Vaginal pessary: a culprit for intraperitoneal bladder perforation.

Vaginal pessaries are widely considered to be a safe and effective non-surgical management option for women with pelvic organ prolapse. Complications may occur, and are more frequent with improper care and certain device designs and materials. It is imperative to provide information to patients about potential complications. We present the case of a woman in her 70s who presented to the Emergency Department with increasing groin and abdominal pain following a vaginal pessary insertion 2 days prior for grade 3 vaginal vault prolapse. On presentation, her abdomen was markedly distended with guarding. Laboratory investigations showed a significant acute kidney injury with a metabolic acidosis. An initial non-contrast CT showed fluid and inflammatory changes surrounding the bladder, and bladder perforation was suspected. A subsequent CT cystogram showed extravasation of contrast from the bladder into the peritoneal cavity, in keeping with an intraperitoneal bladder rupture. The patient underwent an emergency bladder repair in theatre.

Diagnosis and management of complications following pelvic organ prolapse surgery using a synthetic mesh: French national guidelines for clinical practice.

Complications associated with pelvic organ prolapse (POP) surgery using a synthetic non-absorbable mesh are uncommon (<5%) but may be severe and may hugely diminish the quality of life of some women. In drawing up these multidisciplinary clinical practice recommendations, the French National Authority for Health (Haute Autorité de santé, HAS) conducted an exhaustive review of the literature concerning the diagnosis, prevention, and management of complications associated with POP surgery using a synthetic mesh. Each recommendation for practice was allocated a grade (A,B or C; or expert opinion (EO)), which depends on the level of evidence (clinical practice guidelines). PREOPERATIVE PATIENTS' INFORMATION: Each patient must be informed concerning the risks associated with POP surgery (EO). HEMORRHAGE, HEMATOMA: Vaginal infiltration using a vasoconstrictive solution is not recommended during POP surgery by the vaginal route (grade C). The placement of vaginal packing is not recommended following POP surgery by the vaginal route (grade C). During laparoscopic sacral colpopexy, when the promontory seems highly dangerous or when severe adhesions prevent access to the anterior vertebral ligament, alternative surgical techniques should be discussed per operatively, including colpopexy by lateral mesh laparoscopic suspension, uterosacral ligament suspension, open abdominal mesh surgery, or surgery by the vaginal route (EO). BLADDER INJURY: When a bladder injury is diagnosed, bladder repair by suturing is recommended, using a slow resorption suture thread, plus monitoring of the permeability of the ureters (before and after bladder repair) when the injury is located at the level of the trigone (EO). When a bladder injury is diagnosed, after bladder repair, a prosthetic mesh (polypropylene or polyester material) can be placed between the repaired bladder and the vagina, if the quality of the suturing is good. The recommended duration of bladder catheterization following bladder repair in this context of POP mesh surgery is from 5 to 10 days (EO). URETER INJURY: After ureteral repair, it is possible to continue sacral colpopexy and place the mesh if it is located away from the ureteral repair (EO). RECTAL INJURY: Regardless of the approach, when a rectal injury occurs, a posterior mesh should not be placed between the rectum and the vagina wall (EO). Concerning the anterior mesh, it is recommended to use a macroporous monofilament polypropylene mesh (EO). A polyester mesh is not recommended in this situation (EO). VAGINAL WALL INJURY: After vaginal wall repair, an anterior or a posterior microporous polypropylene mesh can be placed, if the quality of the repair is found to be satisfactory (EO). A polyester mesh should not be used after vaginal wall repair (EO). MESH INFECTION (ABSCESS, CELLULITIS, SPONDYLODISCITIS): Regardless of the surgical approach, intravenous antibiotic prophylaxis is recommended (aminopenicillin + beta-lactamase inhibitor: 30 min before skin incision +/- repeated after 2 h if surgery lasts longer) (EO). When spondylodiscitis is diagnosed following sacral colpopexy, treatment should be discussed by a multidisciplinary group, including especially spine specialists (rheumatologists, orthopedists, neurosurgeons) and infectious disease specialists (EO). When a pelvic abscess occurs following synthetic mesh sacral colpopexy, it is recommended to carry out complete mesh removal as soon as possible, combined with collection of intraoperative bacteriological samples, drainage of the collection and targeted antibiotic therapy (EO). Non-surgical conservative management with antibiotic therapy may be an option (EO) in certain conditions (absence of signs of sepsis, macroporous monofilament polypropylene type 1 mesh, prior microbiological documentation and multidisciplinary consultation for the choice of type and duration of antibiotic therapy), associated with close monitoring of the patient. BOWEL OCCLUSION RELATED TO NON-CLOSURE OF THE PERITONEUM: Peritoneal closure is