Uma abordagem qualitativa sobre o uso do cateter urinário de longo prazo no contexto ambulatorial / A qualitative approach on long-term indwelling catheter use in an outpatient setting

Resumo O cateter vesical de longa permanência pode ser indicado em situações clínicas, como nas doenças crônicas do sistema genitourinário ou neurológico. Além dos riscos de infecção, traumas e sangramentos, a permanência do cateter pode afetar dimensões psicoemocionais e socioeconômicas. Objetivamos compreender como a necessidade de uso do cateter urinário por um longo prazo afeta a autopercepção, as interrelações e o autocuidado deste paciente. Realizamos um estudo qualitativo, descritivo, a partir da entrevista de 17 pacientes, e aplicamos a análise temática e o pensamento complexo. Os diferentes prognósticos e as expectativas em relação ao cateter influenciaram a autopercepção, a adaptação, sua aceitação ou negação. A presença do cateter, seja como medida curativa ou para conforto, pode afetar a autoimagem e a sexualidade, gerar inseguranças e incertezas, que requerem compreensão da multidimensionalidade das situações, que sofrem interferências do meio pessoal, familiar e social, bem como da capacidade dos sistemas de saúde para o seu enfrentamento. Apesar dos desafios, a maioria dos participantes relatou disposição favorável para o autocuidado, seja para viabilizar retirada do cateter, ou para prevenir agravos em indicações vitalícias.

Abstract A long-term indwelling catheter may be indicated in clinical situations, such as chronic diseases of the genitourinary or neurological systems. In addition to the risks of infection, trauma, and bleeding, a catheter's permanence can affect psycho-emotional and socioeconomic dimensions. We aimed to understand how the need to use a long-term indwelling catheter affects this patient's self-perception, interrelationships, and self-care. We carried out a qualitative, descriptive study based on interviews with 17 patients, and applied thematic analysis and complex thinking. The different prognoses and expectations regarding the catheter influenced self-perception, adaptation, acceptance, or denial. The presence of a catheter, whether as a curative measure or for comfort, can affect self-image and sexuality, and generate insecurities and uncertainties, which require understanding the multidimensionality of situations that suffer interference from the personal, family, and social environment, as well as health systems' capacity to deal with it. Despite the challenges, the majority of participants reported a favorable disposition towards self-care, whether to enable catheter removal or to prevent injuries in lifelong indications.

Surgical excision of acquired urethral diverticulum and single-stage urethroplasty for a 32-year-old male. Case report and literature review.

INTRODUCTION: Urethral diverticulum (UD) is a saccular dilatation of the urethral wall, continuous with the true urethral lumen. It is categorized etiologically into congenital and acquired. The etiology of an acquired urethral diverticulum is thought to be secondary to trauma. The gold standard imaging modalities for diagnosis of UD are retrograde urethrogram (RGU) and micturating cystourethrogram (MCU). Management options include: nonoperative treatment, minimally invasive and open surgeries. Open surgeries comprise a primary anastomosis or, Substitution urethroplasty after UD excision, with the aim of excising the diverticulum, reestablishing the continuity of the urethra, and prevent urethrocutaneous fistula formation. We present a case of urethral diverticulum and bulbar urethral stricture successfully managed by surgical excision of UD and substitution urethroplasty. CASE PRESENTATION: We report a case of a 32-year-old man who had lower urinary tract symptoms following a traumatic urethral catheterization. Investigations done in a peripheral hospital revealed a short, bulbar urethral stricture and direct visual internal urethrotomy (DVIU) was done. Later he presented to us with urine retention, whereupon emergency suprapubic cystostomy was performed. After serial investigations, urethral diverticulectomy followed by single stage urethroplasty with ventral onlay buccal mucosa graft was done. He was followed for 12 months with good surgical outcome. DISCUSSION: The development of Acquired UD has been attributed to several possible factors: pelvic fractures, urethral strictures, straddle injuries, long-term urethral catheterization, endoscopic direct injuries, lower urinary tract infections, and urethral surgeries. Depending on the presentation and investigation findings, management of UD is planned. Conservative management is possible for uncomplicated asymptomatic UD if the patient consents to follow-up. Surgery to remove the diverticulum and urethral reconstruction are required for complicated symptomatic UD; these procedures vary from patient to patient and are individualized. CONCLUSION: It is important to base the choice to do surgery on the clinical presentation. Whether a concurrent urethral stricture is present is a critical factor in deciding on the best course of surgical treatment. In our case we opted to perform a substitution urethroplasty with ventral onlay buccal mucosa graft as our patient had a long bulbar urethral stricture proximal to the diverticulum.

