PURPOSE: Chronic radiation cystitis (CRC) develops after radiation therapy and can present with symptoms like urinary frequency, urgency, pelvic pain, and nocturia. We have previously reported that amniotic bladder therapy (ABT) provides symptomatic improvement in refractory CRC patients for up to 3 months. Herein, we evaluated the durability of ABT up to 6 months. MATERIALS AND METHODS: CRC patients recalcitrant to previous treatments received ABT comprised of intra-detrusor injections of 100 mg micronized AM diluted in 10 mL 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder (OAB) Assessment Tool, SF-12 Health Survey) were repeated at pre-op and 2, 4, 8, 12, 16, 20, 24, and 36 weeks post-injection. RESULTS: Five consecutive patients with a mean age of 64.4 ± 20.1 years with a median CRC duration of 10 years were included and followed for 6 months. After ABT, the lower urinary tract symptoms improved as early as 2 weeks and were maintained up to 20 weeks. BPIC significantly improved from 36.6 ± 1.1 at baseline to 12.6 ± 1.5 at 16 weeks and 13.8 ± 2.9 at 20 weeks. At 24 and 36 weeks, the improvement was maintained in four (80%) of the five patients (BPIC = 13.8 ± 1.0). Uroflow assessment showed voiding volume improved two-fold in four of the five patients at 24 weeks compared to baseline. CONCLUSION: Our data suggest that a significant number of CRC patients may have durable benefit after ABT. Despite this, some of them can show symptoms rebound at 24 weeks.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 virus is an international health concern with substantial morbidity and mortality. COVID-associated cystitis (CAC), presents as new onset or exacerbated urinary symptoms, resembling overactive bladder (OAB) symptoms. AIM: To examines the long-term outcomes of patients with CAC in the context of Long COVID. METHODS: A cohort of 350 patients admitted to Detroit Hospitals with COVID-19 between May and December 2020, displaying CAC symptoms following discharge, was prospectively followed. Initial urologic evaluations occurred at 10-14 wk and were repeated at 21-28 mo post-discharge. Symptoms were managed conservatively, employing behavioral modifications and standard OAB medications. Participants completed surveys assessing urinary symptoms and quality of life (QoL) at both time points. The primary outcome was the Urology Care Foundation Overactive Bladder Assessment Tool. RESULTS: 87% of the final cohort (n = 310) reported symptom improvement at 21-28 mo post-discharge. Patients with new onset CAC symptoms showed a median decrease of 9-10 points in OAB and QoL scores, while those with existing symptoms experienced a decrease of 6 points. Overall, 95.4% of patients with new onset symptoms reported symptom improvement at follow-up, contrasting with 60.7% among those with existing symptoms. CONCLUSION: This study presents the first long-term follow-up of adult patients with CAC, revealing a promising prognosis with conservative management measures in the context of Long COVID. These findings provide reassurance to patients regarding symptom resolution and underscore the need for further research into this evolving aspect of COVID-19's impact on urological health.

INTRODUCTION: Chronic radiation cystitis (CRC) can develop between 6 months and 20 years after radiation therapy that presents with symptoms of urinary frequency, urgency, bladder pain, and nocturia. Amniotic membrane (AM) is known to contain pro-regenerative properties and could thereby be a potential therapeutic modality for radiation-induced tissue injury of the bladder. MATERIALS AND METHODS: CRC patients recalcitrant to previous treatments received amniotic bladder therapy (ABT) comprised of intra-detrusor injections of 100 mg micronized AM (Clarix Flo) diluted in 10 mL 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/ Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder (OAB) Assessment Tool, and SF-12 Health Survey) were repeated at preop and 2, 4, 8 and 12 weeks post-injection. RESULTS: Five consecutive female patients aged 64.4 ± 20.1 years with a median CRC disease duration of 10 years were included. After ABT, BPIC-SS scores improved from baseline to 12 weeks (36.6 ± 1.1 to 12.6 ± 3.1) and this was associated with an improvement in ICSI, ICPI, OAB, and SF-12 scores. One patient had an acute urinary tract infection at 2 weeks but was successfully treated with oral antibiotics. No other adverse events related to micronized AM injections were observed. Uroflow assessments showed increases in voided volume for all five patients. CONCLUSIONS: This data provides additional evidence for the potential benefit of ABT in patients with chronic inflammatory conditions of bladder such as CRC.

