Caracterización de pacientes con antecedente de colposuspensión de Burch que consultan en uroginecología / Characterization of patients with a background of Burch colposuspension consulting in urogynecology

INTRODUCCIÓN Y OBJETIVOS: La incontinencia de orina de esfuerzo (IOE) es una patología muy frecuente. El tratamiento estándar corresponde al uso de cintas medio uretrales. Dentro de las técnicas quirúrgicas clásicas se encuentra la colposuspensión de Burch (CSB), poco frecuente en la actualidad. El objetivo de este estudio es describir las características de las pacientes con antecedentes de una CSB que consultan en la unidad de Uroginecología. MÉTODOS: Revisión tipo transversal de los datos ingresados a la unidad de Uroginecología del Hospital Dr. Sótero Del Río desde 2007 al 2019. Análisis descriptivo de los antecedentes de las pacientes con antecedente de CSB. RESULTADOS: Durante el periodo analizado, 63 pacientes presentaban antecedentes de CSB. La edad promedio fue 68 años, 88% eran post menopáusicas, 60% fueron sometidas a histerectomía y 24% a cirugías por prolapso (POP). La paridad promedio fue 3 hijos, 15% tuvieron al menos un parto por fórceps. Un 51% consultó por IOE, 54% por vejiga hiperactiva (VH) y 56% por sensación de bulto o peso. El 38% consultó por incontinencia de orina mixta, 37% por IOE + POP y 41% por VH + POP. 22% fueron reoperadas, 16% por medio de TVT y 6% por TOT. CONCLUSIONES: El antecedente de CSB es infrecuente en nuestra población. Similar a lo descrito en la literatura, más de un 50% de las pacientes consultó por síntomas de recurrencia y por complicaciones como POP y VH. Próximos estudios deberían evaluar si el antecedente de CSB es un factor de riesgo de complicaciones quirúrgicas o recurrencia.

INTRODUCTION AND OBJECTIVES: Stress urinary incontinence (SUI) is a common pathology. The standard treatment corresponds to the mid urethral slings. Among the classic surgical techniques is Burch colposuspension (CSB), currently rare. The objective of this study is to describe the characteristics of the patients with a previous history of CSB who consult in the Urogynecology unit. METHODS: Cross sectional review of the data of all the patients admitted to the Urogynecology unit of the Dr. Sótero Del Río Hospital from 2007 to 2019. Descriptive analysis of the antecedents of the patients with a history of CSB. RESULTS: During the analyzed period, 63 patients had a history of CSB. The average age was 68 years. 88% were postmenopausal, 60% underwent hysterectomy, and 24% underwent prolapse (POP) surgery. The average parity was 3, 15% had at least one forceps delivery. 51% consulted for SUI, 54% for overactive bladder (OAB) and 56% for sensation of lump or weight. 38% consulted for mixed urine incontinence, 37% for SUI + POP and 41% for OAB + POP. 22% were reoperated, 16% through TVT and 6% through TOT. CONCLUSION: The history of CSB is infrequent in our population. Similar to that described in the literature, more than 50% of the patients consulted for recurrence symptoms and complications such as POP and OAB. Future studies should assess whether a history of CSB is a risk factor for surgical complications or recurrence.

Complicaciones en posoperatorio inmediato de cirugía uretral anterior; ¿existe relación con la recaída? / Early complications in urethral anterior surgery; is there any relationship with recurrence?

