Clinical safety and efficacy of microwave ablation for small renal masses

ABSTRACT Purpose: CT-guided MWA is a safe and effective tool that should be utilized in the treatment of small renal masses (SRMs). We aim to clarify the utility of CT-guided MWA by examining patient outcomes such as recurrence, treatment success, changes in renal function, and complications. Methods: A retrospective review of consecutive patients with SRMs who underwent same day renal mass biopsy (RMB) and CT-guided MWA between 2015 and 2022 was performed. Treatment safety was assessed by 30-day complications according to the Clavien-Dindo system and change in eGFR >30 days post-procedure. Treatment efficacy was defined by local recurrence and incomplete treatment rates and calculated using the Kaplan-Meier method. Results: A total of 108 renal masses were found in 104 patients. The overall complication rate was 7.4% (8/108), of which 4 were major complications (3.7%). For those with renal function available >30 days post ablation, the median eGFR was 47.2 (IQR: 36.0, 57), compared to 52.3 (IQR: 43.7, 61.5) pre-ablation, p<0.0001. 5-year local recurrence free survival was 86%. Among those with biopsy proven malignancy (n= 66), there were five local recurrences (7.54%) occurring at a median of 25.1 months (IQR 19.9, 36.2) and one case (1.5%) of incomplete treatment. Conclusions: As the medical field continues to evolve towards less invasive interventions, MWA offers a valuable tool in the management of renal masses. With low major complication and recurrence rates, our findings support the utility of CT-guided MWA as a tool for treatment of SRMs.

A nomogram model for the occurrence of bladder spasm after TURP in patients with prostate enlargement based on serum prostacyclin and 5-hydroxytryptamine and clinical characteristics.

OBJECTIVE: With the development of analytical methods, mathematical models based on humoral biomarkers have become more widely used in the medical field. This study aims to investigate the risk factors associated with the occurrence of bladder spasm after transurethral resection of the prostate (TURP) in patients with prostate enlargement, and then construct a nomogram model. MATERIALS AND METHODS: Two hundred and forty-two patients with prostate enlargement who underwent TURP were included. Patients were divided into Spasm group (n=65) and non-spasm group (n=177) according to whether they had bladder spasm after surgery. Serum prostacyclin (PGI2) and 5-hydroxytryptamine (5-HT) levels were measured by enzyme-linked immunoassay. Univariate and multivariate logistic regression were used to analyze the risk factors. RESULTS: Postoperative serum PGI2 and 5-HT levels were higher in patients in the Spasm group compared with the Non-spasm group (P<0.05). Preoperative anxiety, drainage tube obstruction, and elevated postoperative levels of PGI2 and 5-HT were independent risk factors for bladder spasm after TURP (P<0.05). The C-index of the model was 0.978 (0.959-0.997), with a χ2 = 4.438 (p = 0.816) for Hosmer-Lemeshow goodness-of-fit test. The ROC curve to assess the discrimination of the nomogram model showed an AUC of 0.978 (0.959-0.997). CONCLUSION: Preoperative anxiety, drainage tube obstruction, and elevated postoperative serum PGI2 and 5-HT levels are independent risk factors for bladder spasm after TURP. The nomogram model based on the aforementioned independent risk factors had good discrimination and predictive abilities, which may provide a high guidance value for predicting the occurrence of bladder spasm in clinical practice.

Functional and safety outcomes after benign prostatic enlargement surgeries in men with detrusor underactivity compared with normal detrusor contractility: Systematic review and meta-analysis.

