RESUMEN
INTRODUCTION: Continent cutaneous urinary diversion (CCUD) is proposed to patients suffering from chronic neurologic retention and undergoing intermittent self-catheterization (ISC). In case of neurogenic detrusor overactivity (NDO), augmentation enterocystoplasty is often required. The aim was to identify the prevalence of urinary stomal and/or urethral leakage in patients who had not undergone enlargement. METHODS: Monocentric, retrospective study of patients who underwent CCUD surgery in a neuro-urological context. Mitrofanoff's, Monti's or Casale's channels were performed. Patients selected had an underactive, stable, or stabilized bladder under adjuvant therapy with proper cystomanometric capacity. Prior or concomitant enterocystoplasty were excluded. Failure was defined as the occurrence of clinical leakage whatever it is through urinary stomal, or urethral. Urodynamic parameters were also reported. RESULTS: Thirty-one patients underwent surgery. Nine women had a concomitant bladder neck sling and 1 urethral closure. The mean follow-up was 7 years. 8/31 (26%) had stomal leakage and 9 urethral leakage (29%). Five spinal cord injured patients (n=14) had stomal leakage (36%) and 6 urethral leakage (43%). Of the 25 postoperative urodynamic parameters, cystomanometric bladder capacity was 419mL (vs. 514mL) and 2 additional patients had de novo NDO (9 vs. 7). DISCUSSION: The morbidity of augmentation enterocystoplasty is weighed against the presence of a well-controlled bladder preoperatively. Our study shows the appearance of leakage in some patients despite a well-balanced bladder, a decrease in mean cystomanometric capacity and an increase in the rate of NDO postoperatively. Good selection criteria for an isolated CCUD should be carefully revised and defined. LEVEL OF EVIDENCE: Grade C - retrospective study.

PURPOSE: We describe long-term outcomes, including UTIs and need for reimplantation, after ureterovesicostomy (UV) as a lasting surgical procedure for children with primary obstructive megaureter (POM). MATERIALS AND METHODS: Children referred to our institution between 2016 and 2023 who underwent refluxing UV were analyzed. POM was defined as hydroureteronephrosis with distal ureteral dilatation > 7 mm and a negative workup for other etiologies of hydronephrosis. We assessed for surgical outcomes, complications, rate of UTI, and improvement in upper tract dilatation. Statistical analyses assessed for change in hydronephrosis metrics over follow-up. RESULTS: Among 183 patients diagnosed with POM, 47 (24%) underwent UV. Median age of presentation, surgery, and follow-up was 2, 9, and 43 months, respectively. A total of 7 patients developed 30-day complications: Clavien-Dindo grade 1 in 2 (transient urinary retention) and grade 2 in 5 (UTIs). During monitoring 14 (30%) developed UTIs and 7 (15%) required ureteral reimplant or UV takedown. After surgery there was a significant decrease in the proportion of patients with high-grade hydronephrosis, anteroposterior renal pelvis diameter, and maximum ureteral dilatation. CONCLUSIONS: Refluxing UV is a safe alternative to cutaneous diversion in POM. Most patients had improvement in upper tract dilatation with an acceptable short-term complication rate and need for reoperation (in comparison to routine later reimplantation). Our experience suggests that monitoring alone after UV is feasible, and that selective subsequent reconstruction is a reasonable strategy.

OBJECTIVES: Low-profile cystostomy tubes provide an alternative to conventional cystostomy tubes with external tubing. Previously, these have been placed surgically involving coeliotomy, cystotomy and cystopexy, or have been used as replacement tubes in existing stoma sites. The purpose of this study is to describe a technique for, and the outcomes of, single-step, non-surgical low-profile cystostomy tube placement. MATERIALS AND METHODS: All cases that had single-step, non-surgical placement of low-profile cystotomy tube attempted at the authors' institutions were included in this study. Data, including success rates, outcomes and complications, were extracted from the medical records. RESULTS: Ten client-owned dogs were inclided. Single-step, non-surgical placement was successful in eight out of 10 dogs, with placement being unsuccessful in two thus necessitating coeliotomy. The median duration that low-profile cystostomy tubes were in place was 7.0 months (range 4 days to 38 months). Seven of the eight dogs required replacement of their cystostomy tube. Mean time until first tube replacement was 103 days (range 13 to 363 days). CLINICAL SIGNIFICANCE: Single-step, non-surgical placement of a low-profile cystostomy tube is a viable alternative to surgical placement. Lack of cystopexy does not appear to result in complications. Conversion to coeliotomy might be required if tube placement is not successful with this technique. Complications seen with non-surgical tube placement such as inadvertent tube removal were similar to those previously reported for surgically placed tubes.