INTRODUCCIÓN/OBJETIVO: La estrechez uretral puede causar síntomas miccionales, dolor, disfunción vesical y eyaculatoria. La tasa de complicaciones en uretroplastía anterior es baja. El principal objetivo es evaluar complicaciones del posoperatorio (pop) inmediato (dentro de los 30 días pop). El objetivo secundario es valorar la relación entre complicaciones y la tasa de recaída. MATERIALES Y MÉTODO: Se realizó una revisión retrospectiva de las uretroplastías anteriores realizadas entre octubre del 2012 y junio del 2017. Se valoró: reinternación, reingreso a cirugía, infarto agudo de miocardio, tromboembolismo de pulmón, trombosis venosa profunda, óbito, infecciones, dehiscencia de herida, hematomas, sangrados, etc. Se definió recaída a la necesidad de realizar cualquier instrumentación uretral secundaria a la uretroplastía. Las variables se analizaron estadísticamente con Chi square y Mann-Whitney U test. RESULTADOS: Se incluyeron 92 pacientes, con un seguimiento mínimo de 12 meses. Las edades fueron de 18 a 88 años (mediana, 61,5 años). En 58 pacientes, se utilizaron transferencia de tejidos (27 injertos y 31 colgajos). La longitud de la estrechez fue desde 1-15 cm (media, 3,25 cm). La iatrogénica (56%) fue la etiología más frecuente. 56 pacientes (63%) tenían tratamientos previos. La tasa de complicaciones pop inmediato fue del 32%, las infecciones fueron las más frecuentes. Según Clavien, se clasificaron: I: 40%; II: 47%; III: 10%; IV: 3%. Hubo 17 recaídas (18%), 13 dentro de los primeros 6 meses del pop. De los pacientes que presentaron complicaciones, recayó el 23%; solo 16% de los que no las presentaron (p: 0,4). Aquellos pacientes con complicaciones graves presentaron mayor tasa de recaída (p: 0,2). CONCLUSIÓN: La tasa de complicaciones pop inmediata de uretroplastía anterior fue de 32%; las infecciones fueron las más frecuentes. La mayoría fue Clavien I y II. La recaída fue mayor en aquellos pacientes que sufrieron complicaciones en pop inmediato.

Laparoscopic and robotic urology surgery during global pandemic COVID-19

ABSTRACT Known laparoscopic and robotic assisted approaches and techniques for the surgical management of urological malignant and benign diseases are commonly used around the World. During the global pandemic COVID-19, urology surgeons had to reorganize their daily surgical practice. A concern with the use of minimally invasive techniques arose due to a proposed risk of viral transmission of the coronavirus disease with the creation of pneumoperitoneum. Due to this, we reviewed the literature to evaluate the use of laparoscopy and robotics during the pandemic COVID-19. A literature review of viral transmission in surgery and of the available literature regarding the transmission of the COVID-19 virus was performed up to April 30, 2020. We additionally reviewed surgical society guidelines and recommendations regarding surgery during this pandemic. Few studies have been performed on viral transmission during surgery. No study has been made regarding this area during minimally invasive urology cases. To date there is no study that demonstrates or can suggest the ability for a virus to be transmitted during surgical treatment whether open, laparoscopic or robotic. There is no society consensus on restricting laparoscopic or robotic surgery. However, there is expert consensus on modification of standard practices to minimize any risk of transmission. During the pandemic COVID-19 we recommend the use of specific personal protective equipment for the surgeon, anesthesiologist and nursing staff in the operating room. Modifications of standard practices during minimally invasive surgery such as using lowest intra-abdominal pressures possible, controlled smoke evacuation systems, and minimizing energy device usage are recommended.

The outcomes of mini-laparoscopic pyeloplasty in children - brazilian experience

ABSTRACT Objetive Pelvicureteric junction (PUJ) obstruction is the main cause of hydronephrosis in childhood. Open pyeloplasty has been the gold standard treatment of this condition with success rate above 90%. The role of laparoscopic pyeloplasty (LP) in children is less well defined and has slowly emerged as an alternative procedure. We report outcomes of our initial experience with LP in 38 children from 2 months of age. Materials and Methods From June 2015 to December 2017 38 children aged 2-60 months (mean age 1.7 years) underwent LP for correction of PUJ obstruction. The mean pre operative anteroposterior diameter of the renal pelvis (APD) was 43,5mm and all patients had hydronephrosis (APD 21.4-76 mm) and obstructed curve on diuretic renogram. Anderson-Hynes pyeloplasty was the performed technique. Results are reported. Results Mean operative time was 107 minutes (70-180) with no conversion to open procedure. Pain control was needed mainly in the first 12hs. Mean hospitalization was 2 days (1-5). There were complications in 5 children not affecting the final outcome. Two patients had a re-obstruction requiring a second procedure with good result. The mean follow up was 18 months (13-36). The mean reduction on the postoperative APD was 41% - p<0,001 (end APD 5 to 41mm). Overall success rate was 94,7%. All children had good cosmetic results. Conclusions This is a small series limited by short follow up, however its data suggest that LP has good functional and cosmetic results, not compromising the success of the open procedure, regardless patient age.