INTRODUCTION: Men with detrusor underactivity (DUA) and concomitant bladder outlet obstruction (BOO) due to benign prostatic enlargement (BPE) may present poorer functional outcomes after surgical desobstruction. This study aimed to evaluate the safety and efficacy of BPE surgery in men with DUA compared with those with normal detrusor contractility (NC). MATERIALS AND METHODS: This review was performed according to the 2020 PRISMA framework. A comprehensive literature search was performed until May 7, 2023, using MEDLINE, EMBASE, and Cochrane Database. No date limits were imposed. Only comparative studies were accepted. The primary endpoint was to assess if there was any difference in short- and long-term functional outcomes after BPE surgery in men with DUA and NC. The secondary endpoint was to evaluate the differences in perioperative outcomes and postoperative complications between the two groups. Meta-analysis was performed using Review Manager (RevMan) software. RESULTS: There were 5 prospective nonrandomized studies and 12 retrospective studies, including 1701 DUA and 1993 NC patients. Regarding surgical procedures, there were eight TURP (transurethral resection of the prostate) studies, four GreenLight PVP (photoselective vaporization of the prostate) studies, two HoLEP (Holmium laser enucleation of the prostate) studies, one GreenLight PVP/HoLEP study, one Holmium laser incision of the prostate study, and one study did not report the type of surgery. We did not find a statistically significant difference between the two groups in terms of perioperative outcomes, including postoperative catheterization time, hospitalization time, urinary retention, need to recatheterization, transfusion rate, or urinary tract infections. Also, we found no significant differences in long-term complications, such as bladder neck stenosis or urethral stenosis. Posttreatment bladder recatheterization and retreatment rate for BPE regrowth could not be evaluated properly, because only one study reported these findings. When we analyzed functional outcomes at 3 months, those with NC had lower International Prostatic Symptom Score (IPSS), lower quality-of-life (QoL) score, better maximum flow rate (Qmax), and lower post-voiding residual (PVR) of urine. These results were maintained at 6 months postoperatively, with exception of PVR that showed no difference. However, at 12 and more than 12 months the functional outcomes became similar regarding IPSS and QoL. There were few data about Qmax and PVR at longer follow-up. CONCLUSION: In this meta-analysis, data suggest that BOO surgical treatment in patients with concomitant BPE and DUA appears to be safe. Despite patients with DUA may present worse functional outcomes in the short postoperative term compared with the NC population, IPSS and QoL scores become comparable again after a longer follow-up period after surgery.

Comparison of bipolar radiofrequency thermotherapy and transurethral prostate resection in treatment of benign prostate hyperplasia.

OBJECTIVES: Lower urinary tract symptoms due to benign prostatic hyperplasia in men increase with aging. Risks related to anesthesia and surgery have led a search for alternative treatments. Bipolar radiofrequency (RF) thermotherapy is one of the methods adopted in patients with high surgical risks. The aim of this study is to compare the effect of bipolar RF thermotherapy and transurethral resection of the prostate (TURP) methods on voiding symptoms and on post-operative complication rates especially in patients carrying high surgical risks. METHODS: Pre-operative, post-operative 1st and 6th month International Prostate Symptom Score (IPSS), Qmax, quality of life, prostate volumes, and postoperative complications of the patients underwent TURP and RF for benign prostatic hyperplasia (BPH) were compared. RESULTS: In the RF group, the pre-operative median IPSS was 30, prostate volume 41.5 cc, post-void residual (PVR) 80 ml, and Qmax is 5.85 ml/s.; In the TURP group, these were 29, 40 cc, 85 ml, and 5.3 ml/sec, respectively. In the Bipolar RF group, post-operative 1st- and 6th-month median values were IPSS 18, 21; prostate volume 40, 40; PVR 40, 35; Qmax 10.9, 9.15 and in the TURP group IPSS 9, 8; prostate volume 20, 20; PVR 30, 10; Qmax 17.25, 19.1, respectively. CONCLUSION: Bipolar RF thermotherapy is an applicable treatment method for BPH patients with high surgical risks.

