RESUMEN

Background: Only a few reports have currently studied the efficacy of dutasteride in patients with small benign prostatic hyperplasia (BPH). We investigated the efficacy of dutasteride on reducing lower urinary tract symptoms among them. Materials and methods: A total of 81 patients with BPH who completed 52weeks of 0.5?mg dutasteride treatment were enrolled. Each patient filled out the International Prostatic Symptom Score (IPSS) and overactive bladder symptom score (OABSS) at baseline and at the 6- and 12-month follow-up visits. Total testosterone, prostate-specific antigen, adenoma/prostate volume (PV), uroflowmetry analysis, and postvoid residual volume were evaluated at baseline and at the 12-month follow-up visit. The enrolled patients were divided into 2 groups according to PV at baseline. The groups were as follows: Group A (PV ≥ 30 mL) and Group B (PV < 30 mL). Results: Groups A and B had mean PVs of 52.1 and 23.6 mL and mean IPSS scores of 16.7 and 14.4, respectively. Group A had significantly higher OABSS and prostate-specific antigen levels at baseline than Group B, while no significant differences in any other baseline characteristics was observed. After dutasteride treatment, adenoma volume and PV decreased significantly, while testosterone level showed a significant increase in both groups. Group A showed significant improvements in the total IPSS, voiding and storage subscore of the IPSS, OABSS, maximum flow rate, and postvoid residual volume. Group B, on the other hand, also showed significant improvements only in the total IPSS, voiding subscore of the IPSS, and maximum flow rate. Conclusions: The present study suggests a possible beneficial effect of dutasteride treatment on the reduction of lower urinary tract symptoms in patients with small and large BPH. However, the effectiveness of dutasteride was limited compared to patients with large BPH (PV ≥ 30 mL).

RESUMEN

OBJECTIVES: Enfortumab vedotin (EV) is an established pharmacotherapy for metastatic urothelial carcinoma (mUC); however, its adverse events (AEs) cannot be overlooked. The study investigated the efficacy and safety of biweekly EV administration. METHODS: Patients with mUC who received EV at our institution were included in the study. Eligible patients were classified into two groups as follows: those who received EV on a standard schedule (standard group) and those who received EV on a biweekly schedule (biweekly group); the treatment outcomes and AEs between the two groups were compared. RESULTS: Nine and 19 patients were in the standard group and biweekly groups, respectively. The progression-free survival, overall survival, and overall response rate were not significantly different between the two groups. AEs following EV administration, such as decreased appetite (P < .01), pruritus (P < .01), rash maculopapular (P < .01), anemia (P = .04), and liver dysfunction (P = .04), were significantly more frequent in the standard group. Grade 3 or higher AEs, such as pruritus (P = .03) and rash maculopapular (P < .01), were significantly more frequent in the standard group. Furthermore, significantly more patients in the standard group had to be given a reduced dose due to adverse events (P = .02). CONCLUSIONS: Biweekly administration of EV may be safer without compromising therapeutic efficacy than the standard schedule.

RESUMEN

Outflow block of the liver is a life-threatening event after living donor liver transplantation. Herein, we rescued a patient suffering from the outflow block of the remnant left hemiliver caused by bending of the left hepatic vein (LHV) after right hemihepatectomy plus caudate lobectomy combined with resection of the middle hepatic vein (MHV). A metastatic tumor sized 6 cm in the caudate lobe of the liver involving the root of the MHV was found in a 50's year old patient after resection of a right breast cancer eight years ago. Right hemihepatectomy and caudate lobectomy combined with resection of the MHV was performed using a two-stage hepatectomy (partial TIPE ALPPS). On day 1, the total bilirubin value increased to 4.5 mg/dL, and a dynamic computed tomography (CT) scan showed the bent LHV. On the diagnosis of outflow block of the left liver, a self-expandable metallic stent was placed in the LHV using an interventional approach, and the pressure in the LHV decreased from 27 cmH2O to 12 cmH2O. The bilirubin value decreased to 1.2 mg/dL on day 3. Outflow block of the LHV can happen after extended right hemihepatectomy with resection of the MHV. Early diagnosis and interventional stenting treatment can rescue the patient from congestive liver failure.