Assessment of long term outcomes after buccal mucosal graft urethroplasty: the impact of chronic kidney disease

ABSTRACT Objectives To compare and assess various outcomes and success of buccal mucosal graft urethroplasty (BMGU) in patients with CKD versus patients having normal renal function. Material and Methods This was a retrospective, single centre study, during period 2013 to 2017. Patients were grouped into two groups. Group 1 had patients with estimated Glomerular Filtration Rate (eGFR)>60mL/min/1.73m2 while group 2 had patients with eGFR <60mL/min/1.73m2. eGFR was calculated according to the MDRD equation. The two groups were compared with regard to various outcomes like length, location of stricture, technique of graft placement, intra-operative blood loss (haemoglobin drop), duration of hospital stay, post-operative complications and recurrence. Results A total of 223 patients were included in study with group 1 had 130 patients and group 2 had 93 patients. Mean age of patients with CKD were higher (47.49 years versus 29.13 years). The mean follow-up period was comparable between both groups (23.29 months and 22.54 months respectively). Patients with CKD had more post-operative Clavien Grade 2 or higher complications (p=0.01) and a greater recurrence rates (p<0.001) than in non-CKD patients. On multivariate analysis, age and CKD status was significant predictor of urethroplasty success (p=0.004) (OR= 14.98 (1.952-114.94, 95% CI). Conclusions CKD patients are more prone to post-operative complications in terms of wound infection, graft uptake and graft failure and higher recurrence rates following BMGU.

Comparison of the outcomes of laparoscopic pyeloplasty with and without concomitant pyelolithotomy

ABSTRACT Objective We aimed to evaluate the results of laparoscopic pyeloplasty with concomitant pyelolithotomy and compare results with a cohort of patients undergoing laparoscopic pyeloplasty without pyelolithotomy. Materials and Methods We retrospectively reviewed records of 43 patients undergoing transperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty between December 2012 and July 2018 at our department. Eighteen patients (42%) underwent laparoscopic pyeloplasty with concomitant pyelolithotomy. The results of patients with renal stones were compared with 25 matched patients undergoing laparoscopic pyeloplasty without concomitant renal stones. Demographic data, operative and stone parameters were compared between the groups. Results The groups were similar regarding to demographic characteristics. All operations were completed laparoscopically with no conversions to open surgery. In 3 cases without renal stones and 15 cases with renal stones, transposition of the ureter due to crossing vessels was performed. The mean stone size was 13±5.24 mm, and the median number of stones was 1 (1-18). The success of laparoscopic pyeloplasty with and without pyelolithotomy was 93.3% and 92.9%, respectively, as confirmed by negative diuretic renogram at postoperative 3rd months. Overall stone-free rate after laparoscopic pyelolithotomy was 93.3%. Mean operative time was 222.6765.71 minutes vs. 219.11±75.63 minutes for the pyeloplasty with concomitant pyelolithotomy vs. pyeloplasty, respectively (p=0.88). Conclusions Laparoscopic pyeloplasty with concomitant pyelolithotomy is a safe and effective intervention with associated good cosmetic results and high stone-free rates without significant increase in operative time or complications.

