Endoscopic management of Urolithiasis on a pediatric patient with a solitary kidney and an Ileal conduit

@#Management of nephrolithiasis in patients with urinary diversions pose a unique therapeutic challenge for the following reasons: 1) retrograde ureteral access is difficult to perform through a bowel diversion and 2) percutaneous renal access becomes challenging because of inability to do a retrograde pyelogram. For this reason, image-guided access through a combined ultrasound and fluoroscopic guidance are both necessary. This clinical problem becomes even more complicated when dealing with a solitary functioning kidney. Treatment should be precise in order to avoid any complications that may progress to renal failure. Presented here is a 15-year-old male adolescent who had previously undergone a radical cystectomy with an ileal conduit for a rhabdomyosarcoma of the bladder last 2008, and complained of flank pain, fever and foul-smelling urine. Imaging studies showed left obstructive hydronephrosis with ureterolithiasis and nephrolithiasis, and an atrophic contralateral kidney. A preliminary nephrostomy tube drainage was done to recover renal function, followed later by percutaneous endoscopic stone management. Discussed here are the challenges involved in his therapy as well as the advantages of a stepwise approach including the short-term outcomes.

Bricker ileal conduit vs. Cutaneous ureterostomy after radical cystectomy for bladder cancer: a systematic review

ABSTRACT Purpose: A systematic review of the literature with available published literature to compare ileal conduit (IC) and cutaneous ureterostomy (CU) urinary diversions (UD) in terms of perioperative, functional, and oncological outcomes of high-risk elderly patients treated with radical cystectomy (RC). Protocol Registration: PROSPERO ID CRD42020168851. Materials and Methods: A systematic review, according to the PRISMA Statement, was performed. Search through the Medline, Embase, Scopus, Scielo, Lilacs, and Cochrane Database until July 2020. Results: The literature search yielded 2,883 citations and were selected eight studies, including 1096 patients. A total of 707 patients underwent IC and 389 CU. Surgical procedures and outcomes, complications, mortality, and quality of life were analyzed. Conclusions: CU seems to be a safe alternative for the elderly and more frail patients. It is associated with faster surgery, less blood loss, lower transfusion rates, a lower necessity of intensive care, and shorter hospital stay. According to most studies, complications are less frequent after CU, even though mortality rates are similar. Studies with long-term follow up are awaited.

Simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion: step-by-step video-illustrated technique

ABSTRACT Introduction: One of the most remarkable characteristics of urothelial carcinomas is multifocality. However, occurrence of synchronous bladder cancer and upper urinary tract urothelial cancer (UTUC) is exceptional. Minimally invasive approach for these synchronous tumors was just occasionally reported (1-4). The aim of this video article is to describe step-by-step the technique for simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion (ICUD). Patients and methods: A 66-year-old female presented with synchronous BCG refractory non-muscle invasive bladder cancer and a right-side UTUC. She was a former smoker and had previously been submitted to multiple transurethral resections of bladder tumor, BCG and right distal ureterectomy with ureteral reimplant. We performed a simultaneous laparoscopic right nephroureterectomy and robot-assisted anterior pelvic exenteration with totally intracorporeal ICUD. Combination of robot-assisted and pure laparoscopic approaches was proposed focusing on optimization of total operative time (TOT). Results: Surgery was uneventful. TOT was of 330 minutes. Operative time for nephroureterectomy, anterior pelvic exenteration and ICUD were 48, 135, 87 minutes, respectively. Estimated blood loss was 150mL. Postoperative course was unremarkable and patient was discharged after 7 days. Histopathological evaluation showed a pT1 high grade urothelial carcinoma plus carcinoma in situ both in proximal right ureter and bladder, with negative margins. Twelve lymph nodes were excised, all of them negative. Conclusion: In our preliminary experience, totally minimally invasive simultaneous nephroureterectomy and cystectomy with intracorporeal ICUD is feasible. Pure laparoscopic approach to upper urinary tract may be a useful tactic to reduce total operative time.