recommended after placement of a synthetic mesh by the abdominal approach (EO). URINARY RETENTION: Preoperative urodynamics is recommended in women presenting with urinary symptoms (bladder outlet obstruction symptoms, overactive bladder syndrome or incontinence) (EO). It is recommended to remove the bladder catheter at the end of the procedure or within 48 h after POP surgery (grade B). Bladder emptying and post-void residual should be checked following POP surgery, before discharge (EO). When postoperative urine retention occurs after POP surgery, it is recommended to carry out indwelling catheterization and to prefer intermittent self-catheterization (EO). POSTOPERATIVE PAIN: Before POP surgery, the patient should be asked about risk factors for prolonged and chronic postoperative pain (pain sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Concerning the prevention of postoperative pain, it is recommended to carry out a pre-, per- and postoperative multimodal pain treatment (grade B). The use of ketamine intraoperatively is recommended for the prevention of chronic postoperative pelvic pain, especially for patients with risk factors (preoperative painful sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Postoperative prescription of opioids should be limited in quantity and duration (grade C). When acute neuropathic pain (sciatalgia or pudendal neuralgia) resistant to level I and II analgesics occurs following sacrospinous fixation, a reintervention is recommended for suspension suture removal (EO). When chronic postoperative pain occurs after POP surgery, it is recommended to systematically seek arguments in favor of neuropathic pain with the DN4 questionnaire (EO). When chronic postoperative pelvic pain occurs after POP surgery, central sensitization should be identified since it requires a consultation in a chronic pain department (EO). Concerning myofascial pain syndrome (clinical pain condition associated with increased muscle tension caused by myofascial trigger points), when chronic postoperative pain occurs after POP surgery, it is recommended to examine the levator ani, piriformis and obturator internus muscles, so as to identify trigger points on the pathway of the synthetic mesh (EO). Pelvic floor muscle training with muscle relaxation is recommended when myofascial pain syndrome is associated with chronic postoperative pain following POP surgery (EO). After failure of pelvic floor muscle training (3 months), it is recommended to discuss surgical removal of the synthetic mesh, during a multidisciplinary discussion group meeting (EO). Partial removal of synthetic mesh is indicated when a trigger point is located on the pathway of the mesh (EO). Total removal of synthetic mesh should be discussed during a multidisciplinary discussion group meeting when diffuse (no trigger point) chronic postoperative pain occurs following POP surgery, with or without central sensitization or neuropathic pain syndromes (EO). POSTOPERATIVE DYSPAREUNIA: When de novo postoperative dyspareunia occurs after POP surgery, surgical removal of the mesh should be discussed (EO). VAGINAL MESH EXPOSURE: To reduce the risk of vaginal mesh exposure, when hysterectomy is required during sacral colpopexy, subtotal hysterectomy is recommended (grade C). When asymptomatic vaginal macroporous monofilament polypropylene mesh exposure occurs, systematic imaging is not recommended. When vaginal polyester mesh exposure occurs, pelvic +/- lumbar MRI (EO) should be used to look for an abscess or spondylodiscitis, given the greater risk of infection associated with this type of material. When asymptomatic vaginal mesh exposure of less than 1 cm2 occurs in a woman with no sexual intercourse, the patient should be offered observation (no treatment) or local estrogen therapy (EO). However, if the patient wishes, partial excision of the mesh can be offered. When asymptomatic vaginal mesh exposure of more than 1 cm2 occurs or if the woman has sexual intercourse, or if it is a polyester prosthesis, partial mesh excision, either immediately or after local estrogen therapy, should be offered (EO). When symptomatic vaginal mesh exposure occurs, but without infectious complications, surgical removal of the exposed part of the mesh by the vaginal route is recommended (EO), and not systematic complete excision of the mesh. Following sacral colpopexy, complete removal of the mesh (by laparoscopy or laparotomy) is only required in the presence of an abscess or spondylodiscitis (EO). When vaginal mesh exposure recurs after a first reoperation, the patient should be treated by an experienced team specialized in this type of complication (EO). SUTURE THREAD VAGINAL EXPOSURE: For women presenting with vaginal exposure to non-absorbable suture thread following POP surgery with mesh reinforcement, the suture thread should be removed by the vaginal route (EO). Removal of the surrounding mesh is only recommended when vaginal mesh exposure or associated abscess is diagnosed. BLADDER AND URETERAL MESH EXPOSURE: When bladder mesh exposure occurs, removal of the exposed part of the mesh is recommended (grade B). Both alternatives (total or partial mesh removal) should be discussed with the patient and should be debated during a multidisciplinary discussion group meeting (EO).