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.

A male child in the first decade of life presented to us with a history of a pelvic fracture and urethral injury resulting from a road traffic accident 4 months prior. He had previously undergone an exploratory laparotomy and suprapubic cystostomy at another medical centre. He was circumcised and exhibited a substantial urethral defect on the retrograde urethrogram, as well as on the micturating cystourethrogram. Following a careful assessment of the patient's and caregivers' expectations, a continent cutaneous catheterisable channel was planned. This procedure involved the use of an anterolateral bladder flap, and continence was achieved through the creation of a Nissen-type seromuscular invagination. Three months postoperatively, the child remains continent, can easily catheterise the stoma and has resumed his education.

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.

PURPOSE: To report our experience and results in terms of complications, reoperation rate and urinary continence with the Salvage Continent Vesicostomy (SCV) technique in pediatric patients with history or need of enterocystoplasty and absent appendix. METHODS: Retrospective review of all patients with a history of a continent catheterizable channel surgery performed in our institution between June 2016 and January 2022. Only patients with a SCV surgery with a minimum 6-month post operative follow up were included in this cohort and divided in group 1 (history of previous bladder augmentation) and group 2 (simultaneous bladder augmentation and SCV). Primary outcome of the study was to assess both continence and postoperative complication rates. Early complications were assessed using the Clavien-Dindo classification (I-V). Late complications were focused on the need of further subfascial revision. RESULTS: 84 patients with a history of a continent stoma creation surgery were identified. In 20 of them (12 males) a SCV was performed. The mean age at surgery was 10.38 (range 4.87-15.6) years and the median postoperative follow-up time was 32 (range 6-64) months. Eleven patients were included in Group 1, while 9 patients in Group 2. Early complications occurred in 4 patients (20%), two of them required a re-intervention (Clavien-Dindo IIIb). Stoma subfascial revision was further required in 2 patient (10%). Continence rate at last follow up was 95%. CONCLUSIONS: In our early experience, the salvage continent vesicostomy has proven to be a simple continent stoma technique with acceptable both continence and complication rates that can be used in selected patients with a history or need of bladder augmentation and absent appendix.

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.

INTRODUCTION: Patients with Congenital Lower Urinary Tract Malformations (CLUTM) have increased risk of post-transplant complications if bladder dysfunction is not addressed. Pretransplant assessment may be difficult if urinary diversion has been previously applied. In case of low capacity and/or low compliance and/or high-pressure overactive bladder, transplantation into a diverted or augmented system may be required. We hypothesised that a bladder optimization pathway may help identify potentially salvageable bladders and prevent unnecessary bladder diversion or augmentation. We propose a structured bladder optimisation and assessment programme for safe transplant and native bladder salvage. MATERIAL AND METHODS: Data of 130 children who underwent renal transplant between 2007 and 2018 were retrospectively collected and analysed. All patients with CLUTM were assessed by urodynamic study. Bladder optimisation: Low compliance bladders were managed with anticholinergics and/or Botulinum toxin A (BtA) injections. Those who had urinary diversion for their pathology underwent a structured assessment and optimisation process with undiversion/anticholinergics/BtA/bladder cycling/Clean Intermittent Catheterisation (CIC)/Suprapubic catheter (SPC) as indicated. Details of medical and surgical management were collected (Figure 1). RESULTS: Between 2007 and 2018, 130 renal transplants were done. Of these, 35 (27%) had associated CLUTM (PUV in 15, neurogenic bladder dysfunction in 16, other pathology in 4) which was managed in our centre. Ten patients needed initial diversion in the form of vesicostomy (2) or ureterostomy (8) to manage primary bladder dysfunction. The median age at transplant was 7.8 years (range 2.5-19.6). After bladder assessment and optimisation, a safe bladder was demonstrated in 5 of 10 with initial diversion leading to transplant into native bladder (without augmentation). Overall, of the 35 patients, 20 (57%) had transplant into native bladder, 11 patients had ileal conduits and 4 had bladder augmentation. Eight required help with drainage: three with CIC, four with Mitrofanoff, and one had reduction cystoplasty. CONCLUSION: With a structured bladder optimisation and assessment programme, safe transplant and 57% native bladder salvage is achievable in children with CLUTM.