Dissecting the role of radical cystectomy and urinary diversion in post-operative complications: an analysis using the American College of Surgeons national surgical quality improvement program database

ABSTRACT Objective: To characterize the contribution of the extirpative and reconstructive portions of radical cystectomy (RC) to complications rates, and assess differences between urinary diversion (UD) types. Materials and Methods: We conducted a retrospective cohort study comparing patients undergoing UD alone or RC+UD for bladder cancer from 2006 to 2017 using ACS National Surgical Quality Improvement Program database. The primary outcome was major complications, while secondary outcomes included minor complications and prolonged length of stay. Propensity score matching (PSM) was utilized to assess the association between surgical procedure (UD alone or RC+UD) and outcomes, stratified by diversion type. Lastly, we examined differences in complication rates between ileal conduit (IC) vs. continent UD (CUD). Results: When comparing RC + IC and IC alone, PSM yielded 424 pairs. IC alone had a lower risk of any complication (HR 0.63, 95% CI 0.52-0.75), venous thromboembolism (HR 0.45, 95% CI 0.22-0.91) and bleeding needing transfusion (HR 0.41, 95% CI 0.32-0.52). This trend was also noted when comparing RC + CUD to CUD alone. CUD had higher risk of complications than IC, both with (56.6% vs 52.3%, p = 0.031) and without RC (47.8% vs 35.1%, p=0.062), and a higher risk of infectious complications, both with (30.5% vs 22.7%, p<0.001) and without RC (34.0% vs 22.0%, p=0.032). Conclusions: RC+UD, as compared to UD alone, is associated with an increased risk of major complications, including bleeding needing transfusion and venous thromboembolism. Additionally, CUD had a higher risk of post-operative complication than IC.

Functional results of hautmann neobladder with chimney modification and wallace ureteroileal anastomosis: initial experience with 22 patients

ABSTRACT Objective: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. Materials and Methods: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45-74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. Results: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. Conclusions: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.

Self-perception, quality of life and ease of catheterization in patients with continent urinary diversion with the mitrofanoff principle

ABSTRACT Purpose: Continent urinary diversion (CUD) with the Mitrofanoff principle stands as an alternative to urethral catheterization by a route other than the urethra. The aim of the study was to determine self-perception of health-related quality of life (HRQoL), ease of catheterization and global and cosmetic outcomes in patient's dependent on Mitrofanoff catheterization. Materials and methods: Records of all patients who underwent CUD with the Mitrofanoff principle between 2012 to 2018 were reviewed. Data were collected and analysed retrospectively from medical charts. We assessed HRQoL with the EuroQol EQ-5D-3L questionnaire, cosmetic and global satisfaction with a questionnaire designed by the reconstructive urology board and ease of catheterization with a Likert questionnaire adapted from the Intermittent Catheterization Difficulty Questionnaire (ICDQ) validated in patients reliant on retrograde CIC. Results: A total of 25 patients requiring CUD with the Mitrofanoff principle between 2012 and 2018 were assessed, the group was composed mainly of: appendiceal conduits 18 patients (72%) and 7 ileal conduits (Yang-Monti) and three of those requiring Casale (Monti Spiral) and 1 a double Monti technique. Median follow-up was 57 months, median age was 30 years. Visual Analogue Scale (VAS) of the EQ-5D-3L reported a Global health score of 86.5%. Fifty nine percent of the patients had no pain or bleeding with catheterizations. Regarding global satisfaction and cosmetic perception 91% were satisfied with their CUD. Conclusions: CUD is associated with good HRQoL, global satisfaction, ease and painless catheterization, adequate self-perception of cosmetic outcomes and a low complication rate, remaining a safe and viable option.

Transvaginal repair of neobladder vaginal fistula with martius flap

ABSTRACT Introduction: Neobladder vaginal fistula (NVF) is a known complication after cystectomy and orthotopic diversion in women, occurring in 3-5% of women. Possible risk factors for fistula formation include compromised tissue vascularity due to surgical dissection and/or radiotherapy, suture line proximity, local tissue recurrence, and injury to the vaginal wall during dissection. The surgical repair of a NVF can be challenging secondary to vaginal shortening, atrophy, local inflammation from chronic exposure to urinary leakage, and the proximity of the neobladder to the anterior vaginal wall. In this video, we present transvaginal repair of a NVF with Martius flap interposition. Materials and Methods: This is the case of a 47 year old woman with a history of radical cystectomy and creation of a Studer pouch secondary to bladder cancer two years prior who subsequently developed a NVF. Evaluation included an office cystoscopy which demonstrated a 3-4mm left-sided neobladder vaginal fistula at the level of the ileal-urethral anastomosis. No pelvic organ prolapse or evidence of bladder cancer recurrence was appreciated. Results: A vaginal approach for the NVF repair was performed with a Martius flap interposition. A water-tight closure was achieved without any intraoperative or immediate postoperative complications. The urethral Foley was removed at 2 weeks and by 4 weeks the patient did not report any urinary leakage. Conclusions: Neobladder vaginal fistula is a rare complication following cystectomy and orthotopic urinary diversion that can be repaired using a transvaginal approach. A Martius flap interposition is important to augment success of the repair. If a transvaginal approach fails a transabdominal approach or conversion to cutaneous diversion may be necessary.