Systematic review of urological injury during caesarean section and hysterectomy.

INTRODUCTION AND HYPOTHESIS: We aim to review iatrogenic bladder and ureteric injuries sustained during caesarean section and hysterectomy. METHODS: A search of Cochrane, Embase, Medline and grey literature was performed using methods pre-published on PROSPERO. Eligible studies described iatrogenic bladder or ureter injury rates during caesarean section or hysterectomy. The 15 largest studies were included for each procedure sub-type and meta-analyses performed. The primary outcome was injury incidence. Secondary outcomes were risk factors and preventative measures. RESULTS: Ninety-six eligible studies were identified, representing 1,741,894 women. Amongst women undergoing caesarean section, weighted pooled rates of bladder or ureteric injury per 100,000 procedures were 267 or 9 events respectively. Injury rates during hysterectomy varied by approach and pathological condition. Weighted pooled mean rates for bladder injury were 212-997 events per 100,000 procedures for all approaches (open, vaginal, laparoscopic, laparoscopically assisted vaginal and robot assisted) and all pathological conditions (benign, malignant, any), except for open peripartum hysterectomy (6,279 events) and laparoscopic hysterectomy for malignancy (1,553 events). Similarly, weighted pooled mean rates for ureteric injury were 9-577 events per 100,000 procedures for all hysterectomy approaches and pathologies, except for open peripartum hysterectomy (666 events) and laparoscopic hysterectomy for malignancy (814 events). Surgeon inexperience was the prime risk factor for injury, and improved anatomical knowledge the leading preventative strategy. CONCLUSIONS: Caesarean section and most types of hysterectomy carry low rates of urological injury. Obstetricians and gynaecologists should counsel the patient for her individual risk of injury, prospectively establish risk factors and implement preventative strategies.

Retrospective analysis of bladder perforation risk in patients after augmentation cystoplasty using an extraperitoneal approach.

BACKGROUND: Initial management of pediatric patients with neurogenic bladder is focused on clean intermittent catheterization and medical therapies. Those with more hostile or small capacity bladders require surgical intervention including bladder augmentation that can result in significant clinical sequelae. This study examines a rarely described approach wherein the bladder reconstruction is extraperitonealized by bringing bowel segments through a peritoneal window and then closed. OBJECTIVE: The aim of this study was to determine if the rate of bladder rupture and subsequent morbidity differed between patients who have undergone an intraperitoneal versus extraperitoneal bladder augmentation. We hypothesized that an extraperitoneal approach reduced the risk of intraperitoneal bladder perforation, downstream Intensive Care Unit (ICU) admission, small bowel obstruction (SBO) requiring exploratory laparotomy, and ventriculoperitoneal (VP) shunt-related difficulties as compared to the standard intraperitoneal technique. METHODS: A retrospective chart review was conducted to assess surgical approach and outcomes in patients who underwent bladder augmentation performed between January 2009 and June 2021. Patients were identified through an existing database and manual chart review was conducted to extract data through imaging studies, operative notes, and clinical documentation. The primary outcome was bladder perforation. Secondary outcomes were ICU admission, exploratory laparotomy, and VP shunt externalization, infection, or revision for any cause. Nonparametric statistical analyses were performed. RESULTS: A total of 111 patients underwent bladder augmentation with 37 intraperitoneal and 74 extraperitoneal procedures. Median follow up was 5.8 years [IQR 3.0-8.6 years] and did not vary between groups (P = 0.67). Only one patient was found to have a bladder perforation in the intraperitoneal group (log-rank P = 0.154). There were no significant differences in time to post-augmentation ICU admission, exploratory laparotomy, or VP shunt events between the two groups (log-rank P = 0.294, log-rank P = 0.832, and log-rank P = 0.237, respectively). Furthermore, a Kaplan-Meier analysis assessing time to composite complication demonstrated no significant difference between the two techniques (log-rank P = 0.236). DISCUSSION: This study provides important data comparing the rate of bladder perforation and subsequent morbidity between intraperitoneal and extraperitoneal bladder augmentation. As expected, with a complex procedure, both groups suffered complications, but these data showed no difference between the two procedures. Rates of prior (abdominal) surgery may influence the decision to perform this procedure extraperitoneal. CONCLUSIONS: Outcomes related to bladder perforation and secondary consequences do not differ significantly between patients who had bladder augmentation performed with an intraperitoneal versus extraperitoneal approach. Given the low number of adverse events in this study, larger studies are warranted.