A census of laparoscopic and robotic urological practice: a survey of minimally invasive surgery department of the Brazilian Society of Urology

ABSTRACT Minimally invasive urologic surgery has been developing in Brazil and now is a routine part of care in many regions and patients with different conditions benefit from it. Training in laparoscopic and robotic surgery has evolved and concerns exist both over the quality of surgical training and the practical effect on results of the urological training. This is an unprecedented study which undertook a census to determinate the current state of laparoscopic and robotic urological practice and to know the mains barriers to adequate practice in Brazil. In august 2017, surveys, consisting of an anonymous questionnaire with 15 questions, were sent via internet to the mailing list of the Brazilian Society of Urology (SBU). With these data, activities related to laparoscopy and robotic surgery of our urologists and the mains difficulties and barriers to practice laparoscopy and robotic surgery were evaluated. In our survey, 413 questionnaires were completed. Majority of the responders were currently working in the southeast region of Brazil (52.1%) and 75.5% of the surgeons performed laparoscopic surgery while, only 12.8%, robotic surgery. The lack of experience on the technique and the lack of equipment were the mains barriers and difficulties for not executing laparoscopic and robotic surgeries, respectively. Proper longitudinal training and access to good equipment in minimally invasive surgery are still barriers for urologists in our country.

Nonsecretory intestinocystoplasty: postoperative outcomes of 25 years

ABSTRACT Objective The objective of bladder augmentation (BA) is to create a low-pressure reservoir with adequate capacity. Despite its benefits, the use of intestinal patches in bladder enlargement provides a high risk of developing complications and BA with demucosalised bowel represents a potential alternative. Therefore, this study evaluated urological parameters and long-term clinical follow-up of patients submitted to non-secretory BA in a single center with 25 years of experience. Materials and Methods Patients treated with BA underwent urological evaluation, which included history, physical examination and urodynamic study. The main urodynamic parameters (bladder capacity and bladder compliance) were assessed in the pre and postoperative moments, and compared by the Wilcoxon Signed Rank test. The main long-term complications were described. Results 269 patients (mean age 14±13 years, 47% male) underwent BA with the use of demucolised intestinal segments. Among the patients in the sample, 187 (69.52%) had neurogenic bladder, 68 (25.28%) had bladder exstrophy, nine had tuberculosis (3.34%), four had a posterior urethral valve (1.49%) and one with hypospadia (0.37%). After the surgical procedure, a significant increment in both urodynamic parameters was found, with a 222% increase in bladder capacity and 604% in bladder compliance (p <0.001 in both analyzes). Mean follow-up time ranged from 2 to 358 months, with a median of 72 months (IQR 74-247). Among all patients, 5 presented spontaneous perforation. Conclusion The study showed statistically significant increase in both compliance and bladder capacity after non-secretory BA, with a low rate of severe complications.

Balloon dilation for failed pyeloplasty in children?

ABSTRACT Objective: Pyeloplasty is considered the gold standard treatment for ureteropelvic junction obstruction (UPJO). However, the failure rate of pyeloplasty is as high as 10% and repeat pyeloplasty is more difficult. This study aimed to evaluate the efficacy of balloon dilatation for failed pyeloplasty in children. Materials and Methods: Between 2011 and 2017, 15 patients, aged 6 months to 14 years, were treated with balloon dilation for restenosis of UPJO after a failed pyeloplasty. Ultrasound and intravenous urography were used to evaluate the primary outcome. Success was defined as the relief of symptoms and improvement of hydronephrosis, which was identified by ultrasound at the last follow-up. Results: All patients successfully completed the operation, 13 patients by retrograde approach and 2 patients by antegrade approach. Thirteen patients were followed for a median of 15 (4 to 57) months and 2 patients were lost to follow-up. Resolution of the hydronephrosis was observed in 5 cases. The anteroposterior diameter (APD) of the pelvis decreased by an average of 12.4 ± 14.4mm. Eight patients needed another surgery. The average postoperative hospital stay was 1.78 ± 1.4 days. Two patients experienced fever after balloon dilation. No other complications were found. Conclusions: Balloon dilatation surgery is safe for children, but it is not recommended for failed pyeloplasty in that group of patients, owing to the low success rate.