Modified Wallace anastomotic technique reduces ureteroenteric stricture rates after ileal conduit urinary diversion

ABSTRACT Purpose: To compare perioperative outcomes, complications and anastomotic stricture rate in a contemporary series of patients who underwent open radical cystectomy (RC) with modified Wallace anastomotic technique versus traditional ileal conduit. Materials and methods: Study enrolled 180 patients, of whom 140 were randomized and underwent RC; seventy were randomized to group I and the seventy to the group II. For the primary objective, we hypothesized that the rate of ureteroenteric strictures would be at least 20 % lower in the second group. Secondary end points included rate of anastomotic leak, surgical time, deterioration of the upper tract, intraoperative blood loss and patient-reported quality of life (HRQOL). The modified Wallace 1 technique involved eversion of the ureteral plate and bowel mucosa edges, which were anastomosed together in running fashion, while the outher anastomotic wall was augmented with sero-serosal interrupted sutures. Results: The mean (SD) follow-up time was 26.1 (5.7) months in group I and 25.2 (4.8) months in group II, during which, anastomotic stricture was observed in 8 patients (12%) from the first and 2 patients (3%) from the second group (p < 0.05). The anastomotic leakage rate was significantly higher in first group (17% vs. 8.5%, p< 0.05), while patient-reported HRQOL outcomes were similar between groups after the 12 month follow-up period. Conclusions: By using a modified Wallace technique, we were able to significantly lower anastomotic stricture and anastomotic leakage rates, which are major issues in minimizing both short- and long-term postoperative complications.

Concurrent urinary and bowel diversion: Surgical modification with sigmoid colon that avoids a bowel anastomosis

ABSTRACT Objective: Cystectomy with urinary diversion is the gold standard for muscle invasive bladder cancer. It also may be performed as part of pelvic exenteration for non-urologic malignancy, neurogenic bladder dysfunction, and chronic conditions that result in a non-functional bladder (e.g., interstitial cystitis, radiation cystitis). Our objective is to describe the surgical technique of urinary diversion using large intestine as a conduit whilst creating an end colostomy, thereby avoiding a primary bowel anastomosis and to show its applicability with respect to urologic conditions. Materials and Methods: We retrospectively reviewed five cases from a single institution that utilized the described method of urinary diversion with large intestine. We describe operative times, hospital length of stay (LOS), and describe post-operative complications. Results: Five patients with a variety of urologic and oncologic pathology underwent the described procedures. Their operative times ranged from 5 hours to 11 hours and one patient experienced a Clavien III complication. Conclusion: We describe five patients who underwent this procedure for various medical indications, and describe their outcomes, and believe dual diversion of urinary and gastrointestinal systems with colon as a urinary conduit to be an excellent surgical option for the appropriate surgical candidate.

Initial clinical experience and follow-up outcomes of treatment for ureteroileal anastomotic stricture with Allium coated metal ureteral stent / 北京大学学报(医学版)