A novel trauma induced urethral stricture in rat model.

Urethral stricture (US) is a longstanding disease, while there has not existed a suitable animal model to mimic the condition. We aimed to establish a trauma-induced US animal model to simulate this clinical scenario. A total of 30 rats were equally distributed into two groups, sham and US group. All rats were anesthetized with isoflurane and undergone cystostomy. In the US group, a 2 mm incision was made in the urethra and sutured to induce US. The sham group only make a skin incision on the ventral side of the anterior urethra. 4 weeks later, ultrasound and cystourethrography were performed to evaluate the degree of urethral stricture, pathological examinations were carried out to evaluate the degree of fibrosis. Urodynamic evaluation and mechanical tissue testing were performed to evaluate the bladder function and urethral tissue stiffness. The results showed that the urethral mucosa was disrupted and urethral lumen was stenosed in the US group. Additionally, the US group showed elevated bladder pressure, prolonged micturition intervals and increased tissue stiffness. In conclusion, the rat urethral stricture model induced by trauma provides a closer representation of the real clinical scenario. This model will significantly contribute to advancing research on the mechanisms underlying traumatic urethral stricture.

Modified tube cystostomy technique for management of obstructive urolithiasis in small ruminants: procedure and outcome in 17 sheep and goats.

OBJECTIVE: To describe the surgical technique and clinical outcome of small ruminants treated for obstructive urolithiasis using a modified tube cystostomy (MTC) technique. ANIMALS: 15 goats and 2 sheep treated with an MTC between March 2018 and February 2023. CLINICAL PRESENTATION: Animals were diagnosed with obstructive urolithiasis on the basis of history, physical examination, and ultrasonographic examination. An MTC was performed with sedation and a local block. Postoperative medical management was instituted to help reestablish urethral patency, and Foley catheters were removed after successful urination. RESULTS: Animals were hospitalized an average of 3 nights (range, 0 to 14 nights). Complications included urine spillage in the abdomen and accidental deflation of the Foley balloon. Six animals were euthanized due to poor prognosis or failure to regain urethral patency. Foley catheters were removed an average of 15.7 days postoperatively in animals that regained urethral patency. Long-term (> 1-month) follow-up was available for 8 animals, with an average postoperative survival time of 19.4 months (range, 1 to 58 months). Four animals were lost to long-term follow-up. CLINICAL RELEVANCE: This MTC technique is an effective means of catheterizing the urinary bladder in small ruminants. It can be performed under field conditions and serve as a standalone procedure for providing temporary urine egress. Patient size is limited by the length of the introducer, and an intact, distended urinary bladder and plan for reestablishing urethral patency are important considerations.

Delay in diagnosis of urethral perforation due to catheterisation in a person with cervical spinal cord injury. Importance of (1) imaging studies done promptly for detection and documentation of urethral trauma, (2) Urethrotech catheterisation device to minimise urethral trauma and achieve successful catheterisation: A case report.

