Neutrophil-to-lymphocyte ratio predicts progression and recurrence of non–muscle-invasive bladder cancer

OBJECTIVEnNeutrophil-to-lymphocyte ratio (NLR) predicts advanced stage disease and decreased survival in patients undergoing radical cystectomy for urothelial carcinoma of the bladder. The predictive value of NLR in non-muscle-invasive bladder cancer (NMIBC) has not been well studied. We aimed to evaluate whether NLR predicted disease recurrence and progression in NMIBC.nnnMATERIALS AND METHODSnThe medical records of 122 consecutive, newly diagnosed, patients with NMIBC treated with transurethral tumor resection, between the years 2003 and 2010, were reviewed. Patients with hematological malignancies (n = 4) and without preoperative NLR (n = 11) were excluded. Cutoff points for NLR were tested separately for recurrence and progression using the standardized cutoff-finder algorithm. Univariate and multivariate Cox regression analyses were used to evaluate the association between NLR and disease recurrence and progression.nnnRESULTSnThe study cohort comprised 91 men and 16 women at a median age of 68 years. The median NLR was 2.85 (interquartile range: 2-3.9). In total, 68 patients (64%) had an NLR>2.41. Patients with NLR>2.41 were more often men (P = 0.02) and had T1 category tumors (P = 0.034). Analyzed as a continuous variable, higher NLR showed a weak positive association with high tumor grade (R = 0.21, P = 0.028). The median follow-up for patients without disease recurrence was 40 months (interquartile range: 23-51). The estimated 3-year progression-free survival rate in patients with an NLR>2.41 was 61%, compared with 84% in patients with an NLR≤2.41 (P = 0.004). On multivariate analysis, an NLR>2.41 (hazard ratio [HR] = 3.52; 95% CI: 1.33-9.33; P = 0.012) and high-risk tumors compared with low-intermediate-risk tumors (HR = 4.83; 95% CI: 1.31-17.77; P = 0.018), as defined by the European Organization for Research and Treatment of Cancer risk tables, were associated with disease progression. An NLR>2.43 (HR = 1.75; 95% CI: 1.05-2.92; P = 0.032) and treatment with intravesical instillations (HR = 0.49; 95% CI: 0.28-0.85; P = 0.011) were associated with disease recurrence on multivariate analysis.nnnCONCLUSIONSnNLR is an independent predictor of disease progression and recurrence in patients with NMIBC without hematological malignancies. Prospective studies are required to validate the role of NLR as a prognostic marker in NMIBC.

Urinary tract infections in patients with orthotopic neobladder

OBJECTIVEnOrthotopic neobladder urinary diversion is associated with a high rate of infectious complications, especially in the early postoperative period. The aim of the study was to assess the incidence, associated pathogens, and predictors of symptomatic urinary tract infection (UTI) in patients with an orthotopic neobladder.nnnMETHODS AND MATERIALSnThe medical records of 79 patients treated with radical cystectomy and orthotopic neobladder urinary diversion at a tertiary medical center in 2004 to 2012 were reviewed for data pertaining to bacteriuria and symptomatic UTI after hospital discharge. Cumulative incidences of clinical events were assessed with the Kaplan-Meier method. Univariate and multivariate Cox regression models were used to identify clinical predictors of infection.nnnRESULTSnA total of 69 men and 10 women were included in the study cohort. The estimated cumulative rates of symptomatic UTI were 34% at 3 months, 40% at 6 months, and 43% at 12 months. New events of symptomatic UTI occurred in 36% of the patients during the first 3 postoperative months, but only in 10% at 3 to 6 months and 8% at 6 to 12 months. Common pathogens were Pseudomonas aeruginosa (24%) and Escherichia coli (24%); 78% of bacterial pathogens were susceptible to amikacin. On multivariate analysis, there was no effect of age, gender, intermittent catheterization, bowel segment used for reconstruction, or perioperative chemotherapy on rates of UTI.nnnCONCLUSIONSnSymptomatic UTI is a common complication after neobladder reconstruction, usually occurring within the first 3 months of surgery. P. aeruginosa infection is common. Inpatient empirical treatment with amikacin is recommended in this setting.

Testicular torsion in the first year of life--characteristics and treatment outcome.

