia were randomly assigned to either cognitive behavioral therapy with completion of frequency volume charts regularly (cognitive behavioral therapy group) or frequency volume charts regularly alone (frequency volume charts group). The cognitive behavioral therapy checklist was composed of eight items: wake up time/bedtime, mealtime, napping, alcohol/caffeine intake, water intake, salt intake, exercise and taking a bath. A physician explained cognitive behavioral therapy within 5 min using a brief manual. The patients in the cognitive behavioral therapy group filled out the self-check sheet every day. The primary end-point was the difference in night-time frequency based on the International Prostate Symptom Score Q7 at 4 weeks. RESULTS: Of the 100 first-visit patients randomly allocated, 37 in the cognitive behavioral therapy group and 41 in the frequency volume charts group completed the protocol. No difference was observed in the mean ± standard deviation of night-time frequency at 4 weeks between the cognitive behavioral therapy group (2.6 ± 1.0) and the frequency volume charts group (3.1 ± 1.2; P = 0.056). However, when six patients with achievement of cognitive behavioral therapy of <50% were excluded from the analysis, night-time frequency at 4 weeks was significantly lower in the cognitive behavioral therapy group (2.5 ± 1.0) than in the frequency volume charts group (3.1 ± 1.2; P = 0.027). CONCLUSIONS: The efficacy of cognitive behavioral therapy using a self-check sheet for nocturia remains to be shown. However, strictly practicing cognitive behavioral therapy might be beneficial to these patients.

BACKGROUND: We investigated the characteristics and outcomes of patients who underwent open partial nephrectomy (OPN) in the minimally invasive approach era. MATERIALS AND METHODS: We retrospectively reviewed 52 patients (55 cases) who underwent OPN from May 2009 to March 2016. We assessed perioperative change in estimated glomerular filtration rate (eGFR), complications, and oncological outcomes. Tumor complexity was evaluated using the R.E.N.A.L nephrometry score (NS) and the modified NS. RESULTS: Fifteen cases (27%) had imperative indications and 40 (73%) had elective indications. The elective cases were more likely to have adverse tumor complexity based on NS. The perioperative complication rate defined as a Clavien-Dindo grade ≥IIIa was 11%. The rate of postoperative decline in eGFR at 1âmonth, 1âyear, and 2âyears was 22%, 20%, and 21%, respectively. Multivariate analysis revealed that male gender (odds ratio [OR] 11.8, pâ=â0.03), NS ≥9 (OR 13.9, pâ=â0.02), modified NS ≥11 (OR 13.5, pâ=â0.01), and cold ischemic time ≥40 minutes (OR 7.9, pâ=â0.04) were significantly associated with worsening eGFR at 1âyear after surgery. During a median follow-up period of 52âmonths, the 5-year overall survival and recurrence-free survival rates were 93% and 84%, respectively. CONCLUSIONS: OPN is acceptable with regard to oncological outcomes and complications in the minimally invasive surgery era. We propose that OPN should be the preferred approach in cases in which it is technically difficult to preserve maximum renal function via a minimally invasive approach.
RESUMEN
A 72-year-old man was referred to our hospital for examination of a right adrenal tumor incidentally found by computed tomography for close inspection of lumbago. The computed tomography scan and magnetic resonance imaging showed a 51×54×43 mm solid tumor in the right adrenal region. Endocrinological examinations were within normal limits. Because we could not diagnose his condition due to atypical radiographic findings preoperatively and exclude a malignant tumor, laparoscopic right adrenalectomy was performed. The tumor was histologically diagnosed as ganglioneuroma originating from the right adrenal glands.

BACKGROUND: Neuroendocrine (NE) cells may have an impact on the development and initial growth of benign prostatic hyperplasia (BPH) according to previous human studies. METHODS: To explore the relationship of NE cells and BPH development, we compared the density of NE cells and also prostatic weight in spontaneously hypertensive rats (SHR), which develop by aging, and Wistar-Kyoto rats (WKY) as control. The total weights of the epithelium and stroma in the ventral lobes of 8-, 12, 16-, 28- and 56-week-old SHR and WKY were calculated using Image J software. NE cells in the ventral prostatic ducts (VPd) were quantified using immunohistochemical staining for serotonin. RESULTS: Although there was no significant difference in the estimated total weight of the epithelium and stroma in the ventral lobes adjusted by body weight (ES weight) between the two groups at 8, 12 and 16 weeks of age, ES weight was significantly greater in the SHR group than in the WKT group at 28 and 56 weeks. The density of NE cells in the VPd decreased with aging in the WKY group, whereas it was sustained until 16 weeks and then decreased with aging in the SHR group. The difference in the density between the two groups was most marked at 16 weeks of age. CONCLUSION: In the natural history of BPH, NE cells may play an important role in the initial development of BPH because sustained density of NE cells in the VPd precedes the development of prostatic hyperplasia.

OBJECTIVES: To clarify the efficacy of intravesical Bacillus Calmette-Guérin (BCG) instillation for non-muscle invasive bladder (NMIBC) cancer with variant histology, especially glandular differentiation or squamous differentiation. MATERIALS AND METHODS: From May 1991 through June 2016, 53 patients were diagnosed retrospectively as having NMIBC with variant histology. Among these patients, 47 NMIBC patients with squamous differentiation or glandular differentiation were analyzed for this study. The median follow-up interval from diagnosis of NMIBC with variant histology was 28.9 months (1.5-168.8). RESULTS: Of these patients, 38 (80.9%) and 9 (19.1%) were diagnosed as having glandular differentiation and squamous differentiation, respectively. Radical cystectomy was conducted for six (12.8%) immediately after the diagnosis of NMIBC with variant histology. Of the 41 patients with bladder preservation, 20 (48.8%), 3 (7.3%), 3 (7.3%) and 15 (36.6%) underwent BCG, THP, MMC and no additional treatment, respectively. There were significant differences between BCG and other treatments or no additional treatment for recurrence (P = 0.034), progression (P = 0.004) and cancer-specific survival (P = 0.014). CONCLUSION: Overall, our results show that intravesical BCG instillation for variant histology in NMIBC leads to a better prognosis with regard to progression and cause-specific survival than other intravesical treatments or no additional treatment. BCG treatment may also have a clinical benefit for variant histology in non-muscle invasive bladder cancer patients.