[A CASE OF PERIVESICAL ABSCESS CAUSED BY MIGRATION OF A FOREIGN BODY FROM THE INTESTINAL TRACT].

A 76-year-old woman was referred to our department because of high fever and bladder irritative symptoms. Computed tomography revealed the presence of a heterogeneous mass with indistinct borders on the left anterior wall of the bladder. The lesion contained a linear hyperdense shadow. We initially suspected malignancy, such as urachal carcinoma or soft-tissue sarcoma. However, upon review of previous computed tomography scans, it was confirmed that the linear hyperdense shadow had migrated from the intestinal tract to the bladder. Considering the possibility of abscess formation caused by a foreign body, we decided to perform a transurethral biopsy. The results of the pathological analysis showed abscess formation. The patient was diagnosed with perivesical abscess caused by accidental ingestion of a fish bone. Following the administration of antibiotics, the lesion markedly shrank. Although it is difficult to distinguish perivesical abscess from malignant disease, invasive treatment can be avoided by appropriate diagnosis based on imaging studies.

[Usefulness of Ascitic Fluid Analysis for Diagnosis of Intraperitoneal Bladder Rupture : A Case Report].

An inebriated 58-year-old woman with a history of hysterectomy presented to the emergency department with abdominal pain. The patient received hydration and acetaminophen, which led to symptom resolution. The patient returned with severe abdominal pain, 12 hours later. Computed tomography (CT) revealed a large volume of ascites and bladder wall disruption. Ascitic fluid analysis showed an elevated creatinine (Cre) level of 7.56 mg/dl, and the ascites to serum Cre ratio was 2.96, which indicated urinary ascites secondary to bladder rupture. The patient was diagnosed with intraperitoneal bladder rupture and underwent successful conservative treatment using an indwelling urinary catheter.

Early Detrusor Application of Botulinum Toxin A Results in Reduced Bladder Hypertrophy and Fibrosis after Spinal Cord Injury in a Rodent Model.

Following spinal cord injury (SCI), pathological reflexes develop that result in altered bladder function and sphincter dis-coordination, with accompanying changes in the detrusor. Bladder chemodenervation is known to ablate the pathological reflexes, but the resultant effects on the bladder tissue are poorly defined. In a rodent model of contusion SCI, we examined the effect of early bladder chemodenervation with botulinum toxin A (BoNT-A) on bladder histopathology and collagen deposition. Adult female Long Evans rats were given a severe contusion SCI at spinal level T9. The SCI rats immediately underwent open laparotomy and received detrusor injections of either BoNT-A (10 U/animal) or saline. At eight weeks post injury, the bladders were collected, weighed, and examined histologically. BoNT-A injected bladders of SCI rats (SCI + BoNT-A) weighed significantly less than saline injected bladders of SCI rats (SCI + saline) (241 ± 25 mg vs. 183 ± 42 mg; p < 0.05). Histological analyses showed that SCI resulted in significantly thicker bladder walls due to detrusor hypertrophy and fibrosis compared to bladders from uninjured animals (339 ± 89.0 µm vs. 193 ± 47.9 µm; p < 0.0001). SCI + BoNT-A animals had significantly thinner bladder walls compared to SCI + saline animals (202 ± 55.4 µm vs. 339 ± 89.0 µm; p < 0.0001). SCI + BoNT-A animals had collagen organization in the bladder walls similar to that of uninjured animals. Detrusor chemodenervation soon after SCI appears to preserve bladder tissue integrity by reducing the development of detrusor fibrosis and hypertrophy associated with SCI.