El objetivo de este estudio es comparar el efecto de la termoterapia de radiofrecuencia bipolar y los métodos de RTUP en los síntomas de vaciado y en las tasas de complicaciones posoperatorias, especialmente en pacientes con alto riesgo quirúrgico. MÉTODOS: Se compararon el IPSS, el Qmax, la calidad de vida, los volúmenes de próstata y las complicaciones posoperatorias de los pacientes sometidos a RTUP y RF para la HBP preoperatorios, posoperatorios al primer y sexto mes. RESULTADOS: En el grupo de RF, la mediana preoperatoria del IPSS fue de 30, el volumen prostático de 41.5 cc, el PVR de 80 ml y el Qmax de 5.85 ml/seg.; En el grupo RTUP estos fueron 29, 40 cc, 85 ml y 5.3 ml/seg, respectivamente. En el grupo de RF bipolar, los valores medianos postoperatorios del primer y sexto mes fueron IPSS 18, 21; volumen de próstata 40, 40; PVR 40, 35; Qmax 10.9, 9.15 y en el grupo TURP IPSS 9, 8; volumen de próstata 20, 20; PVR 30, 10; Qmax 17.25, 19.1, respectivamente. CONCLUSIÓN: La termoterapia de RF bipolar es un método de tratamiento aplicable para pacientes con HPB con alto riesgo quirúrgico.

Predictors of early catheter replacement after HoLEP. Results from a high-volume laser center

ABSTRACT Introduction: The aim of the study was to investigate clinical and surgical factors associated with early catheter replacement in patients treated with Holmium Laser Enucleation of the Prostate (HoLEP). Materials and Methods: Data of patients treated with HoLEP at our Institution by a single surgeon from March 2017 to January 2021 were collected. Preoperative variables, including non-invasive uroflowmetry and abdominal ultrasonography (US), were recorded. Bladder wall modifications (BWM) at preoperative US were defined as the presence of single or multiple bladder diverticula or bladder wall thickening ≥5 mm. Clinical symptoms were assessed using validated questionnaires. Only events occurred within the first week after catheter removal were considered. Results: Overall, 305 patients were included, of which 46 (15.1%) experienced early catheter replacement. Maintenance of anticoagulants/antiplatelets (AC/AP) therapy at surgery (p=0.001), indwelling urinary catheter (p=0.02) and the presence of BWM (p=0.001) were more frequently reported in patients needing postoperative re-catheterization. Intraoperative complications (p=0.02) and median lasing time (p=0.02) were significantly higher in this group. At univariate analysis, indwelling urinary catheter (p=0.02), BWM (p=0.01), ongoing AC/AP therapy (p=0.01) and intraoperative complications (p=0.01) were significantly associated with early catheter replacement. At multivariate analysis, indwelling urinary catheter (OR: 1.28; p=0.02), BWM (OR: 2.87; p=0.001), and AC/AP therapy (OR: 2.21; p=0.01) were confirmed as independent predictors of catheter replacement. Conclusions: In our experience the presence of indwelling urinary catheter before surgery, BWM and the maintenance of AC/AP therapy were shown to be independent predictors of early catheter replacement after HoLEP.

Adequate Mentorship Program for Holmium Laser Enucleation of the Prostate (HoLEP) Leads to Satisfactory Short-Term Outcomes in the Early Learning Curve of Young Urologists: First-Year Outcomes of a Newly Established Mentorship Training in Mexico.

Introduction Benign prostatic hyperplasia (BPH) is one of the most common causes of lower urinary tract symptoms in men. Holmium Laser Enucleation of the Prostate (HoLEP) has been recommended by international guidelines as an alternative to transurethral resection of the prostate (TURP). HoLEP's learning curve and the lack of adequate mentorship remains an obstacle for the worldwide adoption of this technique. Objective To report the first-year learning curve of a newly established mentorship program in young urologists without any previous HoLEP experience. Methods We report a cohort of patients with BPH, with prostate size ≥70 grams, treated with HoLEP, analyzed for perioperative data and complications, and short-term postoperative complications and functional outcomes, at three and six months after surgery. Results A total of 47 patients were managed with HoLEP. Mean total operative time was 149.8 ± 42.9 minutes. We experienced five (10.6%) intraoperative complications, including one intravesical resection of the prostate with bipolar energy, three conversions to TURP and one conversion to open prostatectomy. We experienced four postoperative complications, all of them Clavien-Dindo ≤2. Median International Prostate Symptom Score (IPSS) decrease at six months was -17 points from baseline. Mean post-void residual volume and prostate-specific antigen significantly decreased by the third postoperative month. Multiple linear regression showed that prostate size is directly related to increased surgical time during the early learning curve. Discussion Our experience adequately reflects the importance of HoLEP mentorship in young urologists seeking training in this technique. Both surgeons had perioperative and postoperative outcomes deemed satisfactory based on previously published learning curves. Conclusions HoLEP is a technically difficult procedure, however, adequate mentorship leads to satisfying short-term outcomes since the early stages of the learning curve in young urologists with no previous training on this technique.