OBJECTIVE@#To summarize the initial clinical experience and follow-up results of the treatment for ureteroileal anastomotic stricture after radical cystectomy with Allium coated metal ureteral stent.@*METHODS@#From September 2018 to September 2019, 8 patients with ureteroileal anastomotic stricture after radical cystectomy underwent Allium ureteral stent insertion in Peking University People's Hospital and People's Hospital of Daxing District. The preoperative renal pelvis width under ultrasound was collected to evaluate the postoperative hydronephrosis, creatinine and urea nitrogen (BUN) before and after surgery, perioperative infection, and stent-related complications. The serum creatinine and BUN, renal pelvis width under ultrasound, urography and abdominal plain film (KUB) were reviewed at the end of 1, 3, and 6 months and annually postoperatively to observe the stent position and morphology. The long-term stent patency rate, complication rate, renal function and hydronephrosis were followed up and analyzed. The t-test or rank-sum test was used to compare the measurement data of the matched sample from the preoperative to the last follow-up.@*RESULTS@#In the study, 6 cases (7 sides) were ureteral ileal conduit stricture, and 2 cases (3 sides) ureteral orthotopic neobladder stricture. Before surgery, 5 patients underwent long-term indwelling of a single J ureteral stent, with an average indwelling time of (20.6±8.8) months and an average replacement frequency of (3.6±1.3) months/time. The mean width of renal pelvis was (26.5±9.1) mm on preoperative renal ultrasonography. Among them, 6 patients were successfully indwelled with Allium coated metal ureteral stent by retrograde approach, and 2 patients by combination of double-endoscopy and ante-retrograde approach. No surgery-related complications during perioperative period were observed. The mean follow-up period was 9.8 months and Allium stent and ureter remained unobstructed in all the patients at the last follow-up without replacement or removal. Compared with preoperative data, the mean width of renal pelvis and mean blood urea nitrogen (BUN) in the last follow-up period were significantly reduced [(26.5±9.1) mm vs. (13.4±2.5) mm, P=0.008; (11.6±2.3) mmol/L vs. (10.2±2.2) mmol/L, P=0.017], however, there were no significant differences in the average serum creatinine or hemoglobin (P>0.05). Ureteroileal anastomotic re-stricture and other stent-related complications were not observed in all the patients by antegrade urography.@*CONCLUSION@#Allium coated metal ureteral stent could be used for the treatment for ureteroileal anastomotic stricture, which could maintain relatively long-term patency rate and protect renal function. The indwelling time was longer and it could improve quality of life of patients.

Uso do Princípio de Mitrofanoff com Técnica de Yang-Monti para Derivação Urinária: Relato em Paciente Jovem / Use of the mitrofanoff principle and Yang-Monti Technique for urinary diversion in a young patiente: case report

Objetivo: relatar o caso de uma paciente submetida a cirurgia de derivação urinária utilizando o princípio de Mitrofanoff com a técnica de Yang-Monti. Caso clínico: paciente, feminino, 26 anos, apresentou- -se com queixas de dor para realização de sondagem vesical por sequela de bexiga neurogênica subsequente a ressecção prévia de tumor medular. Após falha medicamentosa, decidiu-se pela urostomia a fim de formar um conduto cateterizável no abdome, seguindo o princípio de Mitrofanoff. Durante o ato cirúrgico, houve aposição do apêndice cecal na cúpula da bexiga objetivando anastomosar sua extremidade distal na cicatriz umbilical. Entretanto, devido à sua falta de comprimento, optou-se por alongar o conduto com um segmento intestinal remodelado pela técnica de Yang-Monti. Comentários: o princípio de Mitrofanoff com a técnica de Yang-Monti, utilizando segmentos intestinais remodelados devido à incompatibilidade do apêndice cecal, demonstrou-se segura e efetiva para o tratamento da incontinência urinária.

Objective: To report the case of a patient submitted to a urinary diversion surgery using the Mitrofanoff principle with the Yang-Monti technique. Clinical case: A 26-years-old patient presented with complaints of pain for bladder catheterization due to a neurogenic bladder sequel after previous spinal tumor resection. After drug-therapy failure, urostomy was decided to form a catheterizable conduit in the abdomen, using the Mitrofanoff principle. During the surgical procedure, the appendix of the cecal was affixed to the dome of the bladder in order to anastomosis its distal part to the umbilical scar. However, due to its lack of length, it was decided to lengthen the conduit with an intestinal segment remodeled by the Yang-Monti technique. Comments: The Mitrofanoff principle associated to the Yang-Monti technique using remodeled intestinal segments, due to the incompatibility of the cecal appendix, proved to be a safe and effective procedure for the treatment of urinary incontinence.

The significance of preoperative estimated glomerular filtration rate on survival outcomes in patients who underwent radical cystectomy and non-continent urinary diversion