RESUMEN

To separate the contributions of paramagnetic and diamagnetic sources within a voxel, a magnetic susceptibility source separation method based solely on gradient-echo data has been developed. To measure the opposing susceptibility sources more accurately, we propose a novel single-orientation quantitative susceptibility mapping method with adaptive relaxometric constant estimation (QSM-ARCS) for susceptibility source separation. Moreover, opposing susceptibilities and their anisotropic effects were determined in healthy volunteers in the white matter. Multiple spoiled gradient echo and diffusion tensor imaging of ten healthy volunteers was obtained using a 3 T magnetic resonance scanner. After the opposing susceptibility and fractional anisotropy (FA) maps had been reconstructed, the parametric maps were spatially normalized. To evaluate the agreements of QSM-ARCS against the susceptibility source separation method using R2 and R2* maps (χ-separation) by Bland-Altman plots, the opposing susceptibility values were measured using white and deep gray matter atlases. We then evaluated the relationships between the opposing susceptibilities and FAs in the white matter and used a field-to-fiber angle to assess the fiber orientation dependencies of the opposing susceptibilities. The susceptibility maps in QSM-ARCS were successfully reconstructed without large artifacts. In the Bland-Altman analyses, the opposing QSM-ARCS susceptibility values excellently agreed with the χ-separation maps. Significant inverse and proportional correlations were observed between FA and the negative and positive susceptibilities estimated by QSM-ARCS. The fiber orientation dependencies of the negative susceptibility represented a nonmonotonic feature. Conversely, the positive susceptibility increased linearly with the fiber angle with respect to the B0 field. The QSM-ARCS could accurately estimate the opposing susceptibilities, which were identical values of χ-separation, even using gradient echo alone. The opposing susceptibilities might offer direct biomarkers for assessment of the myelin and iron content in glial cells and, through the underlying magnetic sources, provide biologic insights toward clinical transition.

RESUMEN

OBJECTIVE: Intraoperative hypotension remains a serious adverse event of photodynamic diagnosis-assisted transurethral resection of bladder tumor with oral administration of 5-aminolevulinic acid. We conducted a re-analysis of perioperative hypotension in photodynamic diagnosis-assisted transurethral resection of the bladder tumor with oral 5-aminolevulinic acid to ascertain its safety. METHODS: A total of 407 cases who underwent transurethral resection of bladder tumors in our institution were reviewed (274 cases for the PDD group with photodynamic diagnosis and 133 for the white light (WL) group without). A classification of hypotension severity was devised to identify risk factors for clinically troublesome hypotension. The distribution of hypotension severity in each of the PDD and WL groups was compared. Additionally, the patient background and perioperative data by hypotension severity were compared only in the PDD group. RESULTS: More patients with moderate and severe hypotension were noted in the PDD group. The renal function was lower with increasing hypotension severity in the PDD group. More patients on general anesthesia were included in the mild and moderate hypotension group, whereas more patients on spinal anesthesia were included in the severe hypotension group. Furthermore, the frequency of side effects other than hypotension tended to increase with hypotension severity. CONCLUSIONS: Renal function impairment and the other adverse effects of 5-aminolevulinic acid may be risk factors for severe hypotension. Mild or moderate hypotension may be caused by general anesthesia and severe hypotension may be caused by spinal anesthesia. To elucidate specific risk factors, further case-control studies are warranted.