BACKGROUND: Pelvic fracture urethral injury (PFUI) occurs in up to 10% of pelvic fractures. There is mixed evidence supporting early endoscopic urethral realignment (EUR) over suprapubic tube (SPT) placement and delayed urethroplasty. Some studies show decreased urethral obstruction with EUR, while others show few differences. We hypothesized that EUR would reduce the rate of urethral obstruction after PFUI. METHODS: Twenty-six US medical centers contributed patients following either an EUR or SPT protocol from 2015 to 2020. If retrograde cystoscopic catheter placement failed, patients were included and underwent either EUR or SPT placement based on their institution's assigned treatment arm. Endoscopic urethral realignment involved simultaneous antegrade/retrograde cystoscopy to place a catheter across the urethral injury. The primary endpoint was development of urethral obstruction. Fisher's exact test was used to analyze the relationship between PFUI management and development of urethral obstruction. RESULTS: There were 106 patients with PFUI; 69 (65%) had complete urethral disruption and failure of catheter placement with retrograde cystoscopy. Of the 69 patients, there were 37 (54%) and 32 (46%) in the EUR and SPT arms, respectively. Mean age was 37.0 years (SD, 16.3 years) years, and mean follow-up was 463 days (SD, 280 days) from injury. In the EUR arm, 36 patients (97%) developed urethral obstruction compared with 30 patients (94%) in the SPT arm ( p = 0.471). Urethroplasty was performed in 31 (87%) and 29 patients (91%) in the EUR and SPT arms, respectively ( p = 0.784). CONCLUSION: In this prospective multi-institutional study of PFUI, EUR was not associated with a lower rate of urethral obstruction or need for urethroplasty when compared with SPT placement. Given the potential risk of EUR worsening injuries, clinicians should consider SPT placement as initial treatment for PFUI when simple retrograde cystoscopy is not successful in placement of a urethral catheter. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

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=ï¼0.496 , P<0.01ï¼r=ï¼0.518 , P<0.01) . Self-efficacy was significantly positively correlated with quality of life( r= 0.412ï¼P<0.05). Symptom experience significantly negatively affected quality of life through self-efficacy (Effect = ï¼0.218ï¼P = 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.

RESUMEN La uretrografía retrógrada es la técnica de referencia (gold standard) utilizada clásicamente para hacer diagnóstico de lesiones de uretra. En este contexto se presenta un caso en el que se realizó tomografía computarizada con reconstrucción 3D con contraste intravenoso y endouretral, pudiendo reconstruir la uretra en toda su extensión en forma tridimensional. De esta manera se arribó al diagnóstico de certeza de la lesión de uretra. Como ventaja del método se menciona la posibilidad de diagnosticar ‒ con un solo estudio por imágenes‒ lesiones de todo el tracto urinario, órganos sólidos, huecos y lesión del anillo pélvico asociados al traumatismo, con una alta sensibilidad y especificidad sin necesidad de requerir otros estudios complementarios.
ABSTRACT Retrograde urethrography is the gold standard method for the diagnosis of urethral injuries. In this setting, we report the use of computed tomography with intravenous injection and urethral administration of contrast medium and 3D reconstruction of the entire urethra. The definitive diagnosis of urethral injury was made. The advantage of this method is the possibility of making the diagnosis of traumatic injuries of the entire urinary tract, solid organs, hollow viscera and of the pelvic ring within a single imaging test, with high sensitivity and specificity, with no need to perform other complementary tests.

