OBJECTIVE: To evaluate the quality of life of patients with interstitial cystitis/bladder pain syndrome (IC/BPS), to compare the difference between IC/BPS and overactive bladder (OAB) pain syndrome, and to explore the related factors affecting the quality of life of IC/BPS patients. METHODS: The demographic data of female outpatients with IC/BPS in Beijing Hospital and other medical centers in China were collected. The quality of life of the patients was investigated by multi-angle questionnaires and compared with the data of OAB patients. According to the influence degree of quality of life, the patients with IC/BPS were divided into mild-moderate group and severe group. RESULTS: In this study, 109 patients with IC/BPS were included. The average age was (46.4±14.3) years and the average course of disease was (39.4±51.6) months. Compared with the OAB patients, the patients in IC/BPS group had a longer average course of disease (P=0.008), a lower proportion of the patients of first visit for the disease (P < 0.001), a higher score of the American Urological Association symptom index (AUA-SI) (P < 0.001), a lower body mass index (BMI) ratio (P=0.016), and a lower incidence of constipation (P=0.006). IC/BPS had the greatest impact on family life, followed by social activity. The score of IC/BPS related symptoms on family life was significantly higher than that of the OAB group (P=0.003). The top three symptoms of the IC/BPS patients were pain (45%), frequency (28%) and urgency (17%). The score of quality of life in the IC/BPS patients was significantly higher than that in the OAB patients (P < 0.001). Caffeine intake (P=0.034) and constipation (P=0.003) might be the factors influencing the quality of life of the patients with IC/BPS. CONCLUSION IC/BPS has a great influence on the quality of life of patients. Caffeine intake and constipation may be related factors affecting the quality of life of patients with IC/BPS. Urologists should recommend changes in diet and lifestyle to reduce symptoms and improve the patients' quality of life.

OBJECTIVETo analyze the incidence and risk factors of hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (HSCT).

METHODSThe medical records of 250 patients undergoing allogeneic HSCT in Peking University Institute of Hematology from Sep. 2003 to Sep. 2005 were analyzed.

RESULTSHC occurred in 72 of the 250 patients within 180 days after transplantation with a cumulative incidence of 28.8% (SE 0.3%). None of early-onset HC was developed in the cohort. The median time of onset was 33 days after HSCT (range 14 - 170 days) and the median duration of HC was 35 days (range 3 -186 days). There were HC of grade I - II in 51/72 cases (70.83%) and of grade III - IV in 21/72 (29.17%). Univariate analysis indicated that age younger than 25, high risk disease, CMV reactivation, ATG usage, graft from MUD or MMRD and GVHD grade IL - IV were associated with the occurrence of HC, while in multiple regression analysis only GVHD grade II - IV (RR = 2.75; 95% CI 1.63 -4.66; P < 0.01) and donor type (RR = 2.60; 95% CL 1.52 - 5.20; P < 0.01) were independent risk factors. Kaplan-Meier survival analysis indicated HC not increasing the mortality (RR = 0.67, 95% CI 0.33 - 1.36).

CONCLUSIONHC post allo-HSCT is a common complication, GVHD grade II - IV and donor type are the independent risk factors.

OBJECTIVETo analyze the risk factors of hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation for beta-thalassemia in children.

METHODSThe clinical records of 30 children with beta-thalassemia undergoing allogeneic hematopoietic stem cell transplantation between December, 2008 and November, 2009 were analyzed.

RESULTSHemorrhagic cystitis occurred in 8 of the 33 patients with an incidence of 24.24%, including 1 with grade I, 6 with grade II and 1 with grade III hemorrhagic cystitis. The median time of hemorrhagic cystitis onset was 22.9 days (range 6-35 days) and the median duration was 11.9 days(range 3-27 days). Univariate analysis indicated that the different types of transplantation and acute graft-versus-host disease affect the occurrence of hemorrhagic cystitis. The children with Allo-PBSCT had higher incidence than those receiving Allo-PBSCT+Allo-UBT and Allo-BMT (P<0.05). The children at an age >or=6 years had obviously higher incidence of hemorrhagic cystitis than those at younger ages.

CONCLUSIONAge is the major factor that affects the occurrence of hemorrhagic cystitis in children undergoing allogeneic hematopoietic stem cell transplantation for beta-thalassemia.