Diffused bladder wall calcification in a survivor with severe coronavirus disease 2019: A case report.

RATIONALE: Bladder calcification is a rare presentation that was first interpreted to be related to a urea-splitting bacterial infection. Aside from infection, other hypotheses such as schistosomiasis, tuberculosis, cancer, and cytokine-induced inflammatory processes have also been reported. Severe coronavirus disease 2019 (COVID-19) is known for its provoking cytokine storm and uninhibited systematic inflammation, and calcification over the coronary artery or lung has been reported as a long-term complication. PATIENT CONCERNS: We presented a 68 years old man who had persistent lower urinary tract symptoms after recovery from severe COVID-19. No urea-splitting bacteria were identified from urine culture. DIAGNOSIS: Cystoscopy examination revealed diffuse bladder mucosal and submucosa calcification. INTERVENTIONS: Transurethral removal of the mucosal calcification with lithotripsy. OUTCOMES: The patient's lower urinary tract symptoms improved, and stone analysis showed 98% calcium phosphate and 2% calcium oxalate. No newly formed calcifications were found at serial follow-up. CONCLUSION: Diffuse bladder calcification may be a urinary tract sequela of COVID-19 infection. Patients with de novo lower urinary tract symptoms after severe COVID-19 should be further investigated.

Sexuality and quality of life after nerve-sparing radical hysterectomy for cervical cancer: A prospective study.

OBJECTIVE: Nerve-sparing radical hysterectomy (NSRH) decreases the negative postoperative consequences of radical surgery for cervical cancer, such as bladder evacuation disorders, colorectal motility disorders, and sexual dysfunction. The aim of this study was to prospectively assess the sexuality and quality of life in a group of women who underwent NSRH with lymphadenectomy for cervical cancer. MATERIALS AND METHODS: A total of 65 patients with early-stage cervical cancer underwent NSRH between 2014 and 2016. Patient examinations and questionnaire surveys (Female Sexual Function Index questionnaire and European Organization for Research and Treatment of Cancer questionnaires QLQ-C30 and QLQ-CX24) were conducted, before and one year after the surgery. RESULTS: After the exclusion of 19 sexually inactive women and 10 women who received adjuvant anticancer treatment, 36 sexually active patients treated solely with nerve-sparing surgery were eligible for evaluation. The mean age was 47 years. The average preoperative vaginal length was 9.4 cm, whereas the postoperative length was shortened to 7.1 cm. This study showed no negative impact of NSRH on sexual desire, arousal, satisfaction, orgasm, pain, sexual activity, sexual enjoyment, and sexual worry. The worsening of sexual functioning was recorded during the one-year follow-up. The QLQ-C30 questionnaire confirmed postoperative improvement in global health status and role, emotional, and social functioning. CONCLUSION: Our study showed using standardized questionnaires that NSRH has no negative impact on sexual desire, arousal, satisfaction, orgasm, pain, sexual activity, frequency of sexual intercourse, sexual enjoyment, and sexual worry, while only the worsening of sexual functioning was recorded. Moreover, NSRH did not cause postoperative deterioration in the quality of life parameters.

Pseudorenal failure as a delayed presentation of a traumatic urinary bladder rupture.

The urinary bladder is less susceptible to traumatic injury than other abdominal organs, due to its anatomical location behind the pubic bone. As a result, intraperitoneal urinary bladder ruptures are a rare consequence of blunt abdominal trauma and most often occur in the context of high energy and multitraumas. However, a distended bladder is more vulnerable to burst rupture even from a minor trauma, and in case of an isolated bladder injury, presentation can be delayed. We describe a case in which a patient presented 4 days after a minor blunt trauma, with an acute abdomen and pseudorenal failure as the main clinical signs of urinary ascites due to a significant bladder rupture. As an intraperitoneal bladder rupture is associated with significant morbidity and mortality and should be treated surgically, it should always be considered in patients presenting with anuria, ascites and increased serum creatinine after abdominal trauma.