INTRODUCTION: In patients with urinary continent channel (UCC) and Malone Antegrade Continent Enema (MACE) procedures, two separate abdominal stomas are needed. The umbilicus is a preferred site for single channel stomas given the ability to conceal the stoma. However, there are no studies describing outcomes of both stomas being created in the umbilicus. We aimed to describe our experience in patients who underwent UCC and MACE stomas both placed in the umbilicus. METHODS: A retrospective review from 2009 to 2020 was performed in our institution for patients who underwent the creation of UCC and MACE stomas simultaneously in the umbilicus. The variation in the technique involves two V-skin shaped flaps in the umbilicus; the MACE and UCC stomas are delivered from both flaps and placed at the right and left side respectively. Patients with greater than 3 months of follow-up were included in the study. RESULTS: There were 17 patients identified with the median age of 13.5 years and a median follow-up of 32.8 months. The mean BMI percentile was 89.5%. Monti technique and split appendix with cecal extension were utilized in 8 (47.1%) and 7 (41.2%) patients respectively and 13 (76.5%) patients required concurrent urological procedures. All channel-related complications occurred within a mean time of 15.7 months. Skin-level stenosis in the MACE occurred in 5 (29.4%) events, and all were successfully managed by placing an indwelling catheter for up to two weeks. There were 2 (11.8%) complications related to UCC, which required subfascial minor surgical revision. The rate of patients with symptomatic UTI decreased 35.3% postoperatively, and no new onset of UTI occurred in patients without a prior history of UTI. During follow-up, all patients remained dry between CIC, however one had occasional leakage related to delay in catheterization. Total fecal continence was achieved in 14 (82.3%) patients. Additionally, 3 (16.6%) patients experienced improvement in fecal continence with sporadic soiling episodes. COMMENTS: Placement of UCC and MACE stomas in the umbilicus demonstrate a percentage of complication of 7/34 (20.6%) with only 2 patients requiring surgical intervention, comparable to the standard. UTI rate decreased in patients with a prior history of UTI. We believe the patients' perspective and degree of satisfaction will fully determine the benefits of this technique. CONCLUSIONS: Simultaneous UCC and MACE stomas placed at the umbilicus showed good functional outcomes and similar complication rates to traditional approach where stomas were placed separately in the abdominal wall.

PURPOSE: To report on the long-term outcomes of vesicostomy in elderly patients with chronic urinary retention. MATERIALS AND METHODS: We conducted a study of 16 elderly patients with chronic urinary retention who underwent Blocksom vesicostomy between April 2010 and March 2021. Postoperative follow-up was conducted every 3 months to check for abnormal findings, such as stoma outlet obstruction, infection, bleeding, bladder prolapse, and bladder stones. The incidence of these findings and the time until they occurred, as well as the rate of achieving a catheter-free status and the time until catheter reinsertion, were then calculated using the Kaplan-Meier curve. RESULTS: The mean age (±standard deviation) of patients whose cases were observed was 78.6 (±7.8) years; the oldest patient was 87 years of age. The study population included 14 male patients and 2 female patients, with a higher number of males. The causes of urinary retention included neurogenic bladder in 12 patients (including patients with 3 spinal cord injury), advanced prostate cancer in 2 patients, and iatrogenic urethral stricture in 2 patients. The average follow-up period was 55.7 months. During follow-up, 14 patients (87.5% of the total) achieved a catheter-free status under conditions that required no additional treatment. Complications were observed in 6 cases (37.5%); among them, two cases required reoperation. All complications were observed within 2 years after surgery. CONCLUSION: Blocksom vesicostomy may become a viable option in the treatment of elderly patients with chronic urinary retention whose symptoms do not improve with medical therapy.

Magnetic compression technique (MCT) is a popular new anastomosis method. In this paper, we aimed to explore the feasibility of use of MCT for performing cystotomy in rabbits. The parent magnets and daughter magnets for rabbit cystostomy were designed and manufactured according to the anatomical characteristics of rabbit lower urinary tract. Twelve female New Zealand rabbits were used as animal models. After anesthesia, a daughter magnet was inserted into the bladder through the urethra, and the parent magnet was placed on the body surface projection of the bladder over the abdominal wall. The two magnets automatically attract each other. Postoperatively, the state of magnets was monitored daily, and the time when the magnets fell off was recorded. Cystostomy with MCT was successfully performed in all twelve rabbits. The mean operation time was 4.46 ± 0.75 min. The magnets fell off from the abdominal wall after a mean duration of 10.08 ± 1.62 days, resulting in the formation of bladder fistula. Macroscopic and microscopic examination showed that the fistula was well formed and unobstructed. The junction between bladder and abdominal wall was tight and smooth. We provide preliminary experimental evidence of the safety and feasibility of cystostomy based on MCT.