BACKGROUND: Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by symptomatic frequency and urgency, as well as chronic pelvic pain. Disruption of the urothelial barrier is closely associated with IC/BPS. As amniotic membranes (AM) offer capabilities of wound healing in many other fields of medicine, likewise amniotic bladder therapy (ABT) may offer capability of urothelial healing in IC/BPS. METHODS: Under general anesthesia, 10 consecutive IC/BPS patients received intra-detrusor injections of 100 mg micronized AM (Clarix Flo) diluted in 10 ml 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/ Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder Assessment Tool, and SF-12 Health Survey) were repeated at pre-op and 2, 4, 8 and 12 weeks post-op. RESULTS: Ten females (47.4 ± 14.4 years) who had recalcitrant IC/BPS for 7.8 years (5.2-12.1 years) received injection of micronized AM uneventful in all cases. After treatment, voiding symptoms and bladder pain significantly improved from pre-injection to 3 months. BPIC-SS significantly decreased from 37.4 ± 0.70 at baseline to 12.2 ± 2.90 at 3 months (p < 0.001). This corresponded to a significant improvement in their overall physical and mental quality of life. No adverse events occurred related to micronized AM injections, such as UTIs or acute urinary retention. CONCLUSION: ABT could be an innovative treatment option for IC/BPS patients in terms of improving clinical symptoms based on preliminary outcomes at 3 months. Further studies are warranted to confirm the usefulness of ABT in patients with IC/BPS and to determine the duration of the effect.

PURPOSE: There is scarce literature regarding genitourinary symptoms in COVID-19, especially post-acute disease otherwise known as Long COVID. We identified recovered COVID-19 patients presenting with new or worsening overactive bladder symptoms, known as COVID-19-associated cystitis (CAC). METHODS: We used the American Urological Association Urology Care Foundation Overactive Bladder (OAB) Assessment Tool to screen COVID-19 recovered patients presenting with urological complaints at our urban-located institution from 5/22/2020 to 12/31/2020. Patients 10-14 weeks post-discharge responded to 5 symptom and 4 quality-of-life (QoL) questions. We reported median symptom scores, as well as QoL scores, based on new or worsening urinary symptoms, and by sex. RESULTS: We identified 350 patients with de novo or worsening OAB symptoms 10-14 weeks after hospitalization with COVID-19. The median total OAB symptom score in both men and women was 18. The median total QoL score for both men and women was 19. Patients with worsening OAB symptoms had a median pre-COVID-19 symptom score of 8 (4-10) compared to post-COVID-19 median symptom score of 19 (17-21). Median age was 64.5 (range 47-82). Median hospital length-of-stay was 10 days (range 5-30). CONCLUSION: We report survey-based results of patients suffering from new or worsening OAB symptoms months after their hospitalization from COVID-19. Future studies with larger sample sizes and more extensive testing will hopefully elucidate the specific pathophysiology of OAB symptoms in the context of long COVID so urologists can timely and appropriately treat their patients.

Coronavirus disease 2019 (COVID-19) causes a wide range of symptoms, including several unexpected symptoms such as loss of taste, skin changes, and eye problems. We recently observed patients with documented COVID-19 develop de novo severe genitourinary symptoms, most notably urinary frequency of ≥ 13 episodes/24 h and nocturia ≥ 4 episodes/night. We call these associated urinary symptoms COVID-19 associate cystitis (CAC). COVID-19 severity is associated with inflammation. We collected urine samples from COVID-19 patients, including patients with CAC, and found elevation of proinflammatory cytokines also in the urine. It has been previously shown that patients with urinary incontinence and ulcerative interstitial cystitis/bladder pain syndrome have elevated urinary inflammatory cytokines compared to normal controls. We therefore hypothesize that CAC, with presentation of de novo severe urinary symptoms, can occur in COVID-19 and is caused by increased inflammatory cytokines that are released into the urine and/or expressed in the bladder. The most important implications of our hypothesis are: 1) Physician caring for COVID-19 patients should be aware of COVID-19 associate cystitis (CAC); 2) De novo urinary symptoms should be included in the symptom complex associated with COVID-19; and 3) COVID-19 inflammation may result in bladder dysfunction.