CONCLUSIONS: In our experience the presence of indwelling urinary catheter before surgery, BWM and the maintenance of AC/AP therapy were shown to be independent predictors of early catheter replacement after HoLEP.

Localized genitourinary tract Aspergillus infection in an immunocompetent patient: Bladder and epidydimal aspergillosis.

Invasive bladder Aspergillosis has only been reported in six publications so far. A 74-year-old male, presented to the emergency department with fever, abdominal pain, and right testicular enlargement. Abdominal computed tomography concluded a bladder tumor and testicular ultrasound reported right epididymitis. Cystoscopy showed a bladder fungal mass, which was extracted with cystotomy. Pathological findings reported Aspergillus species. The patient was successfully treated with 4-week oral Isovuconazole. The first bladder Aspergillosis was published in 1978. The most recent case was published in 2020. Aspergillosis infection is extremely rare disease, treatment with Isavuconazole is efficient.

Benign prostatic hyperplasia surgical treatment trends in the Public Health System in São Paulo, Brazil

ABSTRACT Objective To describe and compare the number of surgeries, mortality rate, length of hospital stay, and costs of transurethral resection of the prostate and open prostatectomy for the treatment of benign prostatic hyperplasia, between 2008 and 2018, in the Public Health System in São Paulo, Brazil. Methods Ecological and retrospective study using data from the informatics department of the Brazilian Public Health System database. Procedure codes were "open prostatectomy" and "transurethral resection of the prostate." The outcomes analyzed were compared between transurethral resection of the prostate and open prostatectomy according to the hospital surgical volume and presence or absence of a residency program. Results A total of 18,874 surgeries were analyzed (77% transurethral resection of the prostate) and overall mortality was not statistically different between procedures. Intermediate and high-volume centers had shorter length of hospital stay than low-volume centers for transurethral resection of the prostate (3.28, 3.02, and 6.58 days, respectively, p=0.01 and p=0.004). Length of hospital stay was also shorter for open prostatectomy in high-volume compared to low-volume centers (4.86 versus 10.76 days, p=0.036). Intrahospital mortality was inversely associated with surgical volume for transurethral resection of the prostate. Centers with residency program had shorter length of hospital stay considering open prostatectomy and less mortality regarding transurethral resection of the prostate. Open prostatectomy was 64% more expensive than transurethral resection of the prostate. Conclusion The findings suggest the importance of investing in specialized centers, which could be potential referral centers for surgical cases.

Monopolar versus bipolar transurethral resection of lateral wall-located bladder cancer under obturator nerve block: a single center prospective randomized study

ABSTRACT Introduction: The aim of the present prospective-randomized study was to compare perioperative outcomes and complications of bipolar and monopolar TURBT for lateral wall-located non-muscle invasive bladder cancers (NMIBC) under obturator nerve block (ONB). Patients and Methods: 80 patients who underwent TURBT for lateral wall-located primary bladder tumors under ONB from March, 2016 to November, 2019 were included in the present study. The patients were randomized equally into two groups; monopolar TUR (M-TURBT) and bipolar TUR (B-TURBT). The primary and secondary outcomes were safety (obturator jerk and bladder perforation) and efficacy (complete tumor resection and sampling of the deep muscle tissue). Results: Obturator jerk was detected in 2 patients (5%) in M-TURBT while obturator jerk was not observed during B-TURBT (p=0.494). Bladder perforation was not observed in both groups. All of the patients underwent complete tumor resection. There was no significant difference in muscle tissue sampling (67.5% vs. 72.5%, p=0.626) and thermal tissue damage rates (12.5% vs. 25%, p=0.201). The majority of complications were low-grade and the differences in Clavien grade 1-3 complications between groups were not statistically significant. Conclusion: In the treatment of lateral-wall located NMIBCs, either M-TURBT or B-TURBT can be safely and effectively performed by combining spinal anesthesia with ONB. Even so, it should be taken into consideration that low-grade postoperative hemorrhagic complications may occur in patients who undergo M-TURBT.