Inpatient interventions that may preclude outpatient open pyeloplasty in infants

ABSTRACT Objective: In the majority of published series, children undergoing open pyeloplasty are admitted for at least one night. We hypothesized that it would be possible in the majority of infants to perform open pyeloplasty as an outpatient procedure. Materials and Methods: All patients who underwent open pyeloplasty by a single surgeon between 2008 and 2016 were retrospectively reviewed. Demographic data (age at surgery, gender, pre- and postoperative imaging studies, laterality, type of local anesthesia), operative time, duration of hospital stay, need for narcotic analgesics, complications, readmission within 1-month after surgery and need for additional procedures were abstracted. Results: A total of 18 infants underwent open pyeloplasty by single surgeon. Mean age at time of surgery was 19 months (range 3-23 months). There were 8 girls and 10 boys. In addition to general anesthesia, all of the patients received regional anesthesia (caudal block 8, epidural block 8, subcutaneous nerve block 2). Median operative time was 135 minutes (range 81-166). Median hospital stay was 1 day (range 1 to 2). Two patients required iv narcotics for pain management. None of the patients required parenteral administration of other medications during the short hospitalization. No patients required any additional procedures or hospital readmissions within 1 month from surgery. Conclusions: In appropriately selected patients, outpatient pyeloplasty appears to be feasible with an oral postoperative analgesia plan to be administered at home.

A very easy technique of stenting for laparoscopic pyeloplasty: penbegul intravenous cannula (PICA) technique

ABSTRACT Introduction: Double-J stent insertion during laparoscopic pyeloplasty is a difficult and time-consuming process and several techniques were defined to perform a double-J stent with an antegrade approach. In this study we present the technique (PICA) of antegrade double-J placement during laparoscopic pyeloplasty by using 14 gauge intravenous cannula. Surgıcal technıque: After we complete the suturing of the posterior wall of the anastomosis during laparoscopic pyeloplasty, we first puncture the abdominal wall with a 14-gauge "intravenous cannula" from a location that provides most suitable angle for inserting the double-J stent into the ureter. We remove the metal needle of the cannula, and the sheath which has an inner diameter of 5.2F remains over the abdominal wall. The double J stent is then advanced from inside the cannula sheath to the intraperitoneal area; under laparoscopic imaging the stent is gently grasped at its distal end using an atraumatic laparoscopic forceps to insert it into the ureter. The stent is then pulled down to its proximal end, and after the guidewire is removed, the proximal end of the double-J stent is placed inside the renal pelvis with an atraumatic forceps. With this technique we can apply the double-J stent in just one step. Additionaly we can use a 14-gauge IV cannula sheath as a trocar when needed during laparoscopic pyeloplasty to retract an organ or reveal an anastomosis line. Comments: Our new technique of antegrade double-J placement during laparoscopic pyeloplasty by 14 gauge intravenous cannula sheath, is very easy and quick to perform.

Bilateral compartment syndrome of the lower limbs after urological surgery in the lithotomy position: a clinical case / Síndrome compartimental dos membros inferiores após cirurgia urológica na posição de litotomia: um relato de caso

Acute compartment syndrome of the lower extremities after urological surgery in the lithotomy position is a rare but potentially devastating clinical and medicolegal problem. We report the case of a 67-year-old male who underwent laparoscopic prostatectomy surgery to treat cancer, spending 180 minutes in surgery. Postoperatively, the patient developed acute compartment syndrome of both legs, needing emergency bilateral four-compartment fasciotomies, with repeated returns to the operating room for second-look procedures. The patient also exhibited delayed wound closure. He regained full function within 6 months, returning to unimpaired baseline activity levels. This report aims to highlight the importance of preoperative awareness of this severe complication which, in conjunction with early recognition and immediate surgical management, may mitigate long-term adverse sequelae and improve postoperative outcomes

A síndrome compartimental aguda dos membros inferiores após cirurgia urológica na posição de litotomia é um problema clínico e médico-legal raro, mas potencialmente devastador. Reportamos o caso de um homem de 67 anos submetido a uma prostatectomia laparoscópica por câncer. A cirurgia durou 180 min. No pós-operatório, o paciente desenvolveu síndrome compartimental aguda de ambos os membros inferiores, necessitando de fasciotomias de urgência, com retornos repetidos à sala de cirurgia para procedimentos adicionais. O paciente também apresentou fechamento tardio da ferida. Ele recuperou a função completa dentro de 6 meses e retornou a um nível de atividade basal irrestrito. Este artigo tem a importância de ressaltar a consciência pré-operatória desta grave complicação que, em conjunto com o reconhecimento precoce e o tratamento cirúrgico imediato, pode mitigar sequelas adversas em longo prazo e melhorar os resultados pós-operatórios