BACKGROUND: To create a predictive nomogram for biochemical failure following primary whole-gland cryoablation of the prostate for localized prostate cancer (LPCa). METHODS: We retrospectively analyzed 2,242 patients from the Cryo On-Line Database (COLD) who were treatment naive and had undergone primary whole gland cryoablation of the prostate for biopsy-confirmed LPCa. Kaplan-Meier (KM) curves estimating 5 year biochemical progression-free survival (bPFS) were generated. Multivariable Cox proportional hazards analysis (CoxPH) was performed in order to construct the nomogram. The nomogram was internally validated using the bootstrap technique. RESULTS: Overall, the KM estimated 5 year bPFS was 72.8%. Stratified by D'Amico risk, The KM estimated 5 year bPFS was 82.6%, 71.1%, and 57.8% for low-, intermediate-, and high-risk groups, respectively. Statistically significant predictors of biochemical outcomes from CoxPH analysis were pre-treatment prostate specific antigen (PTPSA) (P < 0.001), total prostate volume (P = 0.004), clinical stage (P = 0.034), and Gleason score (0.004). A nomogram for predicted 5 year biochemical progression free probability was constructed with a concordance index of 0.652. An online risk calculator was also generated. CONCLUSIONS: To the best of our knowledge, this is the first predictive nomogram for biochemical outcomes after primary whole gland cryoablation of the prostate using socio-demographic, pretreatment, clinical, and prostate biopsy data. Our nomogram and online risk calculator can guide both patients and urologists for shared decision making regarding definitive treatment options.

UNLABELLED: Study Type - Therapy (outcomes research). LEVEL OF EVIDENCE: 2c. What's known on the subject? and What does the study add? Most elderly patient with prostate cancer undergo radiation therapy, but cryoablation has gained popularity. This study demonstrates the safety and efficiency of this new approach. OBJECTIVE: • To report on the largest data set regarding outcomes for whole gland prostate cryoablation as a primary treatment of prostate cancer in older men, which we empirically defined as age >75 years. MATERIALS AND METHODS: • The COLD (Cryo On-Line Data) Registry consists of case report forms with pre- and post-treatment information obtained from patients undergoing prostate cryoablation. • A total of 860 patients were stratified into low-, intermediate- and high-risk groups (D'Amico 2003 risk definitions). • Biochemical disease-free survival (bDFS) was defined according to the traditional American Society for Therapeutic Radiology and Oncology definition (3 increases) and the newer (Phoenix) definition (nadir +2). • Biopsy was performed at physician discretion but most commonly for cause if a patient had an increasing or suspicious prostate-specific antigen level (PSA). RESULTS: • The median age was 79 years (76-91) and the median follow-up was 16 months (4-60). • The 5-year [95% confidence interval (CI)] bDFS for the entire population using ASTRO and Phoenix definitions was 79% (4%) and 62.6% (8.3%), respectively. • Stratified by risk group, 5-year bDFS (ASTRO) was 82.4% (7.9%), 78.3% (5.8%) and 77.6% (7.7%) for low, moderate and high risk, respectively. • Using the Phoenix definition, 5-year bDFS was 74.9%± 15.3%, 61.4%± 13.2% and 58.0%± 11.9% for low-, moderate- and high-risk groups, respectively. • Incontinence was reported in eight patients (0.9%). CONCLUSION: • Whole gland cryoablation in older men maintains oncological efficacy similar to that of younger men without increased morbidity.

Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumor, is a benign unusual vascular lesion thought to arise from an organizing thrombus. Histologically, IPEH is characterized by papillary fronds lined by proliferating endothelium that may mimic angiosarcoma, and therefore the correct diagnosis may prevent unnecessary radical procedures. Involvement of the bladder is extremely rare, with only three cases reported in the literature. We report a case of IPEH arising in the bladder of a patient with history of prostate cancer treated with radiotherapy.

Ewing sarcoma typically presents as a skeletal-based tumor, with rare instances of peripheral primitive neuroectodermal tumor (PNET) arising in the soft tissues. Few examples of organ-based PNETs have been previously described in the literature. These tumors are exceedingly rare as a primary renal neoplasm. To our knowledge, this is the first report documenting a primary extraskeletal Ewing sarcoma of the kidney with thrombus extending into the intrahepatic inferior vena cava thrombus (level III).

PURPOSE: We determined the functional consequences of urinary tract infection in patients with an ileal bladder substitute in terms of urinary continence, post-void residual and urinary retention. MATERIALS AND METHODS: A total of 48 patients with culture documented urinary tract infection (single organism, 10(5) or greater cfu) were retrospectively evaluated before, during and after the infection for changes in continence, post-void residual and urinary retention as well as for resolution of symptomatology after appropriate antibiotic therapy. RESULTS: Of the 48 patients 40 had a single infection while the remaining 8 had multiple urinary tract infection episodes. During daytime 27 of the 44 patients with previously good daytime continence experienced deterioration in their baseline voiding status while infected. Of the 40 patients who were previously continent at night 20 had incontinence while infected. There were 15 patients with documented post-void residual and urinary retention developed in 4 during the urinary tract infection. All patients returned to baseline continence status and reservoir function after appropriate antibiotic treatment based on objective and subjective assessments. CONCLUSIONS: Urinary tract infection may cause urinary incontinence in patients with ileal bladder substitutes. Therefore, when there are complaints of de novo urinary incontinence, a finding of post-void residual or an acute presentation of urinary retention, a urinary tract infection should be excluded. When the urinary tract infection is appropriately treated urinary continence and reservoir function return to their baseline status.

Lymph node status is an important determinant for the management of patients with newly diagnosed prostate cancer. Given the significant limitations of cross-sectional and functional preoperative imaging in the detection of small metastases, pelvic lymph node dissection remains the only reliable staging method in clinically localized prostate cancer. Although lymph node dissection is a well-established form of staging in prostate cancer, controversy remains about indications and the surgical extent of the procedure. Reported practices vary from omitting pelvic lymph node dissection in low-risk disease to routine pelvic lymph node dissection in all radical prostatectomy patients. This review highlights the recent literature concerning pelvic lymphadenectomy in prostate cancer with respect to anatomical extent and oncologic outcome.

PURPOSE: Previous studies show conflicting results of the ability of EMLA (eutectic mixture of local anesthetics) to decrease pain during vasectomy. We examined the effectiveness of EMLA cream to decrease pain in patients undergoing bilateral percutaneous no-scalpel vasectomy. MATERIALS AND METHODS: A prospective study was performed in which 316 patients used EMLA cream (178) or no topical anesthesia (138) before vasectomy. EMLA cream was applied by patients 1 hour before the scheduled time of surgery. Bilateral percutaneous no-scalpel vasectomy was then performed in the 2 groups with local infiltration of 1% lidocaine into the scrotal wall and vasal sheath. Following the procedure patients were asked to rate their associated pain using a visual analog scale. Statistical analysis was performed using the 2-sided Student t test. RESULTS: Mean patient age was similar in the groups with and without EMLA (39.1 and 39.0 years, respectively). No significant difference in mean visual analog pain scores were noted between the EMLA and control groups (21.5 vs 21.0, p = 0.8). CONCLUSIONS: Topical anesthesia with EMLA did not significantly decrease the pain associated with percutaneous vasectomy.