Inhibition of CXCR4 in Spinal Cord and DRG with AMD3100 Attenuates Colon-Bladder Cross-Organ Sensitization.

BACKGROUND: Cross-sensitization of pelvic organs is one theory for why symptoms of gut sickness and interstitial cystitis/bladder pain syndrome overlap. Experimental colitis has been shown to trigger bladder hyperactivity and hyperalgesia in rats. The chemokine receptor CXCR4 plays a key role in bladder function and central sensitization. We aim to study the role of CXCR4 and its inhibitor AMD3100 in colon-bladder cross-organ sensitization. METHODS: The colitis model was established by rectal infusion of trinitrobenzene sulfonic acid. Western blot and immunofluorescence were used to assess the expression and distribution of CXCR4. Intrathecal injection of AMD3100 (a CXCR4 inhibitor) and PD98059 (an ERK inhibitor) were used to inhibit CXCR4 and downstream extracellular signal-regulated kinase (ERK) in the spinal cord and dorsal root ganglion (DRG). Intravesical perfusion of resiniferatoxin was performed to measure the pain behavior counts of rats, and continuous cystometry was performed to evaluate bladder voiding function. RESULTS: Compared to the control group, CXCR4 was expressed more in bladder mucosa and colon mucosa, L6-S1 dorsal root ganglion (DRG), and the corresponding segment of the spinal dorsal horn (SDH) in rats with colitis. Moreover, intrathecal injection of the AMD3100 suppressed bladder overactivity, bladder hyperalgesia, and mastocytosis symptoms caused by colitis. Furthermore, AMD3100 effectively inhibited ERK activation in the spinal cord induced by experimental colitis. Finally, treatment with PD98059 alleviated bladder overactivity and hyperalgesia caused by colitis. CONCLUSION: Increased CXCR4 in the DRG and SDH contributes to colon inflammation-induced bladder overactivity and hyperalgesia partly via the phosphorylation of spinal ERK. Treatment targeting the CXCR4/ERK pathway might provide a potential new approach for the comorbidity between the digestive system and the urinary system.

Treatment of complicated bladder rupture with novel percutaneous interventional treatment technique.

Bladder rupture (BR) is very rare and usually occurs after high-energy events. Although high success rates have been reported for surgical intervention, it has not been clearly stated in the literature what could be done in cases where surgery has been unsuccessful. In this case report, we aimed to demonstrate that we provided treatment with the novel interventional technique in our young patient whose urinary leakage and sepsis persisted despite repeated surgeries and prolonged nephrostomy catheter drainage.

The deceiving encounter of a spontaneously ruptured urinary bladder.

Spontaneous urinary bladder rupture is a rare condition. Radiotherapy treatment for malignancy of a pelvic organ such as cervix or prostate is one cause of this condition. We report a case of a 71-year-old woman who presented with this illness 30 years after radiotherapy treatment.

Outcome of Urinary Bladder Dysfunction in Children.

Bladder dysfunction in children is common, the most frequent underlying causes are neurologic bladder (NB), dysfunctional voiding syndrome (DVS), and the valve bladder syndrome (VBS). The aim of this study was to determine the 10-y survival rate and the associated morbidities in children with bladder dysfunction. One hundred ninety-nine children were included in the study; 60 with VBS, 75 DVS, and 64 NB. The mean age was 44 mo (CI: 37-50.9) and mean GFR 50.1 (CI 44.6-55.6) mL/min/1.73m2. The 10-y survival rate was 89%. Compared with patients with VBS, the mortality was 11 times higher among patients with NB (p = 0.02) but not significantly higher than patients with DVS (p = 0.2). GFR < 15 mL/min/1.73 m2 increases mortality rate by 6 times compared with normal GFR (p = 0.007). Late age at presentation (> 5 y) increases mortality risk and/or the need for renal replacement therapy (RRT) by almost 5 times (p = 0.013). It was concluded that the etiology of bladder dysfunction, baseline GFR, and the age at presentation significantly influence the survival rate and morbidities.