INTRODUCTION AND IMPORTANCE: Spinal cord injury patients are at risk for urethral trauma during catheterisation. We report a patient in whom urethral perforation due to catheterisation was not recognised for ∼ four days. CASE PRESENTATION: Following a routine catheter change by community nurses in a male person with tetraplegia, the catheter drained only a small amount of urine. Therefore, the patient attended the hospital where the staff removed the catheter but could not place a new catheter. The doctor tried different catheters and on fifth attempt, inserted a catheter. The patient continued to bypass urine and was prescribed Solifenacin. On self-referral to spinal unit, urethral trauma was suspected. CT of pelvis revealed the balloon of the Foley catheter in the penile urethra at penis base with the tip projecting beyond the penile shaft. Suprapubic cystostomy was done. The patient continued to leak urine from the penis; required penile sheath drainage and an additional leg bag. CLINICAL DISCUSSION: This case illustrates the value of CT of pelvis including the penis in detecting urethral trauma and misplacement of the catheter. Physicians should look for symptoms and signs of urethral trauma and incorrect positioning of the catheter. Imaging studies should be done without delay to assess urethral trauma and misplacement of urinary catheter. CONCLUSION: We use Urethrotech urethral catheterisation in patients in whom the first attempt to insert a catheter per urethra is unsuccessful, or in patients with a history of difficult catheterisation. This helped to minimise urethral trauma and achieve successful catheterisation.

Postoperative urinary leakage after bilateral totally extraperitoneal herniorrhaphy in a patient with a healed cystostomy and appendectomy: A case report.

We report a case of postoperative urinary leakage after bilateral laparoscopic totally extraperitoneal (TEP) herniorrhaphy. A man in his upper 80s with a healed cystostomy and appendectomy underwent bilateral TEP herniorrhaphy. Urinary leakage was noted by ultrasound examination 4 days after bilateral TEP. Cystography and computed tomography conclusively confirmed a 6-mm extraperitoneal fistula at the site of the previous cystostomy. The fistula involved the anterior bladder wall and was associated with an extended urinoma. The patient was treated by indwelling catheterization using a Foley catheter and repeated ultrasound-guided puncture and aspiration of the inguinal effusion at the bedside. The patient was completely healed 69 days after the operation with no mesh infection or bladder dysfunction. We believe that urinary leakage is possible after TEP herniorrhaphy in patients with a healed suprapubic cystostomy. Therefore, indwelling catheterization using a Foley catheter should be implemented before surgery, and the Foley catheter can be removed within 1 week after surgery if no postoperative urinary leakage is observed. A history of suprapubic cystotomy should not be regarded as a contraindication for TEP surgery. This is the first report of urinary leakage after bilateral TEP herniorrhaphy in a patient with a healed cystostomy and appendectomy.

Giant bladder calculi due to four years neglected cystostomy.

Giant bladder calculi are rare and long-term usage of cystostomy could cause stone formation. Due to the lack of evidence on giant bladder calculi and the long-term usage of cystostomy can cause bladder calculi formation, we provide a case study of a man with a neglected cystostomy with giant bladder calculi for 4 years. A fixed mass was discovered in the suprapubic region. Ultrasound examination revealed 4.1 × 5.5 cm bladder calculi and contracted left kidney. Bipolar voiding cystourethrography portrayed stricture in pars pendular and membranacea, uneven bladder wall, and 4.5 × 4.5 cm bladder calculi. The stone was extracted, and the bladder filling test revealed a small bladder capacity. Since the patient refused urethral reconstruction and bladder augmentation, he was discharged with another cystostomy catheter. Six-month follow-up revealed no forming stones. Neglected cystostomy catheter can cause giant bladder calculi. Prompt diagnosis and treatment should be made to manage this condition to reduce the likelihood of bladder cancer.

Case report: Utility, complications, and short-term outcomes in three dogs managed with percutaneous pigtail cystostomy catheters for urethral obstruction.