OBJECTIVES: To assess the effect of ileal bladder substitutes with preservation of the ileocecal valve and distal 25 cm of ileum on nephrolithiasis. METHODS: We reviewed a consecutive series of 518 patients (44 women and 474 men) with ileal orthotopic bladder substitution in whom 55 to 65 cm of ileum was resected but with preservation of the ileocecal valve and distal 25 cm of ileum, to determine prevalence of nephrolithiasis as well as bicarbonate, base excess, creatinine levels, and urinary pH at time of stone diagnosis and 2 years before it. RESULTS: Four male patients with a median age of 66 years (range, 50 to 70 years) developed nephrolithiasis after ileal bladder substitute, for a total of five calculi. The prevalence of nephrolithiasis in this retrospective cohort is thus 1% (5 of 518). They developed the calculi after a median follow-up of 8 years (range, 4 to 17 years). The four patients were diagnosed with calculi at 2.3, 3, 10, 10.3, and 14 years after bladder substitute. Two of the stones were uric acid calculi; the remaining three were calcium oxalate. None of our patients were acidotic or had elevated serum creatinines at time of stone formation. Urinary pH determined once in spontaneously voided urine at the time of stone diagnosis was pH 6.0 for the two uric acid calculi and pH 7.0 for the remaining calculi. CONCLUSIONS: The present study demonstrates a low prevalence of calculi in our cohort.

OBJECTIVES: To compare the long-term differences in actuarial biochemical relapse-free survival rates from a contemporary series of patients who underwent radical prostatectomy with and without pelvic lymph node dissection (PLND). METHODS: The records of 806 consecutive radical prostatectomy cases performed from January 1995 to June 1999 were reviewed. The entire subset of patients (n = 336) with low-risk disease, defined by a prostate-specific antigen level of 10 ng/mL or less, biopsy Gleason score of 6 or less, and clinical Stage T1 or T2a, who had not received adjuvant or neoadjuvant therapy were divided into two groups according to whether PLND was performed (PLND group, n = 140) or omitted (no-PLND group, n = 196). A Cox proportional hazards model was used to analyze the effect of demographic, pretreatment, surgical, and pathologic factors on the likelihood of biochemical failure. Biochemical relapse-free survival for each group was estimated by Kaplan-Meier analysis. The median prostate-specific antigen follow-up time for the entire group was 89.0 months, with a similar follow-up for both cohorts (PLND group 94.5 months and no-PLND group 88.0 months, Mann-Whitney U test, P = 0.14). RESULTS: The long-term biochemical relapse-free survival rate for the entire cohort was 86.1% at 10 years. The 10-year actuarial biochemical relapse-free rate for the PLND and no-PLND groups was 83.8% and 87.9%, respectively (log-rank, P = 0.33). On univariate analysis, PLND was not an independent predictor of outcome (Wald, P = 0.33). CONCLUSIONS: The results of our study have shown that the omission of limited PLND in patients with favorable tumor characteristics does not adversely affect biochemical relapse-free survival at 10 years. Such patients can be spared the morbidity and cost of PLND without affecting their chance for cure.

PURPOSE: We compared recurrence patterns and survival of patients with urothelial bladder cancer undergoing radical cystectomy who either had limited or extended pelvic lymph node dissection at 2 institutions between 1987 and 2000. MATERIALS AND METHODS: Two consecutive series of patients treated with radical cystectomy and limited pelvic lymph node dissection (336; Cleveland Clinic) and extended pelvic lymph node dissection (322; University of Bern) were analyzed. All cases were staged N0M0 prior to radical cystectomy, and none were treated with neoadjuvant radiotherapy or chemotherapy. Patients with PTis/pT1 and pT4 disease were excluded from analysis. Pathological characteristics based on the 1997 TNM system and recurrence patterns were determined. RESULTS: The overall lymph node positive rate was 13% for patients with limited and 26% for those who had extended pelvic lymph node dissection. The 5-year recurrence-free survival of patients with lymph node positive disease was 7% for limited and 35% for extended pelvic lymph node dissection. The 5-year recurrence-free survival for pT2pN0 cases was 67% for limited and 77% for extended pelvic lymph node dissection, and the respective percentages for pT3pN0 cases were 23% and 57% (p <0.0001). The 5-year recurrence-free survival for pT2pN0-2 cases was 63% for limited and 71% for extended pelvic lymph node dissection, and for pT3pN0-2 cases the respective figures were 19% and 49% (p <0.0001). Incidence of local and systemic failure correlated closely with pathological stage for both series. CONCLUSIONS: Our data suggest that limited pelvic lymph node dissection is associated with suboptimal staging, poorer outcome for patients with node positive and node negative disease, and a higher rate of local progression. Extended pelvic lymph node dissection allows for more accurate staging and improved survival of patients with nonorgan confined and lymph node positive disease.