OBJECTIVES: To explore the risk factors for hemorrhagic cystitis (HC) in children with β-thalassemia major (TM) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: A retrospective analysis was conducted on clinical data of 247 children with TM who underwent allo-HSCT at Shenzhen Children's Hospital from January 2021 to November 2022. The children were divided into an HC group (91 cases) and a non-HC group (156 cases) based on whether HC occurred after operation. Multivariable logistic regression analysis was used to explore the risk factors for HC, and the receiver operating characteristic curve was used to analyze the predictive efficacy of related factors for HC. RESULTS: Among the 247 TM patients who underwent allo-HSCT, the incidence of HC was 36.8% (91/247). Univariate analysis showed age, incompatible blood types between donors and recipients, occurrence of acute graft-versus-host disease (aGVHD), positive urine BK virus deoxyribonucleic acid (BKV-DNA), and ≥2 viral infections were associated with the development of HC after allo-HSCT (P<0.05). Multivariable analysis revealed that incompatible blood types between donors and recipients (OR=3.171, 95%CI: 1.538-6.539), occurrence of aGVHD (OR=2.581, 95%CI: 1.125-5.918), and positive urine BKV-DNA (OR=21.878, 95%CI: 9.633-49.687) were independent risk factors for HC in children with TM who underwent allo-HSCT. The receiver operating characteristic curve analysis showed that positive urine BKV-DNA alone or in combination with two other risk factors (occurrence of aGVHD, incompatible blood types between donors and recipients) had a certain accuracy in predicting the development of HC after allo-HSCT (area under the curve >0.8, P<0.05). CONCLUSIONS Incompatible blood types between donors and recipients, occurrence of aGVHD, and positive urine BKV-DNA are risk factors for HC after allo-HSCT in children with TM. Regular monitoring of urine BKV-DNA has a positive significance for early diagnosis and treatment of HC.

OBJECTIVES: To investigate the etiologies of urinary bladder involvement in patients with systemic lupus erythematosus (SLE), the clinicoradiologic features of gastrointestinal tract manifestations and clinical outcomes in patients with lupus cystitis accompanied by gastrointestinal manifestations. METHODS: We conducted a retrospective chart review on 413 patients with SLE. Patients were selected for review on the basis of lower urinary tract symptoms including urinary frequency, urgency and urinary incontinence. Radiologic studies were analyzed in patients with lupus cystitis. RESULTS: Ten consecutive patients, complicated with lower urinary tract symptoms, were identified. Underlying etiologies were as follows: lupus cystitis in five, neurogenic dysfunction secondary to transverse myelitis in three, cyclophosphamide-induced cystitis in one and tuberculous cystitis in one patient. All patients with lupus cystitis showed gastrointestinal manifestations, such as abdominal pain, nausea, vomiting and/or diarrhea during the periods of cystitis symptoms. In all patients with lupus cystitis, paralytic ileus was demonstrated on plain abdominal X-ray and ascites, bilateral hydroureteronephrosis and thickened bladder wall were identified on abdominal ultrasound or CT. Abdominal CT revealed bowel wall thickening in four of the five patients. The main sites of thickened bowel on abdominal CT were territory supplied by superior mesenteric artery. Two of five patients with lupus cystitis expired during the follow-up period. CONCLUSION: Diverse etiologies may cause lower urinary tract symptoms in patients with SLE. Lupus cystitis is strongly associated with gastrointestinal involvement and abdominal CT can be a useful radiologic tool to investigate the gastrointestinal tract involvement in patients with lupus cystitis.

We conducted a retrospective study to investigate the incidence, risk factors, and clinical features of hemorrhagic cystitis (HC) following allogeneic hematopoietic cell transplantation (allo-HCT). Adult patients who developed HC after allo-HCT were identified from the HCT database of the Asan Medical Center and their medical records were reviewed. From December 1993 to August 2001, a total of 210 adult patients underwent allo-HCT. Fifty-one patients developed HC with a cumulative incidence of 25.7%. The median onset of HC was post-transplant day 24 (range, -2 to 474), and the median duration was 31 days (range, 8 to 369). Significant risk factors for HC by univariate analysis included diagnosis of chronic myelogenous leukemia (p=0.028), unrelated HCT (p=0.029), grade III-IV acute graft-versus-host disease (GVHD) (p<0.001), extensive chronic GVHD (p=0.001), and positive cytomegalovirus antigenemia between post transplant days 31 and 60 (p=0.031). Multivariate analysis showed that grade III-IV acute GVHD was the most important risk factor for the occurrence of HC after allo-HCT (odds ratio, 3.38; 95% CI, 1.36-8.39). Late-onset HC, which occurred beyond 3 weeks after allo-HCT, was more frequently associated with GVHD than earlyonset HC (p=0.007). Our data suggest that a portion of late-onset HC might be a manifestation of GVHD.

Although asymptomatic bacteriuria, cystitis, and acute pyelonephritis (APN) have been categorized as urinary tract infections (UTIs), the immunopathogenesis of each disease is different. APN shows an age predilection; the majority of children (over 70-80%) with APN are under 1-2 years of age, with a male predominance. After 1-2 years of age, female predominance has been reported. This finding suggests that the immature immune state of infancy may be associated with the pathogenesis of APN. Escherichia coli is the most common etiologic agent; other uropathogens associated with UTIs originate from the host and comprise normal flora that are continuously altered by environmental factors. Therefore, uropathogens may have characteristics different from those of extraneous bacterial pathogens. Although antibiotic-resistant uropathogens, including extended-spectrum beta-lactamase-producing strains, are increasing in Korea and worldwide, treatment failure is rare in immune-competent children. The immunopathogenesis of APN remains unknown. Intact bacteria may not be the causative substances in renal cell injury; rather, smaller substances produced during bacterial replication may be responsible for renal cell injury and scarring. Moreover, substances from host cells such as proinflammatory cytokines may be involved in renal cell injury. A dimercaptosuccinic acid scan is used to detect the site of bacterial replication in the renal parenchyma, and may be influenced by the size of the focus and the stage of APN. Traditional aggressive studies used to identify vesicoureteral reflux after the first episode of APN have been modified because of rare cases of chronic kidney disease in patients with recurrent UTI.