Objective: This study aimed to describe the utility, complications, and short-term outcomes of three dogs managed with percutaneous pigtail cystostomy catheters placed in the emergency room (ER). Case summary: Three dogs were presented separately to the ER for unalleviated mechanical urethral obstruction secondary to urolithiasis and urethral neoplasia. Retrograde urinary catheterization and urohydropulsion were not successful after multiple attempts. Percutaneous pigtail cystostomy catheters were placed under sedation to achieve temporary urinary diversion, and were successful in two of the three dogs. Complications encountered include mild abdominal effusion, unsuccessful placement resulting in hemorrhagic abdominal effusion, steatitis, abdominal pain, and kinking of the catheter. The two dogs diagnosed with urolithiasis were discharged from the hospital, and the dog diagnosed with urethral neoplasia was humanely euthanized due to poor prognosis. New or unique information provided: When successful, the placement of pigtail cystostomy catheters allowed for temporary urinary diversion until definitive treatment could be performed and were well tolerated. Short-term outcomes were good. Complications arising from this procedure were common and increased morbidity. The risk of unsuccessful catheter placement may be increased when the procedure is performed in an over conditioned patient or by an inexperienced operator. Careful case selection and risk-benefit analysis should be considered before attempting this procedure. Further studies are necessary to evaluate the ideal technique, incidence of complications, and outcomes of this procedure.

Tube cystostomy is effective for urinary outflow management in dogs with intervertebral disk extrusion and ischemic myelopathy cranial to the L3 spinal cord segment: 61 dogs (2018-2022).

OBJECTIVE: To describe the application and owner experience of tube cystostomy for management of upper motor neuron urinary bladder dysfunction secondary to intervertebral disk extrusion (IVDE) or ischemic myelopathy, and to report complications associated with cystostomy tube management. ANIMALS: 61 dogs. CLINICAL PRESENTATION: Medical records of dogs with IVDE or ischemic myelopathy cranial to the L3 spinal cord segment that underwent tube cystostomy placement via a short, caudal ventral midline celiotomy were reviewed. Days from tube placement to hospital discharge, days from placement to tube removal, and complications were recorded. An owner questionnaire was distributed to ascertain ease of use and perceived time commitment. RESULTS: 58 dogs were diagnosed with IVDE, and 3 dogs were diagnosed with ischemic myelopathy. The modal neurologic grade at cystostomy tube placement was 4 (range, 3 to 5). The median number of days from cystostomy tube placement to hospital discharge was 1 (range, 0 to 3). Follow-up data was available for 56 dogs. The median number of days from cystostomy tube placement until removal was 19 (range, 3 to 74). Fifteen minor and 6 severe postoperative complications were reported, mainly inadvertent removal (n = 11) and peristomal urine leakage (6). Twenty-seven owners responded to the questionnaire and primarily reported that cystostomy tube use was easy (22/27) and perceived time commitment was low or minimal (20/27). CLINICAL RELEVANCE: Tube cystostomy facilitates early hospital discharge and allows at-home, extended urinary management in dogs recovering from upper motor neuron urinary bladder dysfunction secondary to IVDE or ischemic myelopathy. This technique is simple for owners to use.

Improving Foley Catheter Insertion Procedure by Developing Foley Introducer: A 100-Year Overdue Innovation.

PURPOSE: Foley catheter (FC) insertion is very basic yet one of the most widely performed procedures all across the fields of medicine. Since FC was first introduced in 19020's, no significant improvement has been made in view of methodology, despite the inconvenience associated with cumbersome preparation, procedure, and the patients' discomfort with having to have their genitalia exposed. We developed a new, easy-to-use FC insertion device, Quick Foley, that provides an innovative approach to introducing FC while simplifying and minimizing time spent without compromising the sterility. METHODS: We developed an all-in-one disposable FC introducer contains all the necessary components in a single-device-kit. Minimal plastic components are necessary to keep accuracy and consistency, but the rest are made of the paper to minimize plastic waste. The preparation is done by connecting to the drainage bag, spurring the lubricant gel through gel insert, separating the tract, and connecting with the ballooning syringe. For the insertion, after sterilizing the urethral orifice, rotate the control knob to feed FC to the end of the urethra. After ballooning, dissembling of the device is done only by opening and removing the module, then only the FC remains. RESULTS: As the device is all-in-one, there is no need to prearrange the FC tray, simplifies the FC preparation and catheterization procedure. This device not only makes it convenient for the practitioner, but ultimately, it will reduce the psychological discomfort experienced by patient by truncating perineal exposure time. CONCLUSION: We have successfully developed a novel device that reduces the cost and burden of using FC for practitioners while maintaining an aseptic technique. Furthermore, this all-in-one device allows the entire procedure to be completed much more quickly compared to the current method, so this minimizes perineal exposure time. Both practitioners and patients can benefit by this new device.