OBJECTIVEnTo review the characteristics and treatment outcome of testicular torsion in infants, aged 1 month to 1 year, and compare them with those seen in neonates.nnnMETHODSnThe study group included 30 patients aged younger than 1 year who were treated for testicular torsion at a tertiary pediatric medical center between 1993 and 2012. Medical records were retrospectively reviewed for clinical characteristics and treatment outcome. Findings were compared between patients who presented before age 1 month (neonate group, n = 17) or later (infant group, n = 13).nnnRESULTSnThe common clinical presentation in the neonate group was a solid, nontender scrotal mass apparent in 13 of 17 patients (76%). In the infant group, 11 of 13 patients (85%) presented with restlessness and 12 of 13 (92%) with a tender scrotal or inguinal mass. Torsion of an undescended testis was significantly more prevalent in infants, 7 of 13 (54%), than neonates, 1 of 17 (6%; P = .009). Although extravaginal torsion was documented in 5 of 6 neonates (83%), 8 of 9 infants (89%) had an intravaginal torsion (P = .011). Orchiectomy was performed in 14 of 17 neonates (82%) and 6 of 13 infants (46%; P = .056). Of the 29 patients with follow-up data, testicular salvage was documented in 1 of 17 neonates (6%) and 2 of 12 infants (17%), at a minimum follow-up of 5 months (P = .55).nnnCONCLUSIONnTesticular torsion in the first year of life is a diverse condition. Although neonatal torsions were predominantly extravaginal, infantile torsions were mostly intravaginal, involving undescendent testes in more than half of the cases. Despite fewer orchiectomies performed on the infant group, testicular salvage rates in both groups were similarly low.

Urinary Retention in Children

OBJECTIVEnTo describe the causes and outcome of urinary retention in children and assess its prevalence by gender and age.nnnMETHODSnThe medical records of all children (aged <18 years) who presented to the emergency room with acute urinary retention from 2000 to 2012 were reviewed. Patients with postoperative urinary retention, a known neurologic disorder, and neonates were excluded. Data were collected on patient demographics and cause, treatment, and outcome of the urinary retention. Findings were evaluated and compared by age and gender.nnnRESULTSnThe study group comprised 42 boys (75%) and 14 girls (25%). Median follow-up time was 25 months. Causes of urinary retention were mechanical obstruction in 14 patients (25%), infection or inflammation in 10 (18%), fecal impaction in 7 (13%), neurologic disorders in 6 (11%), gynecologic disorders in 4 (7%), and behavioral processes in 3 patients (5%); 12 patients (21%) were idiopathic. All patients with mechanical obstruction were boys, of whom 5 had a pelvic tumor. Age distribution was bimodal: 29% of the events occurred between ages 3 and 5 years, and 32%, between ages 10 and 13 years. Fifteen children underwent surgery. Three children required continuous catheterization during follow-up.nnnCONCLUSIONnUrinary retention in children is characterized by a variable etiology and bimodal age distribution. The high rate of severe underlying disease is noteworthy and should alert physicians to the importance of a prompt, comprehensive, primary evaluation of this patient population in a hospital setting to initiate appropriate treatment and avoid complications.

Orthotopic neobladder vs. ileal conduit urinary diversion: A long-term quality-of-life comparison

PURPOSEnThe optimal form of urinary diversion following radical cystectomy remains controversial. We sought to compare the long-term health-related quality-of-life outcomes between patients with orthotopic neobladder and ileal conduit diversion (ICD).nnnPATIENTS AND METHODSnWe enrolled 95 patients following radical cystectomy and ICD (n = 49) or orthotopic neobladder reconstruction (ONR) (n = 46), with a minimum interval of 1 year from surgery. All patients completed the Bladder Cancer Index questionnaire, assessing their urinary, bowel, and sexual function, and bother scores.nnnRESULTSnPatients treated with ONR were generally younger and healthier compared with those who underwent ICD (P<0.01). Sex, marital status, disease status at the time of enrollment, and mean duration elapsing from surgery to interview were similar between the subgroups. Better functional scores in favor of ICD were recorded in the urinary domain (P<0.01), whereas the corresponding bother scores were roughly identical in both groups. Conversely, although higher functional scores were recorded in the sexual domain of patients with ONR (P<0.01), the corresponding bother scores in this group were lower compared with their counterparts with ICD (53.2 vs. 65.3; P<0.05). As patients grew older they were more likely to report on better urinary function and worse sexual function, but were less likely to be bothered by the decline in sexual function.nnnCONCLUSIONSnOur study suggests that the bother resulting from urinary incontinence and the risk of sexual dysfunction be highlighted to those electing for neobladder reconstruction, whereas patients preferring conduit diversion should be reassured that their expected quality of life is not compromised.

Low‐dose oral desmopressin for treatment of nocturia and nocturnal enuresis in patients after radical cystectomy and orthotopic urinary diversion

To assess the effect of oral desmopressin on nocturia and nocturnal enuresis in patients after orthotopic neobladder reconstruction.

Missed Torsion of the Spermatic Cord: A Common yet Underreported Event.