OBJECTIVES: To map the primary prostatic lymphatic landing sites using a multimodality technique. METHODS: Thirty-four patients with organ-confined prostate cancer (cT1-cT2; cN0) underwent single-photon emission computed tomography fused with data from computed tomography (SPECT/CT) (n=33) or magnetic resonance imaging (SPECT/MRI) (n=1) 1h after ultrasound-guided intraprostatic injection of technecium (Tc-99m) nanocolloid. The presence of lymph nodes (LNs) containing Tc-99m was confirmed intraoperatively with a gamma probe. A backup extended pelvic lymphadenectomy (PLND) was performed to preclude missed primary lymphatic landing sites. The SPECT/CT/MRI data sets were used to generate a three-dimensional projection of each LN site. RESULTS: A total of 317 LNs (median, 10 per patient; range, 3-19) were detected by SPECT/CT/MRI, 314 of which were confirmed by gamma probe. With an "extended" PLND, two thirds of all primary prostatic lymphatic landing sites are resected compared with only one third with a "limited" PLND. CONCLUSIONS: The multimodality technique presented here enables precise mapping of the primary prostatic lymphatic landing sites. PLND for prostate cancer should include not only the external and obturator regions as well as the portions medial and lateral to the internal iliac vessels, but also the common iliac LNs at least up to the ureteric crossing, thus removing approximately 75% of all nodes potentially harbouring metastasis.

OBJECTIVES: To evaluate the presentation, location and overall survival of pelvic recurrence after radical cystectomy (RC) for transitional cell carcinoma (TCC) of the bladder. PATIENTS AND METHODS: We reviewed a consecutive series of 130 patients who had a limited bilateral pelvic lymph node dissection (PLND) and RC between 1987 and 2000, and who later developed pelvic recurrence. All patients were staged N0M0 before RC and no patient received neoadjuvant radio/chemotherapy. The boundaries of the limited PLND were the pelvic side-wall between the genitofemoral and obturator nerves, and the bifurcation of iliac vessels to the circumflex iliac vein. Pelvic recurrence was defined as a radiographic soft-tissue density of > or = 2 cm below the bifurcation of the aorta. Kaplan-Meier and Cox proportional hazards analyses were used to determine if imaging or symptomatic presentation, age, pT stage, and pN status were predictive of overall survival. RESULTS: The median (range) time from RC to pelvic recurrence was 7.3 (1.2-55.4) months. No patients had concomitant distant metastasis. Of the patients, 61.5% were diagnosed with pelvic recurrence because of symptoms, and 38.5% by surveillance computed tomography (CT). Of the 130 patients, 128 died, with a median survival from the time of pelvic recurrence of 4.9 (0.1-129.3) months. The median overall survival time for pelvic recurrence diagnosed with CT was 21.6 months, vs 10.6 months for symptomatic presentations (P < 0.001). In the uni- and multivariate models, type of presentation (CT vs symptomatic) and pT stage were predictors of overall survival, while age and pN status were not. CONCLUSION: The prognosis of patients with pelvic recurrence after RC for TCC is poor even with subsequent therapy, emphasizing the need for optimum local control at the time of initial treatment.