Urinary Tract Trauma in Cats: Stabilisation, Diagnosis and Management.

PRACTICAL RELEVANCE: Traumatic injury of the urinary tract may be caused by external accidental trauma or due to iatrogenic injury (typically as a result of catheterisation procedures). Thorough patient assessment and careful attention to patient stabilisation are essential, with diagnosis and surgical repair delayed until the patient is stable, if necessary. Treatment depends on the location and severity of the trauma. If diagnosed and treated promptly, the chance of survival of a patient without other concurrent injuries is good. CLINICAL CHALLENGES: Following accidental trauma, at the initial presentation urinary tract injury can be overshadowed by other injuries, but if left undiagnosed or untreated it can lead to serious morbidity and potentially mortality. Many of the surgical techniques described for management of urinary tract trauma can be associated with complications, and so comprehensive communication with the owners is necessary. PATIENT GROUP: The main population affected by urinary tract trauma is young, adult male cats, owing to their roaming behaviour, as well as their anatomy and the resulting increased risk of urethral obstruction and its associated management. AIMS: This article aims to serve as a guide to all veterinarians who treat cats for the diagnosis and management of urinary tract trauma in cats. EVIDENCE BASE: This review summarises the current knowledge available from a number of original articles and textbook chapters in the literature that cover all aspects of feline urinary tract trauma, and is supported by the authors' own clinical experience.

A case of squamous cell carcinoma arising from a suprapubic cystostomy tract in a patient with spinal bifida: Immunohistochemical analysis and literature review.

Introduction: Squamous cell carcinoma arising from a suprapubic cystostomy tract is a rare complication of an indwelling catheter and is caused by long-term inflammation and mechanical irritation. Prognosis is relatively poor. Biomarkers in the cancer pathway have not been investigated. Case presentation: A 61-year-old woman with a 34-year history of suprapubic catheter placement presented with a rapidly growing elevated lesion around the cystostomy site. Tumor biopsy confirmed squamous cell carcinoma. Local excision with partial cystectomy was performed. Multiple metastases were identified 5 months later. The patient died 14 months after the initial treatment. Immunohistochemical analysis of the resected specimen revealed alterations in vascular endothelial growth factor, epidermal growth factor receptor, cyclooxygenase-2, and Ki-67. Conclusion: We encountered a case of squamous cell carcinoma arising from a suprapubic cystostomy tract. Immunohistochemical analysis revealed activation of multiple carcinogenic pathways in cancer cells, including those for angiogenesis, signal transduction by epidermal growth factor receptor, inflammation, and cell proliferation.

Septic shock following ultrasound-guided suprapubic puncture cystostomy: a case report / 中华泌尿外科杂志