Physicians need to be prepared with basic understandings of enuresis and practical tips to diagnose and treat the patients properly. The knowledge about the natural history, epidemiology, and etiology of enuresis, not to mention multiple treatment modalities available, are essential, Medical consultation and treatment of enuresis begins at the age of 5. Evaluation should include history taking, physical examination, and laboratory investigations. A checklist may be provided for quick evaluation in busy clinics. The two main treatment modalities are behavioral modification with an alarm system and pharmacotherapy with desmopressin or imipramine, or oxybutinin. The response to treatment is evaluated after a 1-to 3-months' period of treatment. further evaluation and individualized treatment are needed in poor responders. Normalization of a small functional bladder capacity may help to cure enuresis and treatment of enuresis with antibiotics is effective in children with urinary tract infection, bacteriuria, or cystitis cystica.

BACKGROUNDThe definite pathogenesis of hemorrhagic cystitis (HC) after allogenic hematopoietic stem cell transplantation (allo-HSCT) has not been well elucidated. The role of cytomegalovirus (CMV) reactivation and graft-versus-host disease (GVHD) in the development of HC remains obscure. This study determined the incidence and risk factors for HC after allo-HSCT and analyzed its association with CMV reactivation and GVHD.

METHODSWe retrospectively studied 250 patients at high risk for CMV disease who underwent allo-HSCT all based on busulfan/cyclophosphamide (BU/CY) myloablative regimens. The incidence, etiology, risk factors and clinical management of HC were investigated.

RESULTSHC developed within 180 days of transplant in 72 patients, with an overall incidence of 28.8% and an incidence of 12.6% in patients with HLA-matched related donors (MRD), 34.38% in those with HLA-matched unrelated donors (MUD), 49.45% in those with mismatched related donors (MMRD). CMV-viremia significantly increased the incidence of later onset HC (LOHC); however, only 9 out of 15 patients with CMV viruria actually developed LOHC. Multiple regression analysis identified grade II - IV acute GVHD (RR = 2.75; 95% CI 1.63 +/- 4.66; P < 0.01) and grafts from MUD or MMRD (RR = 2.60; 95% CI 1.52 +/- 5.20; P < 0.01) as independent risk factors for HC. Event sequence analysis indicated a majority of HC episodes began around GVHD initiation.

CONCLUSIONSCMV-viremia is a high risk factor for LOHC. Our data also showed a correlation between acute GVHD and HC, which suggested that alloimmunity may be involved in the pathogenesis of HC.

BACKGROUNDDespite 100 years of research, the continued absence of well-established risk factors impedes the diagnosis and treatment of interstitial cystitis/painful bladder syndrome (IC/PBS). We aimed to identify risk factors in patients with lower urinary tract symptoms (LUTS) without urinary tract infection or benign prostate hyperplasia in China.

METHODSA total of 397 outpatients with LUTS presenting for care to urology clinics in several hospitals throughout China were surveyed using a standardized questionnaire and validated outcome measures. The definitions for painful bladder syndrome based on the O'Leary-Sant interstitial cystitis symptom and problem indices were used. The prevalence of possible risk factors was analyzed using the Fisher's exact test and Pearson chi-square test, and multivariate predictive models were developed using binary Logistic regression methods.

RESULTSOf those multi-centre patients surveyed, including 174 women and 223 men, 41% (162/397) met criteria for painful bladder syndrome. There was a significant difference between women and men (55% (95/174) vs. 30% (67/223), P < 0.001). Women with IC/PBS were more likely than those without IC/PBS to report a history of gynecological infections (odds ratio (OR): 2.85; 95% confidence interval (CI): 1.32 - 6.16, P = 0.007), intake of stimulatory foods (OR: 3.52; 95%CI: 1.50 - 8.30; P = 0.004), irritable bowel (OR: 3.46; 95%CI: 1.22 - 9.80; P = 0.014) and/or anorectal disease (OR: 2.68; 95%CI: 1.12 - 6.40, P = 0.023). After adjusting for confounding factors, bladder pain was significantly associated with stimulatory foods (OR: 3.85; 95%CI: 1.58 - 9.36, P = 0.003) and anorectal disease (OR: 2.76; 95%CI: 1.09 - 7.04, P = 0.03) in women. Caffeine beverage intake (OR: 3.54; 95%CI: 1.54 - 8.12, P = 0.003) was identified the only modifiable association noted in multivariate analysis of men.

CONCLUSIONSWe found that stimulatory foods, anorectal disease and caffeine beverages are potential risk factors for IC/PBS. Further studies are necessary to determine their role in the pathogenesis of this disorder.