ABSTRACT Purpose To evaluate the influence of preoperative renal function on survival outcomes in patients who underwent radical cystectomy (RC) with non-continent urinary diversion (UD). Materials and Methods A total of 132 patients with bladder cancer who underwent RC with non-continent UD due to urothelial carcinoma from January 2006 toMarch 2017 at our tertiary referral center were retrospectively evaluated. Patients were divided into 2 groups as those with estimated glomerular filtration rate (eGFR) <60mL/min/1.73 m2 and ≥60mL/min/1.73 m2 according to preoperative eGFR levels. Patients' characteristics, preoperative clinical data, operative data, pathologic data, oncologic data and complications were compared between the groups. Results The mean age was 64.5±8.7 (range: 32 - 83) years and the median follow-up was 30.9±31.7 (range: 1-113) months. There were 46 patients in Group 1 and 86 patients in Group 2. There was no difference in cancer-specific mortality (45.6% for group 1 and 30.2% for group 2, p=0.078) and survival (56.8±8.3 months for group 1 and 70.5±5.9 months for group 2, p=0.087) between the groups. Overall mortality was higher (63% for group 1 and 40.7% for group 2, p=0.014) and overall survival (43.6±6.9 months for group 1 and 62.2±5.8 months for group 2, p=0.03) was lower in Group 1 compared to Group 2. Conclusions Overall mortality was higher and overall survival was lower in patients with preoperative eGFR <60mL/s. More patients had preoperative hydronephrosis with eGFR< 60mL/s.

HRQOL related to urinary diversion in Radical Cystectomy: a systematic review of recent literature

ABSTRACT Introduction: The health-related QoL is a patient-centered evaluation covering several aspects. This evaluation seems to be particularly important in patients submitted to radical cystectomy (RC) and urinary diversion with ileal conduit (IC) or a neobladder (NB). Objective: Review all recent data comparing QoL outcomes after radical cystectomy with NB and IC diversions. Evidence Acquisition: A systematic search in PubMed/Medline, Embase, and Cochrane databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement in December 2018. All articles published from January 01, 2012 to December 31, 2018, were included. A study was considered relevant if it compared QoL outcomes using validated questionnaires (EORTC QLQ C30, FACT-G, FACT-BL, FACT-VCI, and BCI). Evidence Synthesis: In 11 included studies, a total of 1389 participants were accounted (730 NB and 659 IC cases). The studies were conducted in 8 different countries, two were prospective, and none was randomized. There were two studies favoring results with a neobladder, 3 with incontinent diversion and 6 with no differences. The EORTC-QLQ-C30 was the most used instrument (5 studies) followed by FACT VCI and BCI (3 studies each). Given the heterogeneity of data and lack of prospective studies, a meta-analysis was not performed. Conclusion: No superiority of one urinary diversion was characterized. It seems that the choice must be individualized with an extensive preoperative orientation of the patient and their relatives. That will probably influence how the patient accepts the new condition.

Laparoscopic radical cystectomy with intracorporeal ileal conduit: one center experience and clinical outcomes

ABSTRACT Purpose: To introduce our experience with intracorporeal ileal conduit and evaluate the safety and feasibility of this endoscopic urinary diversion. Materials and Methods: Between March 2014 and July 2017, thirty-six consecutive patients underwent laparoscopic radical cystectomy with intracorporeal ileal conduit. Patients' demographic data, perioperative data, 90-days postoperative outcomes and complications were collected. This cohort were divided into two groups of 18 patients each by chronological order of the operations to facilitate comparison of clinical data. Data were evaluated using the students' T test, Mann-Whitney test and Fisher's Exact test. Results: All surgeries were completed successfully with no conversion. Median total operating time and median intracorporeal urinary diversion time were 304 and 105 minutes, respectively. Median estimated blood loss was 200 mL, and median lymph node yield was 21. Twenty-six Clavien grade < 3 complications occurred within 30-days and 9 occurred within 30-90 days. Five Clavien grade 3-5 complications occurred within 30 days. No statistically significant differences were found between the two groups except for intracorporeal urinary diversion time. At median follow-up of 17.5 (range 3-42) months, 6 patients experienced tumor recurrence/metastasis and 4 of these patients died. Conclusions: Intracorporeal ileal conduit following laparoscopic radical cystectomy is safe, feasible and reproducible. With the accumulation of experience, the operation time can be controlled at a satisfactory level.