Surgical treatment for stress urinary incontinence in women: A systematic review and meta-analysis / Tratamento cirúrgico da incontinência urinária de esforço em mulheres: revisão sistemática e metanálise

Abstract Objective To compare surgical treatments for stress urinary incontinence in terms of efficiency and complications. Data Sources We searched the MEDLINE and COCHRANE databases using the terms stress urinary incontinence, surgical treatment for stress urinary incontinence and sling. Selection of Studies Forty-eight studies were selected, which amounted to a total of 6,881 patients with scores equal to or higher than 3 in the Jadad scale. Data Collection Each study was read by one of the authors, added to a standardized table and checked by a second author. We extracted data on intervention details, follow-up time, the results of treatment and adverse events. Data Synthesis Comparing retropubic versus transobturator slings, the former was superior for both objective (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.05-1.54) and subjective (OR, 1.23; 95% CI, 1.02-1.48) cures. Between minislings versus other slings, there was a difference favoring other slings for subjective cure (OR, 0.58; 95% CI, 0.39- 0.86). Between pubovaginal sling versus Burch surgery, there was a difference for both objective (OR, 2.04; 95% CI, 1.50-2.77) and subjective (OR, 1.64; 95% CI, 1.10-2.44) cures, favoring pubovaginal sling. Therewas no difference in the groups: midurethral slings versus Burch, pubovaginal sling versus midurethral slings, transobturator slings, minislings versus other slings (objective cure). Retropubic and pubovaginal slings are more retentionist. Retropubic slings have more bladder perforation, and transobturator slings, more leg and groin pain, neurological lesion and vaginal perforation. Conclusion Pubovaginal slings are superior to Burch colposuspension surgery but exhibit more retention. Retropubic slings are superior to transobturator slings, with more adverse events. Other slings are superior to minislings in the subjective aspect. There was no difference in the comparisons between midurethral slings versus Burch colposuspension surgery, pubovaginal versus midurethral slings, and inside-out versus outside-in transobturator slings.

Costs analysis of surgical treatment of stress urinary incontinence in a brazilian public hospital, comparing Burch and synthetic sling techniques

ABSTRACT Introduction Surgical treatment of urinary incontinence progressed significantly with the introduction of synthetic slings. However, in some public Brazilian hospitals, the costs of these materials prevent their routine use. Objective To compare the costs of ambulatory synthetic sling surgery with an historical series of patients submitted to Burch surgery in a Brazilian public hospital. Materials and Methods Twenty nine incontinent patients were selected to synthetic sling surgery. Demographic data were prospectively collected and also the costs of the procedure, including drugs and materials, use of surgical and recovery wards, medical staff and hospitalization. These data were compared to the costs of 29 Burch surgeries performed before the introduction of synthetic slings. Results Demographic data were similar, although median age was lower in the group submitted to Burch surgery (46.3±8.6 versus 56.2±11.3 (p<0.001)). Cost was significantly lower in patients submitted to sling in all items, except for time spent in recovery ward. Total value of 29 Burch surgeries was R$ 217.766.12, and of R$ 68.049.92 of 29 patients submitted to sling surgery (p<0.001). Conclusion Burch surgery was more expensive than ambulatory synthetic transobturator sling surgery, even when the cost of the synthetic sling was considered.

Can baseline serum creatinine and e-GFR predict renal function outcome after augmentation cystoplasty in children?