Shedding light on polypragmasy of pain after transurethral prostate surgery procedures: a systematic review and meta-analysis.

PURPOSE AND OBJECTIVE: To evaluate and compare the incidences of post-operative pelvic pain (PPP) in patients undergoing ablation, enucleation and conventional transurethral resection of the prostate (TURP). METHODS: A systematic review and meta-analysis was conducted according to the PRISMA guidelines. Using MEDLINE via PubMed and Cochrane CENTRAL, randomised control trials (RCTs) and observational studies reporting PPP rates post-ablation, enucleation or TURP were identified. The risk of biases (RoB) in RCTs and observation studies were assessed using the Cochrane RoB1.0 tool and the Newcastle-Ottawa Scale, respectively. RESULTS: 62 studies were included for qualitative analysis, while 51 of them reported number of patients with PPP post-intervention. Three observational studies and 13 RCTs compared the rates of PPP in patients undergoing ablation, enucleation or TURP. The most reported types of PPP are dysuria, abdominal pain and irritative symptoms. The pooled incidence of PPP at 1-month follow-up in patients undergoing ablation, enucleation and TURP were 0.15 (95% CI 0.10-0.22), 0.09 (95% CI 0.04-0.19 and 0.10 (95% CI 0.06-0.15), respectively. PPP is no longer prevalent at 3-months and onwards post-operatively. Ablation is associated with a higher risk of PPP than enucleation (RR 2.19, 95% CI 1.04-4.62) and TURP (RR 2.40, 95% CI 1.03-5.62) in observational studies but not RCTs; and there were no significant differences in the rates of PPP upon comparison of other modalities. CONCLUSION: PPP is common after transurethral benign prostatic hyperplasia surgery. Patients undergoing ablation had a higher rate of post-intervention PPP than those undergoing enucleation and TURP in observational studies.

A prospective randomized study comparing bipolar plasmakinetic transurethral resection of the prostate and monopolar transurethral resection of the prostate for the treatment of Benign Prostatic Hyperplasia: efficacy, sexual function, Quality of Life, and complications

ABSTRACT Objective: To generate high-quality data comparing the clinical efficacy and safety profile between monopolar transurethral resection of the prostate (M-TURP) and bipolar plasmakinetic resection of the prostate (PK-TURP) for benign prostatic hyperplasia (BPH). Materials and Methods: Prospective, randomized, single-blinded study conducted in a tertiary-care public institution (Dec/2014-Aug/2016). Inclusion criteria: prostate of <80g in patients with drug-refractory lower urinary tract symptoms (LUTS), complications derived from BPH, or both. Exclusion criteria: a history of pelvic surgery/radiotherapy, neurogenic bladder dysfunction or documented/suspected prostate carcinoma. Treatment efficacy evaluated at 1, 3, 6 and 12 months. Efficacy outcomes: international prostate symptom score (IPSS), quality-of-life (QoL) score, international index of erectile function-5 (IIEF-5), maximum urinary flow rate (Qmax), postvoid residual urine (PVRU) volume, and prostate volume (PV). Complications and sequelae also assessed. Comparisons performed with parametric/non-parametric tests. Results: Out of the 100 hundred patients, 84 qualified for the analysis (45 M-TURP/39 PK-TURP). No significant differences found in baseline characteristics or operative data, except for a longer operative time in PK-TURP (MD:7.9min; 95%CI:0.13-15.74; p=0.04). No differences found in IPSS, Qmax or PVRU volume. QoL score at 12 months was higher in PK-TURP (MD:0,9points; 95%CI:0.18-1.64; p=0.01). No differences in sexual function, PV, complications or sequelae were found. This study is "rigorous" (Jadadscale) and has a low risk of bias (Cochrane-Handbook). Conclusions: Based on this controlled trial, there is not significant variation in effectiveness and safety between M-TURP and PK-TURP for the treatment of BPH. The small difference in QoL between PK-TURP and M-TURP at the one-year follow-up is not perceivable by the patients and, therefore, not clinically relevant.