Complicaciones de las derivaciones urinarias heterópicas no continentes: Ureterostomías cutáneas vs conducto ileal / Complications of Non-continent Heteropic Urinary Derivations: Skin Ureterostomies vs Ileal Duct

Introducción Y Objetivos Las derivaciones del tracto urinario abarcan una amplia gama de técnicas quirúrgicas, siendo la causa más frecuente para su uso la patología urotelial maligna. De las derivaciones urinarias no continentes heterótopicas las más utilizadas son el conducto ileal y las ureterostomias cutáneas. La elección de la técnica dependerá de la patología de base, las condiciones del paciente y la experiencia del cirujano. El objetivo de este trabajo es determinar las complicaciones tempranas (≤30 días) y tardías (>30 días) de derivaciones urinarias heterópicas no continentes (DUHNC) tipo conducto ileal (CI) vs ureterostomias cutáneas (UC). Métodos Se realizó un estudio descriptivo retrospectivo de los pacientes llevados a DUHNC tipo CI o UC, desde enero del 2008 a julio del 2016, en un centro de referencia para patología oncológica. Se evaluó: edad, género, comorbilidades, escala de Karnofsky, patología quirúrgica, sangrado, ASA, tiempo quirúrgico, estancia hospitalaria, complicaciones tempranas y tardías. Resultados De los 70 pacientes incluidos, 26 con UC y 44 con CI, prevaleciendo el género masculino en ambos grupos. El promedio de edad fue de 66 y 63 años respectivamente y el indice Karnofsky en todos los pacientes fue superior al 90%. La causa más frecuente fue patología maligna de vejiga. El tiempo quirúrgico fue mayor en los pacientes del CI, siendo estadísticamente significativo (p = 0.000). El sangrado fue similar en ambas técnicas quirúrgicas requiriendo transfusión de hemoderivados el 92,3% de los pacientes con UC y 88,6% de los CI. La estancia hospitalaria no tuvo diferencias. En cuanto a las complicaciones tempranas, la más frecuente en ambos grupos fue el choque hipovolémico (61% UC y 58% CI). De las complicaciones tardías la sepsis urinaria prevaleció en ambos grupos (34% y 18% respectivamente) y la estrechez del estoma y la anastomosis ureteroileal se presentaron en las UC y en los CI respectivamente. La mortalidad en el transoperatorio fue del 12,8%. Conclusiones Las DUHNC como las ureterostomias cutáneas o el conducto ileal son técnicas quirúrgicas con tasas de sangrado, transfusión y estancia hospitalaria similares, pero con una menor proporción de complicaciones tanto tempranas como tardías en los pacientes llevados a conducto ileal

Introduction and Objectives The derivations of the urinary tract cover a wide range of surgical techniques, being the most frequent cause for its use the malignant urothelial pathology. Of the urinary diversions, the heterotopic continents are the ileal conduit and the cutaneous ureterostomies. The choice of technique will depend on the underlying pathology, the patient's conditions and the experience of the surgeon. The aim of this study is to determine the early complications (≤30 days) and late complications (> 30 days) of noncontinental heteropic urinary diversions (NHUD) type ileal conduit (IC) vs cutaneous ureterostomies (CU). Methods A retrospective descriptive study was conducted of patients referred to NHUD type CI or CU, from January 2008 to July 2016, in a referral center for oncological pathology. We evaluated: age, gender, comorbidities, Karnofsky scale, surgical pathology, bleeding, ASA, surgical time, hospital stay, early and late complications. Results Of the 70 patients included, 26 with CU and 44 with IC, the male gender prevailing in both groups. The average age was 66 and 63 years respectively and the Karnofsky index in all patients was over 90%. The most frequent cause was malignant pathology of the bladder. Surgical time was higher in IC patients, being statistically significant (p = 0.000). Bleeding was similar in both surgical techniques requiring transfusion of blood products 92.3% of patients with CU and 88.6% of IC. The hospital stay did not differ. Regarding the early complications, the most frequent in both groups was hypovolemic shock (61% CU and 58% CI). Of the late complications, urinary sepsis prevailed in both groups (34% and 18% respectively) and the narrowing of the stoma and the ureteroileal anastomosis were present in the CU and in the IC, respectively. The mortality in the transoperative period was 12.8%. Conclusions NHUD such as cutaneous ureterostomies or ileal conduit are surgical techniques with similar rates of bleeding, transfusion and hospital stay, but with a lower proportion of complications both early and late in patients taken to the ileal conduit.