RESUMEN

BACKGROUND: The efficacy of intermittent androgen deprivation therapy (ADT) for biochemical recurrence (BCR) after robot-assisted radical prostatectomy (RARP) is unknown, and its usefulness in Japanese practice needs to be investigated. METHODS: We conducted a retrospective analysis of 85 patients who underwent RARP and were selected for intermittent ADT for postoperative recurrence at Kanazawa University Hospital between 2009 and 2019. Intermittent ADT was administered for 2 years. If prostate-specific antigen levels increased post-treatment, intermittent ADT was reinitiated. The median follow-up period was 47 months. RESULTS: The 73 patients had completed the initial course of ADT, and 12 were under initial ADT. The 5-year castration-resistant prostate-cancer-free survival rates, cancer-specific survival, and overall survival were 92.7%, 98.3%, and 94.7%, respectively. A subgroup analysis of 69 patients who completed intermittent ADT was conducted to evaluate the BCR rate following initial ADT. The 5-year BCR-free survival rate was 53.2%. Multivariate analysis identified testosterone ≤ 0.03 ng/mL during ADT as the sole predictor of BCR after ADT. CONCLUSIONS: Salvage intermittent ADT may be an effective treatment option for BCR after RARP. In addition, it would be useful to confirm strong testosterone suppression as a criterion for transition to intermittent therapy.

RESUMEN

Introduction: Low-dose-rate brachytherapy is performed for localized prostate cancer. We report the first case of a bladder stone encompassing the seed migrated into the bladder in a patient treated with low-dose-rate brachytherapy. Case presentation: A man was diagnosed with prostate cancer and underwent low-dose-rate brachytherapy. After 2 months, dysuria occurred, and ultrasonography revealed a needle-shaped high-intensity protruding from the prostate into the bladder. Cystoscopy examination found a seed link connector. With the possibility of natural dissolution of the seed link, careful observation was chosen. However, 16 months later, hematuria occurred, and an X-ray revealed a bladder stone encompassing the seed. Compared with the X-ray right after seeding, the seed located near the right bladder neck had fallen. The seed was removed by transurethral bladder lithotripsy. Conclusion: Seeds should be carefully located within the prostate, otherwise a bladder stone may be formed encompassing the seed.

RESUMEN

PURPOSE: To compare the prognosis and quality of life between radical cystectomy and bladder conservative treatment for muscle invasive bladder cancer in the real world. MATERIALS AND METHODS: Patients treated for muscle invasive bladder cancer without metastases were retrospectively evaluated for overall survival, progression-free survival, and rehospitalization. RESULTS: Of the 141 patients, 62 underwent bladder conservative treatment and 79 underwent radical cystectomy. Patients who underwent radical cystectomy had significantly better progression-free survival (HR: 1.83, 95% CI: 1.12-3.00; p < 0.01) and overall survival (HR: 1.82, 95% CI: 0.99-3.34; p = 0.03) than those who underwent conservative treatment. However, there was no significant difference in prognosis between patients who refused to undergo radical cystectomy and those who underwent. In addition, rehospitalization rates for complications and additional treatment were significantly higher in patients who received conservative treatment (69.3% vs. 34.2%; p < 0.01), and the length of hospital stay was also prolonged compared to patients who received radical cystectomy (26 vs. 9 days; p = 0.03). CONCLUSIONS: Overall, conservative treatment had a significantly poorer prognosis than radical cystectomy, but there was no significant difference in prognosis when comparing patients who refused radical cystectomy and received conservative treatment with those who received radical cystectomy. However, hospitalization rates and length of stay were significantly worse for patients who chose conservative treatment, which may lead to a decline in quality of life.