A case is presented involving a patient with a history of pelvic fracture who experienced progressive difficulty in urination following the removal of a urethral catheter. Attempt to retain the catheter was unsuccessful, leading to an ultrasound-guided suprapubic puncture cystostomy. Subsequently, the patient developed persistent abdominal pain, distension, nausea, and vomiting. Analysis of turbid greyish-yellow thin purulent fluid obtained during abdominal paracentesis indicated the presence of peritonitis. Urgent surgical exploration revealed that the diversion tube had passed through the abdominal cavity and into the bladder. The entire abdominal cavity was filled with yellowish-thin purulent fluid. Intraoperatively, the patient presented with worsening hypotension, tachycardia, oliguria, and decreased skin temperature, suggestive of septic shock resulting from peritonitis. Prompt management, including antimicrobial therapy, hemodynamic support, and fluid resuscitation, successfully controlled the infectious symptoms, leading to complete recovery. In clinical practice, the emphasis is often placed on assessing injuries to intra-abdominal organs, whereas awareness and understanding of peritoneal injuries remain limited. As a result, postoperative peritonitis is frequently attributed solely to intra-abdominal organ damage, overlooking the potentially grave consequences of pure peritoneal injury. Therefore, it is imperative to enhance our recognition and knowledge regarding peritoneal injuries, enabling timely diagnosis and treatment to prevent the occurrence of complications.

[The mediating effects of self-efficacy between symptom experience and quality of life in prostatic hyperplasia patients after cystostomy].

OBJECTIVE: To evaluate the symptom experience of patients with benign prostatic hyperplasia and bladder fistula. Exploring the mediating effect of self-efficacy on the relationship between symptom experience and quality of life in patients with benign prostatic hyperplasia undergoing long-term indwelling cystostomy. METHODS: This study used a cross-sectional survey design. Patients with prostatic hyperplasia with cystostomy in the Urology department of General Hospital of Eastern Theater Command from January 2020 to February 2023 were selected, and relevant data were collected by IPSS, IIEF-5, HAMD, GSES, and quality of life score scale for statistical analysis. We then construct a structural equation model to evaluate the mediating effect of self-efficacy between symptom experience and quality of life. RESULTS: The average score of IPSS was (22.55±8.26) ; the average score of IIEF-5 was (10.54±4.10) ; the average score of HAMD was (6.82±2.35) ; the average score of self-efficacy was (20.80±8.65) ; and the average score of quality of life was (71.65±12.55) . Symptom experience was significantly negatively correlated with self-efficacy and quality of life( r=－0.496 , P<0.01；r=－0.518 , P<0.01) . Self-efficacy was significantly positively correlated with quality of life( r= 0.412，P<0.05). Symptom experience significantly negatively affected quality of life through self-efficacy (Effect = －0.218，P = 0.014) . CONCLUSION: Self-efficacy is positively correlated with the quality of life of patients with benign prostatic hyperplasia who have long-term indwelling cystostomy tube. Nursing staff can improve the level of self-efficacy of patients by implementing corresponding interventions.

How We Made Exstrophy Bladder Continent and Preserved the Renal Functions.

Purpose: Crucial requirement of exstrophy bladder repair is to make patients continent as well as to preserve kidney functions. We analyzed our patients' data retrospectively to study their continence and to find out the justification behind continence and preservation of renal functions. Patients and Methods: We selected files of 18 fully continent patients from 52 patients operated. Eleven out of 18 patients were presented from beginning and 7 were referred after around 8 to 14 years, as incontinent bladder following good repair of bladder neck and posterior urethra. Eleven were operated with complete primary repair of exstrophy along with pubic osteotomy minimal and were kept on cystostomy track (CT) till augmentation to vent out vesical pressure. In seven patients, we did reduction of caliber of posterior urethra and bladder neck along with CT followed by augmentation after 6 months. Results: All 18 patients are maintaining dry period for 24 h. Two patients had enuresis but are manageable with partial fluid restriction from evening. Seventeen out of 18 patients are maintaining their renal functions. Conclusion: No tension abdominal wall closure with rectus muscle apposition is essential to preserve repaired bladder exstrophy. Osteotomy prevents lateral drag to overcome failure of whole reconstruction. Increased "systolic" vesical pressure from contraction of small bladder might destroy the mechanism of continence and renal functions. Hence, venting of vesical pressure through CT is obligatory till augmentation which is of necessity to be done as early as possible to create a low-pressure continent system.