Estudo descritivo e abordagem qualitativa, com 19 homens com derivações urinárias, a partir de 18 anos que estavam internados na unidade de urologia ou no ambulatório, de uma instituição hospitalar universitária situada no município do Rio de Janeiro. Utilizou-se como instrumento de coleta de dados a entrevista semiestruturada e para a análise dos dados foi aplicada a técnica de análise de conteúdo. Através da análise dos dados emergiram duas categorias: percepção dos homens sobre o autocuidado em decorrência da derivação urinária permanente e Os impactos da derivação urinária permanente na vida do homem e a educação em saúde nesse contexto. Os resultados evidenciam uma percepção fragmentada sobre as práticas de autocuidado com a derivação urinária permanente, influenciada principalmente pelo acesso ao conhecimento, pelo contexto cultural e pelos conflitos pessoais vividos. A análise apontou um impacto direto na rotina diária e profissional dos participantes, levando a incertezas, dúvidas e medo. Em relação as ações de cuidados diários realizados aponta-se a forte atuação da companheira, fortalecendo o cuidar feminino. Quanto ao profissional de enfermagem, destaca-se a necessidade de uma assistência qualificada, que vá além das ações tecnicistas e o seu papel no suporte das orientações necessárias ao autocuidado voltado a derivação urinária permanente. Conclui-se que a qualidade de vida do homem portador de uma derivação urinária permanente relaciona-se intimamente com o suporte profissional ofertado, com o relacionamento interpessoal vivido e como ele enfrenta as novas adaptações baseado na sua cultura e no seu contexto socioeconômico. E que a assistência de enfermagem a luz da teoria do autocuidado de Orem, fornece base para um processo de autocuidado bem sucedido e científico, através de orientações necessárias a qualidade de vida desses homens.

This is a study whose object is the men with permanent urinary diversion and the perception of self-care. With the general objective (The general objective is): to understand the perception of men with a permanent urinary shunt about self-care. And as specific objectives: to identify men's perception of self-care; to analyze the perception of men with permanent urinary diversion on self-care and to discuss the impact of a permanent urinary diversion on men's life from the perspective of self-care. Descriptive study and qualitative approach, with 19 men with permanent urinary diversions, from 18 years who were hospitalized in the urology unit or in the outpatient unit, of a university hospital institution located in the city of Rio de Janeiro. The semi-structured interview was used as a data collection instrument and the content analysis technique was applied for data analysis. Through the data analysis, two categories emerged: men's perception of self-care as a result of permanent urinary diversion and the impacts of permanent urinary diversion on human life and health education in this context. The results show a fragmented perception about self-care practices with permanent urinary diversion, influenced mainly by access to knowledge, cultural context and personal conflicts experienced. The results show a fragmented perception about self-care practices with permanent urinary diversion, influenced mainly by access to knowledge, cultural context and personal conflicts experienced. The analysis showed a direct impact on the daily and professional routine of the participants, leading to uncertainties, doubts and fear. Regarding the daily care actions performed, the companion's strong performance is shown, strengthening the female care. As for the nursing professional, the need for a qualified care that goes beyond the technicist actions stands out and their role in supporting the necessary guidelines for self-care aimed at permanent urinary diversion. It is concluded that the quality of life of the man with a permanent urinary diversion is closely related to the professional support offered, the interpersonal relationship lived and how he faces the new adaptations based on his culture and socioeconomic context. And that nursing care in the light of Orem's self-care theory provides the basis for a successful and scientific self-care process through necessary guidance to the quality of life of these men.

Penile Prosthesis Infection: Myths and Realities

Penile prosthesis infection is the most significant complication following prosthesis implant surgery leading to postoperative morbidity, increased health care costs, and psychological stress for the patient. We aimed to identify risk factors associated with increased postoperative penile prosthesis infection. A review of the literature was performed via PubMed using search terms including inflatable penile prosthesis, penile implant, and infection. Articles were given a level of evidence score using the 2011 Oxford Centre for Evidence-Based Medicine Guidelines. Multiple factors were associated with increased risk of post-prosthesis placement infection (Level of Evidence Rating) including smoking tobacco (Level 1), CD4 T-cell count 8.5 (Level 2). Factors with no effect on infection rate include: preoperative cleansing with antiseptic (Level 4), history of prior radiation (Level 3), history of urinary diversion (Level 4), obesity (Level 3), concomitant circumcision (Level 3), immunosuppression (Level 4), age >75 (Level 4), type of hand cleansing (Level 1), post-surgical drain placement (Level 3), and surgical approach (Level 4). Factors associated with decreased rates of infection included: surgeon experience (Level 2), “No Touch” technique (Level 3), preoperative parenteral antibiotics (Level 2), antibiotic coated devices (Level 2), and operative field hair removal with clippers (Level 1). Optimization of pre-surgical and intraoperative risk factors is imperative to reduce the rate of postoperative penile prosthesis infection. Additional research is needed to elucidate risk factors and maximize benefit.