RESUMEN

The R1 (1/T1) map divided by the T2* map (R1/T2* map) draws attention as a high-resolution myelin-related map. However, both R1 and R2* (1/T2*) values demonstrate anisotropy dependent on the white matter (WM) fiber orientation with respect to the static magnetic (B0) field. Therefore, this study primarily aimed to investigate the comprehensive impact of these angular-dependent anisotropies on the R1/T2* value. This study enrolled 10 healthy human volunteers (age = 25 ± 1.3) on the 3.0 T MRI system. For R1/T2* map calculation, whole brain R1 and T2* maps were repeatedly obtained in three head tilt positions by magnetization-prepared two rapid gradient echoes and multiple spoiled gradient echo sequences, respectively. Afterward, all maps were spatially normalized and registered to the Johns Hopkins University WM atlas. R1/T2*, R1, and R2* values were binned for fiber orientation related to the B0 field, which was estimated from diffusion-weighted echo-planar imaging data with 3° intervals, to investigate angular-dependent anisotropies in vivo. A larger change in the R1/T2* value in the global WM region as a function of fiber orientation with respect to the B0 field was observed compared to the R1 and R2* values alone. The minimum R1/T2* value at the near magic-angle range was 18.86% lower than the maximum value at the perpendicular angle range. Furthermore, R1/T2* values in the corpus callosum tract and the right and left cingulum cingulate gyrus tracts changed among the three head tilt positions due to fiber orientation changes. In conclusion, the R1/T2* value demonstrates distinctive and complicated angular-dependent anisotropy indicating the trends of both R1 and R2* values and may provide supplemental information for detecting slight changes in the microstructure of myelin and axons.

RESUMEN

Bone is a common site of prostate cancer metastasis. Bone turnover markers n-terminal propeptide of type I procollagen (P1NP) and tartrate-resistant acid phosphatase type 5b (TRACP-5b) are highly sensitive to bone remodeling activity. However, their prognostic significance as markers of prostate cancer is unknown. This study retrospectively examined the usefulness of P1NP and TRACP-5b as prognostic biomarkers. Castration-resistant prostate cancer recurrence-free survival (CFS) was estimated using the Kaplan-Meier method. A predictive model for CFS was constructed using multivariate analysis. This study enrolled 255 patients diagnosed with prostate cancer at Kanazawa University Hospital. The median follow-up was 115.1 months. Patients with both high serum P1NP and TRACP-5b levels, defined as having a poor bone turnover category (BTC), had significantly shorter CFS. Multivariate analysis identified Gleason score, metastasis, and BTC poor as predictors for castration resistance in prostate cancer. Using these three factors, a prognostic model was established, categorizing patients into low-risk (no or one factor) and high-risk (two or three factors) groups. In the low-risk group, the median CFS was not reached, contrasting with 19.1 months in the high-risk group (hazard ratio, 32.23, p < 0.001). Combining P1NP and TRACP-5b may better predict castration resistance.

RESUMEN

BACKGROUND: Photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) for nonmuscle-invasive bladder cancer is superior to conventional white-light TURBT for cancer detection. However, when performing PDD-TURBT, cystoscopy findings vary depending on the quality of the endoscopic equipment. In this study, we compared the effects of different types of endoscopic equipment on postoperative outcomes. METHODS: Patients who underwent their first PDD-TURBT at our clinic were selected. Patients on whom PDD-TURBT was performed using endoscopic equipment A were sorted into Group A, and patients on whom PDD-TURBT was performed using equipment S were sorted into Group S. The characteristics, recurrence-free survival (RFS), and recurrence frequency of these patients were retrospectively investigated and compared. The prognostic factors for RFS were also analyzed. RESULTS: A total of 49 patients were included in Group A and 46 in Group S. In Group S, a higher detection rate (8.2% vs. 30.4 %, p < 0.01) of carcinoma in situ (CIS) was noted. RFS tended to be better in Group S (HR 0.63, p = 0.15). The frequency of recurrence also tended to be lower in Group S (4.92 vs. 3.66 per 10,000 person-days, p = 0.08). Furthermore, CIS (HR 0.30, p = 0.04) and Bacillus Calmette-Guerin therapy (HR: 0.26, p = 0.01) were significant favorable prognostic factors for RFS. CONCLUSION: The quality of the endoscopic equipment may influence postoperative recurrence after PDD-TURBT. Higher-quality endoscopic instruments have superior CIS detection capabilities, which can lead to improvements in postoperative outcomes with the appropriate selection of postoperative adjuvant therapy.