Intrasphincteric anastomotic urethroplasty allows preservation of continence in men with bulbomembranous urethral strictures following benign prostatic hyperplasia surgery.

PURPOSE: Injury to the external sphincter during urethroplasty at or near the membranous urethra can result in incontinence in men whose internal sphincter mechanism has been compromised by previous benign prostatic hyperplasia (BPH) surgery. We present outcomes of a novel reconstructive procedure, incorporating a recent anatomic discovery revealing a connective tissue sheath between the external sphincter and membranous urethra, which provides a surgical plane allowing for intrasphincteric bulbo-prostatic urethroplasty (ISBPA) with continence preservation. METHODS: Stricture at or near the membranous urethra after transurethral resection (TURP) or open simple prostatectomy (OSP) was reconstructed with ISBPA. The bulbomembranous junction is approached dorsally with a bulbar artery sparing approach and the external sphincter muscle is carefully reflected, exposing the wall of the membranous urethra. Gentle blunt dissection along this connective tissue plane allows separating the muscle away up to the prostatic apex, where healthy urethra is found for anastomosis. RESULTS: From January 2010 to August 2019, 40 men (18 after TURP and 22 after OSP) underwent ISBPA at a single institution. Mean age was 67 years (54-82). Mean stricture length was 2.6 cm (1-6) with obliterative stricture identified in 10 (25%). At a mean follow-up of 53 months (10-122), 36 men (90%) are free of stricture recurrence and 34 (85%) were completely dry or using one security pad. CONCLUSION: This novel intrasphincteric urethroplasty technique for stricture following BPH surgery is feasible and safe, allowing successful reconstruction with continence preservation in most patients. A larger series and reproduction in other centers is needed.

Recomendaciones: El tipo de abordaje endoscópico se ha convertido en la actualidad en el tratamiento estándar de oro para la mayoría de las patologías del tracto urinario inferior; sin embargo, se requiere realizar más estudios sobre las complicaciones y factores de riesgo relacionados al tiempo de sondaje postquirúrgico para evitar complicaciones en cirugías endourológicas del tracto urinario inferior

ABSTRACT Objective: to determine the recommended post-surgical probing time to avoid complications in endourological surgeries of the lower urinary tract. Materials and methods: an updated bibliographic review was carried out on the recommended post-surgical catheterization time to avoid complications in endou-rological surgeries of the lower urinary tract. Results: An association was found between a longer catheterization time and the occurrence of subsequent complications related to endourological surgeries of the lower urinary tract, with the period of less than 72h being the optimal period for the permanence of the postsurgical urinary catheter in this type of intervention. No risk factors associated with prolonged postoperative probing time were identified. Recom-mendations: The type of endoscopic approach has now become the gold standard treatment for most lower urinary tract pathologies; However, more studies are required on the complications and risk factors related to the time of postoperative catheterization to avoid complications in endourological surgeries of the lower urinary tract

The relation between the storage symptoms before and after transurethral resection of the prostate, analysis of the risk factors and the prevention of the symptoms with solifenacin