OBJECTIVEnTo describe the incidence of missed diagnosis and delayed presentation in children with testicular torsion, and to identify associated risk factors.nnnMATERIALS AND METHODSnThe medical records of all children over 1 month of age diagnosed with testicular torsion between 2008 and 2014 were reviewed. Data pertaining to patient characteristics and treatment outcome were collected. Orchiectomy was categorized as caused by either delayed presentation or missed diagnosis. Logistic regression analyses were used to evaluate the association between patient characteristics and treatment outcome.nnnRESULTSnThe study cohort included 100 children, 40 of whom underwent orchiectomy. Twenty-eight patients arrived with delayed presentation, and 12 were incorrectly diagnosed. On univariable logistic regression analyses, young age, long duration of pain, and prior community clinic examination were significantly associated with orchiectomy. Similarly, these variables were associated with delayed presentation and missed diagnosis when compared with the orchiopexy group. On multivariable analysis, young age and long duration of pain remained significant predictors of orchiectomy. Doppler ultrasound was performed in 70 patients; 7 of 70 ultrasounds were incorrectly diagnosed. Young age was associated with missed sonographic diagnosis, whereas ultrasound performer (senior radiologist vs resident) and time of the day were not.nnnCONCLUSIONnMissed diagnosis may account for up to 12% of orchiectomy cases. Younger age and prior community clinic examination increase the risk of incorrect diagnosis. Doppler ultrasound should be used with discretion and its results interpreted cautiously.

Presence of detrusor muscle in bladder tumor specimens--predictors and effect on outcome as a measure of resection quality.

OBJECTIVESnTo identify predictors of the absence of detrusor muscle in bladder tumor specimens and analyze its effect on clinical outcome as an indicator of resection quality.nnnMETHODSnThe bladder cancer database of a tertiary medical center was queried for patients who underwent complete transurethral resection of bladder tumor (TURBT) between 2008 and 2009. Study end points were absence of detrusor muscle in the surgical specimen and its association with disease recurrence/progression.nnnRESULTSnDetrusor muscle in the surgical specimen was found in 265 of the 332 study patients (79%). The likelihood of finding muscle increased with higher clinical stage (Odds Ratio [OR]-1.8), higher tumor grade (OR-3), larger tumor size (OR-3.2), multifocal disease (OR-1.7), and nonpapillary morphology (OR-2.3). History of bladder cancer, surgeons experience, and tumor location in the bladder had no effect. In the whole study population, neither tumor recurrence nor disease progression was associated with absence of detrusor muscle. In patients with T1 tumors, absence of detrusor muscle in the specimen was associated with higher early recurrence rate but not worse long-term outcome.nnnCONCLUSIONSnAbsence of detrusor muscle in TURBT specimens is not determined by the technical difficulty of the procedure or surgical experience. Surgeons are more prone to obtain deep muscle in large, nonpapillary-appearing tumors, likely reflecting efforts to attain accurate staging in these cases. The presence or absence of detrusor muscle may serve as a surrogate of resection quality in patients with T1 tumors, but its general applicability to the overall population of patients undergoing TURBT remains questionable.

Urinary Tract Infections After Urinary Diversion—Different Occurrence Patterns in Patients With Ileal Conduit and Orthotopic Neobladder

OBJECTIVEnTo compare the incidence rate of urinary tract infections (UTIs) and associated pathogens between patients with ileal conduit and patients with orthotopic neobladder urinary diversion.nnnPATIENTS AND METHODSnThe medical records of 179 patients treated with radical cystectomy between 2006 and 2011 were reviewed and data pertaining to postoperative UTI were collected. UTI incidence was reported at 3 months intervals and compared by diversion type. Preoperative predictors of UTI were evaluated with Cox regression analyses.nnnRESULTSnThe study cohort included 130 patients with ileal conduit and 49 patients with orthotopic neobladder. Patients with a neobladder were younger (Pu2009<.001). Median follow-up was 38 months (IQR [interquartile range], 11-63). Median time from surgery to first infection was 1.5 months (IQR, 1-12.5) for patients with a neobladder and 11 months (IQR, 2.5-27) for patients with a conduit (Pu2009=u2009.04). During the first 3 months after surgery, 29% of the patients with a neobladder and 8% of the patients with ileal conduit had a UTI episode (Pu2009=u2009.001). Rates of UTI did not differ during subsequent follow-up. Diversion type was not associated with UTI on multivariable analysis. Escherichia coli was the most common pathogen in patients with a conduit (58%), and Klebsiella spp. in patients with a neobladder (29%).nnnCONCLUSIONnThe risk of UTI is significantly higher in patients with a neobladder during the first 3 months after surgery and comparable to patients with ileal conduit during subsequent follow-up. These findings may facilitate preoperative counseling regarding the expected risk of UTI after urinary diversion.