RESUMEN

OBJECTIVES: Patients with advanced cancer may develop bacterial infections (BI) as their general condition worsens, but general blood tests often find it difficult to distinguish them from non-bacterial infections (NBI). The present prospective study was undertaken to investigate the effectiveness of serum procalcitonin levels in distinguishing between BI and NBI in patients with advanced urological cancer. METHODS: This study prospectively evaluated patients diagnosed with locally advanced or metastatic or recurrent urological cancer in our department from September 2013 to December 2019. Body temperature was measured in the axilla and the measurement results were recorded. Febrile episodes of ≥38.0°C were analysed, and written patient consent was obtained at the onset of the fever. RESULTS: Of 75 patients enrolled in the present study, 90 febrile episodes were analysed. A total of 34 of 90 febrile episodes were regarded as BI, and the remaining 56 febrile episodes as NBI. The median procalcitonin value was significantly higher in the BI group (p=0.0015), while no significant difference was found between the two groups for white blood cell count and C reactive protein. Additionally, a white blood cell count of less than 1.0×10ˆ9/L resulted in BI in all cases. The procalcitonin receiver operating characteristic area under the curve was 0.710 (95% CI 0.586 to 0.83), excluding cases with white blood cell counts of <1.0 × 103/µL. CONCLUSIONS: Procalcitonin is a rapid and affordable marker for differentiation between BI and NBI in patients with advanced urological cancer.

RESUMEN

Purpose: In irradiating the prostate and pelvic lymph node regions, registration based on bony structures matches the pelvic lymph node regions but not necessarily the prostate position, and it is important to identify factors that influence prostate displacement. Therefore, we investigated factors influencing prostate displacement during volumetric modulated arc therapy after single-fraction high-dose-rate brachytherapy (HDR-BT) for prostate cancer and the trends in displacement for each fraction. Methods and Materials: Seventy patients who underwent pelvic volumetric modulated arc therapy of 46 Gy in the prone position 15 days after 13 Gy HDR-BT were included. Prostate displacement relative to bony structures was calculated using cone beam computed tomography. Systematic error (SE) and random error (RE) were evaluated in the right-left (RL), craniocaudal (CC), and anteroposterior (AP) directions. The association with clinical and anatomic factors on the planning computed tomography or magnetic resonance imaging was analyzed. Prostate volume change (PVC) was defined as the volume change at 2 days after HDR-BT. Displacement trends were individually examined from the first to 23rd fractions. Results: The mean SE in the RL, CC, and AP directions was -0.01 mm, -2.34 mm, and -0.47 mm, respectively. The root mean square of the RE in the RL, CC, and AP directions was 0.44 mm, 1.14 mm, and 1.10 mm, respectively. SE in the CC direction was independently associated with bladder volume (P = .021, t statistic = 2.352) and PVC (P < .001, t statistic = -8.526). SE in the AP direction was independently associated with bladder volume (P = .013, t statistic = -2.553), PVC (P < .001, t statistic = 5.477), and rectal mean area (P = .008, t statistic = 2.743). RE in the CC direction was independently associated with smoking (P = .035). RE in the AP direction was associated with PVC (P = .043). Gradual displacement caudally and posteriorly occurred during the irradiation period. Conclusions: Anatomic characteristics of the bladder, rectum, and prostate predict SE. Smoking and PVC predict RE. In particular, whether PVC is ≥140% affects setting internal margins.