ABSTRACT Objective and Hypothesis We aimed to investigate the reasons of storage symptoms ( SS) after transurethral resection of the prostate (TURP). The hypothesis was that a positive correlation would be identified between preoperative and postoperative SS in patients with undergoing TURP and starting early solifenacin treatment in patients with high preoperative SS would be reasonable. In addition, we aimed to analyze multiple other risk factors for post-TURP SS. Materials and Methods A total of 160 patients undergoing TURP were prospectively evaluated and divided into two groups according to their OABS. Those with a score of ≥10 points were Group 1 (G1), and those with <10 points Group 2 (G2). In addition, patients in each group were randomly further divided into two subgroups: those who were started on 5 mg solifenacin succinate in the early postoperative period (G1/G2 A) and those who were not (G1/G2 B). In additions to SS Preop, perop and at the 3rd-month of postoperatively 14 variable were evaluated. The effects of these factors, surgery and the efficacy of an early medical treatment on the postoperative SS were investigated. LUTS were assessed by International Prostate Symptom Score (IPSS) and SS were assessed by sum of IPSS 2, 4 and 7 questionnaires (Storage, S- IPSS). Results Preoperative IPSS and S-IPSS were significantly higher in G1 (p<0.001); there was a significant improvement at IPSS, S-IPSS, QoL score, Qmax, and PVR for all groups after surgery. Only preoperative S-IPSS was found to have significant effect on postoperative SS (p<0.001). There was a significant difference between G1A and G1B but no significant difference between G2A and G2B in terms of SS at postoperatively. In addition to this, prostatic volume was found smaller than non-symptomatic patients in de novo SS patients. Conclusion TURP provides significant improvement in both storage and voiding symptoms. The predictive value of the preoperative S-IPSS on postop SS is significant. These results suggest that 5 mg solifenacin succinate treatment in the early postoperative period may be beneficial for patients with high preoperative SS and may not be beneficial in others. Small prostatic volume may bode ill for postoperative SS in the patients with de novo SS.

Functional capacity as a predictor of postoperative delirium in transurethral resection of prostate patients in Northeast Brazil.

INTRODUCTION: Postoperative delirium (POD) is a common disorder and its frequency varies from 15% to 25% after major elective surgery. There are few data on the incidence of POD in Brazil. Here, we sought to assess the incidence of POD following transurethral resection of the prostate (TURP) and to examine precipitating and predisposing factors associated. METHOD: We performed a prospective observational study of elderly male patients undergoing TURP (N=55) in Northeast Brazil. Information on demographic, medical, cognitive and functional characteristics were collected. The participants were followed until hospital discharge. POD was diagnosed by the Confusion Assessment Method. RESULTS: A total of three participants (5.45%) were identified with POD. Episodes of delirium lasted 3±1 days. The study sample consisted of a healthy population. Patients with POD had longer hospital stay and more precipitating factors. The POD group showed statistically significant lower Barthel index score (p<0.001) and higher Pfeffer's Functional Activities Questionnaire scores (p<0.01). CONCLUSION: Loss of functional capacity was associated with POD in a healthy population of elderly patients undergoing TURP.

Non-functional paraganglioma of urinary bladder managed by transurethral resection

ABSTRACT Purpose As a rare bladder tumor, paraganglioma of the urinary bladder (PUB) is frequently misdiagnosed as bladder cancer, particularly for the non-functional type. To date, transurethral resection remains a controversial treatment for non-functional PUB. This study aimed to identify the clinical features, pathological characteristics, prognosis, and safe/effective treatment of non-functional PUB using transurethral resection of the bladder tumor (TURBT). Materials and Methods The clinical records, radiological data, pathological characteristics and follow-up times were retrospectively reviewed in 10 patients with clinically and pathologically proven non-functional PUB in our hospital from January 2008 to November 2016. All patients underwent TURBT treatment. Results The incidence of non-functional PUB in patients with bladder cancer was 0.17%. The mean age at diagnosis was 44.5 ± 13.6 years (range, 29-70 years), and the patient population had a female: male ratio of 3: 2. No patients had excess catecholamine (CA) whilst four patients had painless hematuria. All neoplasms were completely resected via TURBT. The majority of samples were positive for immunohistochemical markers including chromogranin A (CgA) and Synaptophysin (Syn), but were negative for cytokeratins (CKs). Only a single recurrence was observed from the mean follow-up period of 36.4 ± 24.8 months. Conclusion Complete TURBT is a safe and efficient treatment that serves both diagnostic and therapeutic purposes. Histopathological and immunohistochemistry examinations are mandatory for diagnostic confirmation. Long-term follow-up is recommended for patients with non-functional PUB.