A custom-made removable appliance for the decompression of odontogenic cysts fabricated using a digital workflow.

OBJECTIVES: This case series aimed to assess the feasibility of a custom-made decompression appliance fabricated using a digital workflow to decompress odontogenic cysts. Additionally, the treated cysts were assessed for volumetric changes. METHODS: A three-dimensional (3D) reconstruction software (CoDiagnostiX version 10.4) was used to obtain the master cast STL (Standard Tessellation Language) file by placing a customized virtual implant to create a recess for the tube of the decompression device. The decompression appliance was planned using Dental Wings Open Software (DWOS). Following rapid prototyping, the tube of the appliance was perforated using round burs. In cases where the appliances were designed to replace teeth, denture teeth were added using the conventional workflow. The appliances were delivered on the day of the cystostomy. Following decompression, cyst enucleation was performed. Cyst volume was assessed by manual segmentation of pre- and post-operative cone-beam computed tomography (CBCT) reconstructions using slice-by-slice boundary drawing with a scissors tool in the 3DSlicer 4.10.2 software. Percentage of volume reduction was calculated as follows: volume reduction/pre-operative volume × 100. RESULTS: Six odontogenic cysts in six patients (5 male, 1 female; age 40 years, range: 15-49 years) with a pre- and post-operative cyst volume of 5597 ± 3983 mm3 and 2330 ± 1860 mm3 respectively (p < 0.05) were treated. Percentage of volume reduction was 58.84 ± 13.22 % following a 6-month-long decompression period. CONCLUSIONS: The digital workflow described in this case series enables the delivery of decompression appliances at the time of cystostomy, thus effectively reducing the volume of odontogenic cysts. The resulting bone formation established a safe zone around the anatomical landmarks; therefore, during enucleation surgery, complications to these landmarks can be avoided.

[Isolated continent urinary diversion: An interesting or often regretted indication?] / Cystostomie continente isolée : une indication intéressante ou que l'on regrette souvent ?

INTRODUCTION: The aim of this study is to evaluate the percentage of patients developing vesical overactivity after the realization of a continent stoma without bladder enlargement. MATERIAL AND METHOD: This is a retrospective monocentric study between January 2007 and April 2021. Patients undergoing an isolated continent urinary diversion for neurological or non-neurological reasons were included. The data collected concerned the clinical symptoms of bladder overactivity and their treatment as well as the pre- and postoperative urodynamic information. RESULTS: During the period, 9 patients were included. The main indications for continent urinary diversion were patients with spinal cord injury. Clinical bladder overactivity was found postoperatively in 78% (7) of the patients, and detrusor overactivity in 57% (4) of them. The main symptoms were urinary incontinence (67%) and pollakiuria (56%, 5 patients). Most of the patients benefited from associated treatments (78% pre- and postoperative), mainly anticholinergic drugs. No patient required botulinum toxin injections preoperatively, compared with 6 (67%) postoperatively. The time of initiation of these injections varied between 3 and 8 months postoperatively. CONCLUSION: Isolated continent urinary diversion seems to induce or increase bladder overactivity. A larger multicentric study is necessary to validate our hypothesis.

Robot-Assisted vs. Open Appendicovesicostomy in Pediatric Urology: A Systematic Review and Single-Center Case Series.