OBJECTIVE: To determine the utility of post-operative imaging after ureteroneocystostomy and whether long-term symptom or radiographic surveillance aided in the detection of recurrent obstruction. MATERIALS AND METHODS: Adult patients were identified who underwent a ureteroneocystostomy with or without psoas hitch or Boari flap between January 2012 and June 2021. Patients who underwent a bilateral procedure, had active malignancy or immediate failure, or did not have 6 months of follow-up with 2 imaging studies were excluded. Using the initial imaging study after stent removal, patients were categorized into normal and equivocal groups according to predefined radiologic criteria. Patients were followed longitudinally to determine whether they subsequently developed radiographic evidence of obstruction. Follow up visits were reviewed for patient symptoms suggestive of post-operative obstruction, defined as flank pain, hematuria, or pyelonephritis. RESULTS: One hundred and twelve patients met criteria. Normal and equivocal initial imaging was seen in 99 and 13 patients, respectively. At a mean radiologic follow-up of 32 months, stricture recurrence was identified in 3 patients with normal initial imaging. No patients with initial equivocal imaging demonstrated recurrent obstruction at mean radiologic follow-up of 29 months. All patients with recurrent stricture presented with symptoms of obstruction. Of patients who developed symptoms after ureteroneocystostomy, 13.6% had recurrent stricture. CONCLUSION: Asymptomatic patients after ureteroneocystostomy who had either normal or equivocal post-operative imaging did not benefit from additional radiologic testing in this cohort. All patients that demonstrated failure presented with symptomatic obstruction that warranted imaging. Surgeons may consider restricting surveillance imaging to symptomatic patients after the initial post-operative period.

PURPOSE: The purpose of this study was to investigate the course of bladder evacuation and the predictors of intermittent self-catheterization (ISC) in individuals with neurogenic lower urinary tract dysfunction (NLUTD) during and after primary rehabilitation. METHODS: The patient database of a single spinal cord injury rehabilitation center was screened for patients with NLUTD admitted for primary rehabilitation. Patient characteristics and bladder evacuation details were collected during and after rehabilitation. Binary logistic regression analysis was used to evaluate predictors of ISC: sex, age > 65 years, injury severity, and bladder capacity ≥ 400 ml. RESULTS: Data of 255 men (74.3%) and 88 women (25.7%) with a mean age of 54 ± 19 years were analyzed. Early in rehabilitation, 21.6% of the evaluated individuals used ISC. In 17.8%, the bladder was evacuated by transurethral catheterization (TUC). The proportion of TUC decreased during rehabilitation and dropped below 2% at the last follow-up. In contrast, the proportion of ISC and suprapubic catheterization (SPC) increased to 28% and 12.8%, respectively, during rehabilitation. These proportions increased further thereafter and reached 37.7% and 18.6% for ISC and SPC, respectively. Age and injury severity were significant (p ≤ 0.041) negative predictors, whereas male sex and above-average bladder capacity were positive predictors of ISC. CONCLUSIONS: There is a shift toward bladder evacuation by ISC and SPC during and after primary rehabilitation. Bladder evacuation by ISC, regarded as the gold standard, is less common in individuals > 65 years or with high-level tetraplegia. The optimal bladder evacuation method needs to be established individually, considering all medical and psychosocial factors rather than simply following a guideline.

OBJECTIVES: The aims of this study were to describe the indications for percutaneous pigtail catheter placement in cats requiring urine diversion, and to report the associated intra- and postoperative complications. METHODS: The medical records of cats that underwent percutaneous pigtail catheter placement for urine diversion between January 2011 and May 2021 were retrospectively reviewed. RESULTS: Twenty-five cats were included. Indications for pigtail catheter placement were medical management of obstructive urinary tract disease (n = 12), urinary tract damage after traumatic injury (n = 8) and neurological bladder dysfunction (n = 5). Catheters were in place for a median time of 8.28 days (range 3-27), and the duration of the catheter placement was not different between the medical, traumatic and neurological groups. Ten cats (40%) developed pigtail catheter complications including dislodgement, urine leakage, urinary tract infection and bladder rupture. The majority of complications were easily resolved and did not require surgical intervention. CONCLUSIONS AND RELEVANCE: The results suggest that percutaneous pigtail catheter placement can facilitate urine diversion in both the emergency setting and in the long-term management of urine retention without many complications.