The Effect of Early Infection on the Rate of Volitional Voiding after Spinal Cord Injury: A Potential Modifiable Risk Factor for Bladder Outcomes.

PURPOSE: Recently, it has been observed that early infections after spinal cord injury (SCI) are associated with decreased long-term motor and sensory recovery. We investigate the effects of early infection after SCI on long-term bladder function. MATERIALS AND METHODS: We assessed data for the years 1995 to 2006 using the National Spinal Cord Injury Database. Postoperative wound infections and pneumonia were used to classify infections during the acute inpatient and rehabilitation periods. The effect of early infections on volitional voiding status at 1-year followup was assessed. Age, gender and neurological status at rehabilitation discharge (level of injury, American Spinal Injury Association Impairment Scale [AIS] and bilateral lower extremity motor scores) were included in multivariate logistic regression modeling to control for confounding. RESULTS: Of the 3,561 persons studied, 1,233 (34.6%) had an early infection. Those with an infection during early recovery were less likely to void than their noninfected counterparts if in the AIS A (0.3% vs 1.9%, p=0.010), AIS B (3.8% vs 10.5%, p=0.018) and AIS C (29.1% vs 37.3%, p=0.071) classification, while those with less complete injuries (AIS D) did not appear to be affected (62.6% vs 65.4%, p=0.456). Similar findings were found when stratifying by lower extremity motor scores and persisted on multivariate analysis, where early infection decreased the odds of volitional voiding at 1-year followup (OR=0.79, p=0.042). CONCLUSIONS: Infections during the early recovery period may modify volitional voiding at 1-year followup by 20% or more. Future investigations to confirm our findings and potentially evaluate mitigation strategies are warranted.

Bladder Necrosis at Time of Presentation with Ulcerative Colitis in an 8-year-old Female: A Case Report.

A case of bladder necrosis in an 8-year-old female at time of presentation of ulcerative colitis (UC) is presented. A case of bladder necrosis in a pediatric patient outside of the neonatal period has not been reported. The patient presented with abdominal pain, bloody stools, hematuria, and acute renal failure. She was acutely management with bilateral nephrostomy tube placement. Bladder and colon biopsies revealed diagnosis of UC and bladder necrosis. The UC was medically managed. The bladder did not regenerate after several months of observation and ileal conduit urinary diversion was performed. A right proximal ureteral stricture was managed by pyeloplasty at time of ileal conduit. The patient is doing well over 1 year after surgery.

Successful conservative management of a spontaneous intraperitoneal urinary bladder rupture secondary to benign prostatic hyperplasia: a case report.

A spontaneous intraperitoneal bladder rupture is a rare, serious and life-threatening surgical emergency of various etiologies, with unspecific clinical presentation, and difficult diagnosis. Surgical treatment is the standard therapy for intraperitoneal bladder rupture; however, there is an increasing tendency toward conservative management in selected patients with favorable characteristics. Herein, we report a rare case of a 65-year-old male patient presented to the emergency department with intraperitoneal bladder rupture following an episode of acute urinary retention due to benign prostatic hyperplasia, and which was successfully managed conservatively with urinary bladder catheterization and antibiotic therapy, without any complication.

Association between case signalment and disease diagnosis in urinary bladder disease in Australian cats and dogs.

Urinary bladder diseases are common in dogs and cats; however, there is little published work on urinary bladder disease in Australian pets. We identified pathology records of Australian dogs and cats with urinary bladder tissue submitted to the University of Queensland Veterinary Laboratory Service during 1994-2016 (n = 320). We described the proportion of bladder diseases in dogs and cats, and applied the less-commonly used logistic regression procedure to quantify associations between signalment variables and disease diagnosis that were evident using descriptive statistics alone. After preliminary analysis, both species were combined because of similar results. Spayed/castrated animals were 74% less likely to be diagnosed with cystitis compared with intact animals. Animals 4-11 y old were also at lower risk of being diagnosed with cystitis compared with younger or older animals. Male animals were at increased risk of neoplasia compared to females, which contrasts with reports from North America and Europe. There was increased risk for developing neoplasia with progressive age, with up to 20 times higher odds in the > 11-y age group. Logistic regression modeling provided unique insight into proportionate morbidity of urinary bladder diseases in Australian dogs and cats.