RESUMEN

Background: The current study attempted to elucidate the mechanisms of keishibukuryogan (TJ-25) efficacy by focusing on hormonal and cytokine levels. This is a sub-analysis of serum hormonal and cytokine levels extracted from the single-arm prospective study. Methods: Twenty-five participants were administrated TJ-25 at a dose of 2.5 g three times daily for 12 weeks, and competed for a diary of their hot flashes conditions. Various hormonal and cytokine values, including interleukin (IL)-8 and tumor necrosis factor-α (TNF-α), were measured at the baseline and 12-week visits. The correlation of hot flashes with hormonal and cytokine levels at baseline was investigated. As part of the responder analyses, all participants were divided into two groups based on the median baseline values of all hormones and cytokines at baseline, and the change amounts in strength and frequency of hot flashes from baseline to 12-week visits in both groups were compared. Furthermore, a correlation in change amounts (Δ values) by TJ-25 administration between hot flashes and each parameter was also conducted. Results: Hot flashes intensity was inversely related to estradiol levels (r=-0.433, P=0.019), and frequency was inversely related to progesterone levels (r=-0.415, P=0.025). In the responder analyses, the effectiveness of TJ-25 for hot flash strength increased in the patients with higher levels of TNF-α at baseline (P=0.0372). TJ-25 was more efficient in frequency in the patients with higher levels of IL-8 (P=0.0312). TJ-25 efficacy, on the other hand, was not significantly associated with changes in any hormonal or cytokine levels between the baseline and 12-week visits. However, ΔIL-8 and ΔTNF-α were not significantly correlated with Δstrength and Δfrequency of hot flashes by TJ-25 administration. Conclusions: Hot flashes were inversely correlated with estradiol and progesterone levels. TJ-25 was more effective in patients with higher TNF-α and IL-8 levels, with no significant change in serum levels caused by the treatment. The suggestive mechanism for the effects of keishibukuryogan is that this drug doesn't suppress the production of IL-8 and TNF-α, but may inhibit some actions of these cytokines.

RESUMEN

BACKGROUND/AIM: The percentage of positive cores (PPC) is increasingly recognized as a prognostic factor in prostate cancer. However, the usefulness of PPC for patients undergoing androgen deprivation therapy (ADT) and high-risk group has not been adequately studied. PATIENTS AND METHODS: A retrospective analysis was conducted of 255 patients who underwent prostate biopsy (all-case group). We examined the efficacy of PPC as a prognostic biomarker. RESULTS: Eighty-nine patients were treated with ADT alone (ADT group), and 107 patients were classified as high-risk (high-risk group). The median duration of follow-up was 112.4 months, 85.3 months, and 110.0 months for the all-case, ADT, and high-risk groups, respectively. Patients with PPC >60% had significantly shorter prostate cancer-specific survival (CSS) and castration-resistant prostate cancer-free survival (CFS) in the all-case and ADT groups. In the high-risk group, patients with PPC >60% had shorter CFS but no difference in CSS. Multivariate analysis showed that significant independent predictors of prostate CSS were the presence of metastasis at diagnosis and PPC >60% in the all-case and ADT groups. CONCLUSION: PPC may be a prognostic factor in ADT treated and high-risk prostate patients.

RESUMEN

Background and Aims: Testosterone deficiency is often related to geriatric syndrome including erectile dysfunction, osteo-porosis, depression, cognitive impairment, cardiovascular diseases and frailty. Despite the existence of many studies on short-term exercise and serum testosterone levels, few research have focused on exercise habits from young age and testosterone values in middle-aged male. In this study, we investigated whether belonging to an athletic club from school age could predict serum-free testosterone (FT) levels. Methods: The subjects were 1609 middle-aged male outpatients aged 40 years or older (median: 61 years, interquartile range: 54-69) who visited our hospital. Participants had their FT values measured in the morning hours during the period from December 2007 to June 2009. A questionnaire survey on exercise habits was conducted at the same time as the measurements. The exercise habit questionnaire was created based on whether the patients belonged to an athletic club in (a) elementary school, (b) junior high school, (c) high school, (d) college, (e) adult life, and (f) at the time of the test. Results: There was only one positive response to the questionnaire among 456 patients (28% of total), followed by zero for 358 patients (22% of total). The number of patients with low-testosterone levels (FT < 8.5 pg/mL) according to the Japanese diagnostic criteria for late-onset of hypogonadism was 839 (52.1%). In multivariate analysis, it was shown that with low-testosterone levels (FT < 8.5 pg/mL), age (odds ratio [OR]: 1.065, 95% confidence interval [CI]: 1.052-1.079; p < 0.001), hypertension (OR: 3.489, 95% CI: 2.728-4.462; p < 0.001), type-2 diabetes (OR: 3.035, 95% CI: 2.296-4.01; p < 0.001), and dyslipidemia (OR: 2.039, 95% CI: 1.558-2.668; p < 0.001) were risk factors, and more than two positive responses to the questionnaire (OR: 0.886, 95% CI: 0.802-0.980; p = 0.018) were also a significant independent factor.