Introduction: Appendicovesicostomy (APV) is the preferred choice of continent catheterizable channels in pediatric urology. The introduction of robot-assisted laparoscopic techniques has been correlated to superior cosmesis and convalescence and is now increasingly implemented for APV procedures. We aimed to perform a systematic review of the literature comparing open vs. robotic APV regarding possible differences in postoperative outcomes and to evaluate these findings with our own initial experiences with robotic APV compared to our previous open procedures. Methods: We evaluated the first five patients undergoing robotic APV at our institution and compared 1-year outcomes with a consecutive series of 12 patients undergoing open APV. In a systematic literature review, we screened studies from PubMed, EMBASE, and CENTRAL comparing open and robotic APV in pediatric urology (current to December 2021) and performed meta-analyses on postoperative outcomes comparing the two groups and evaluated the grade of evidence. Results: We found significantly shortened postoperative length of stay in the robotic group (p = 0.001) and comparable 1-year complication rates in robotic vs. open APV patients. We systematically screened 3,204 studies and ultimately included three non-randomized studies comparing postoperative outcomes of robotic and open APV for quantitative analysis. The open and robotic approaches performed equally well regarding overall postoperative complications, surgical reintervention, and stomal stenosis. Two of the included studies reported comparable stomal continence rates and shortened postoperative length of stay in the robotic group, in agreement with the findings in our own series. Conclusion: Robotic APV is equally safe to the conventional open approach with additional advantages in postoperative hospitalization length.

Suprapubic catheterisation: a study of 1000 elective procedures.

OBJECTIVES: To investigate the risks and long-term outcomes of suprapubic catheter (SPC) insertion in a population predominantly with spinal cord injury. MATERIALS AND METHODS: We used the theatre database at the National Spinal Injuries Centre in Stoke Mandeville Hospital to identify 1000 consecutive SPC insertions from 1998 to 2015. We retrospectively analysed all records for these patients. RESULTS: Follow-up ranged from 4 weeks to 16.45 years (median 3.3 years). Either cystoscopy-guided suprapubic puncture (Lawrence Add-a-Cath trochar) or a direct incision onto a urethral sound (Lowsley retractor) followed by cystoscopy was used for 98% of insertions. Complications graded as Clavien-Dindo IIIb or higher occurred in 0.6% of patients. Return to theatre was necessary in 0.4%, including three laparotomies due to bleeding or misplacement of the catheter, but no bowel injuries occurred. One death occurred within 30 days due to pulmonary embolism. There were no significant differences in outcomes between insertion methods. Tolerance of long-term suprapubic catheterisation was high, despite 59% of cases experiencing mostly minor complications. Tract losses during routine community change and variability in antibiotic prescribing highlighted areas for educational development which could improve patient outcomes. CONCLUSIONS: This study supports the view that the risk of major complications from SPC insertion is lower than previously reported. Minor complications related to the catheter are common in the long term but are generally well tolerated.

Preservation of native sigmoid colon for secondary continent cystostomy after multivisceral transplantation for chronic intestinal pseudo-obstruction.

Chronic intestinal pseudo-obstruction (CIPO) is characterized by severe digestive +/- urinary dysmotility. If the conservative management fails, multivisceral transplantation (MVT) may be needed. However, urinary dysmotility remains after MVT and requires to continue urinary catheterizations and/or drainage. We report on a boy with severe CIPO complicated by (1) chronic intestinal obstruction requiring total parenteral nutrition, decompression gastrostomy, and ileostomy; (2) recurrent line infections; (3) hepatic fibrosis; and (4) distension of the bladder and upper urinary tract, and recurrent urinary infections, leading to non-continent cystostomy for urinary drainage. He underwent MVT at the age of 5 years. The transplant included the liver, stomach, duodenum and pancreas, small bowel, and right colon. The distal native sigmoid colon was preserved. Fifteen months later, he underwent a pull through of the transplanted right colon (Duhamel's procedure), together with a tube continent cystostomy (Monti's procedure) using the native sigmoid. Postoperative course was uneventful, and the remaining ileostomy was closed 3 months later. Five years post-transplant, he is alive and well. He is fed by mouth with complementary gastrostomy feeding at night. He has 3-6 stools per day, with occasional soiling. The cystostomy is used for intermittent urinary catheterization 4 times/day and continuous drainage at night. He is dry, with rare afebrile urinary infections, normal renal function, and un-dilated upper urinary tract. Conclusion: in severe CIPO with urinary involvement, preservation of the distal native sigmoid colon during MVT allows secondary creation of a continent tube cystostomy, which is useful to manage persistent urinary disease.