RESUMEN

BACKGROUND: Intravesical Bacille Calmette-Guerin (BCG) therapy has been reported to be effective in preventing recurrence and progression in non-muscle invasive bladder cancer. Furthermore, photodynamic diagnosis (PDD)-assisted transurethral resection of bladder tumor (TURBT) improves the accuracy of cancer diagnosis and contributes to lower recurrence rates. The purpose of this study is to investigate whether more tumor resection with PDD-TURBT rather than conventional TURBT before BCG therapy outweighs the benefit of BCG therapy alone. METHODS: Patients who underwent intravesical BCG therapy following TURBT in our institution from 2010 to 2021 were included. They were divided into the following two groups: those who received PDD-TURBT before BCG treatment (PDD + BCG group) and those who received conventional TURBT before BCG treatment (WL + BCG group). The 2-year recurrence-free survival (RFS) and progression-free survival (PFS) of the two groups were retrospectively analyzed and compared. RESULTS: The 2-year RFS was significantly improved in the PDD + BCG group (hazard ratio [HR]: 2.41, 95% confidence interval [CI]: 1.26-4.60; p = 0.025). No significant difference in 2-year PFS was noted between the two groups. Analysis of prognostic factors for RFS showed that PDD-TURBT w We think that this text does not adequately express the meaning that we want to deliver to the reader.as a significant prognostic factor in univariate analysis (HR: 0.41, 95% CI: 0.18-0.92; p = 0.03). CONCLUSION: BCG treatment following PDD-TURBT significantly improved RFS more than BCG therapy following WL-TURBT. More accurate tumor localization and more efficient tumor resection by PDD-TURBT may have a positive impact on subsequent BCG treatments even if the treatment is administered postoperatively.

RESUMEN

AIMS: This study aimed to investigate the postoperative urinary continence rate and incontinence types compared over time between conventional robot-assisted radical prostatectomy (C-RARP) and Retzius-sparing RARP (RS-RARP). METHODS: All 61 cases were selected from the C-RARP and RS-RARP by propensity score matching, and the pad scale, 24-h pad weight test, and International consultation on incontinence questionnaire-short form (ICIQ-SF) were followed-up over time up to 12 months. RESULTS: The probability of urinary continence per pad scale evaluation differed according to how it was defined: the continence rate 12 months after C-RARP and RS-RARP were 94% and 95% for 1 pad/day, 85% and 92% for 1 security pad/day, 61% and 85% for no pad use, respectively, which were all significantly better with RS-RARP. The results of the 24-h pad weight test were significantly better with RS-RARP at both 3 and 12 months, with median C-RARP versus RS-RARP values of 5 versus 1 g and 2 versus 0 g, respectively. In terms of types of urinary incontinence, the rates of postoperative stress urinary incontinence (SUI) increased in both procedures but to a lesser extent in RS-RARP. Other types of urinary incontinence, such as urge incontinence and terminal dribbling, did not differ significantly before and after surgery and between the two procedures. CONCLUSIONS: Postoperative urinary continence was better with RS-RARP than with C-RARP per all follow-up parameters until 12 months postoperatively. Postoperative SUI was significantly lower with RS-RARP than with C-RARP, which was considered the main reason for better postoperative urinary continence with RS-RARP.