ABSTRACT Objective To assess cut-off value of creatinine and glomerular filtration rate for augmentation cystoplasty (AC) in paediatric age-group. Materials and Methods Data of all paediatric-patients (<18 years) with small capacity bladder, in whom AC was advised between 2005-2015 were reviewed. All patients were divided in two-groups, AC-group and control-group (without AC). Creatinine and e-GFR were assessed at the time of surgery, at 6 months and at last follow-up. Renal function deterioration was defined as increase in creatinine by ≥25% from baseline value or new-onset stage-3 CKD or worsening of CKD stage with pre-operative-CKD stage-3. ROCs were plotted using creatinine and e-GFR for AC. Results A total of 94 patients with mean-age 8.9 years were included. The mean creatinine and e-GFR were 1.33mg/dL and 57.68mL/min respectively. Out of 94 patients, AC was performed in 45 patients and in the remaining 49 patients AC was not done (control-group), as they were not willing for the same. Baseline patient's characteristics were comparable in both Groups. 22 underwent gastro-cystoplasty (GC) and 25 underwent ileo-cystoplasty (IC). Decline in renal function was observed in 15 (33.3%) patients of AC-group and in 31 (63.3%) patients of control-group. Patients having creatinine ≥1.54mg/dL (P=0.004, sensitivity (S) 63.6% and specificity (s) 90.5%) at baseline and e-GFR ≤46mL/min (P=0.000, S=100% and s=85.7%) at the time of surgery had significantly increased probability of renal function deterioration on follow-up after AC. Conclusion e-GFR ≤46mL/min and creatinine ≥1.54mg/dL at time of surgery could serve as a predictor of renal function deterioration in AC in paediatric patients.

Surgical management of urinary tract stones in children:experience from Tikuranbessa hospital, Addis ababa, Ethiopia

Introduction: Urinary stone disease is a disorder with significant impact on quality of life. Moreover, children have a higher recurrence rate owing to associated metabolic and anatomic abnormalities. Management has changed with technological advances. Despite the current trend, open stone surgery is still widely practiced in developing countries. However, there have been no reports regarding treatment of this disease in children from Ethiopia so far. We aimed to determine the mode of management and outcomes of the différent approches for childhood urolithiasis which practiced in our institution. We also tried to assess factors leading to adverse outcomes.Methods: This is a retrospective descriptive study of pediatric patients who underwent surgical procedures for urolithias from September 2010 to August 2015. Medical records were reviewed for factors thought to affect outcome of management.Results: We investigated 50 children aged 0-15 years and the mean age for operation was 8.5 ± 3.2 years. The stones were found exclusively in upper urinary tract in 56%, lower urinary tract in 30% and a combination of sites in 14%. All lower urinary tract stones were managed with open surgery, of which cystolithotomy comprised 81%. Common procedures performed for upper urinary tract stones were open stone surgery (41 %) and ureteroscopic intervention in (34.5%). Success rate with ureteroscopy was 30%. Post-operative complications occurred in 24%; common ones being urinary tract infection (10%) and urinary leak (10%). The factors with significant correlation to post-operative complications were history of urinary tract infection and chronic kidney disease (p=0.02 and p=0.047 respectively). Recurrence occurred in 12%. Thirty percent of the children required a second surgical procedure.Conclusion: The practice in our institution is still evolving towards the standard approaches of stone treatment. Metabolic evaluation is lacking, post-operative complications are high and our experience with pediatric ureteroscopy was not satisfactory. Most of these issues were associated with our socioeconomic status, as facility was not adequately equipped and patients presented late with renal failure

Transition to adulthood with a bladder augmentation: histopathologic concerns

ABSTRACT Aim: To investigate the histopathologic changes in native bladder and gastrointestinal segment, the relation between histopathologic changes, type of operation and the period passed over operation in patients with bladder augmentation. Materials and methods: Twenty consecutive patients were enrolled in this study. Histopathologic evaluation of the cystoscopic mucosal biopsies from native bladder and enteric augment was performed in all patients. Results: Active or chronic non-specific inflammation of various degrees was found in all specimens except two. Metaplastic changes were detected in 3 patients. Two patients had squamous metaplasia (one focal, one extensive) and one patient had intestinal metaplasia. All metaplastic changes were found in native bladder specimens. The type of augmentation in patients with metaplastic changes were ileocystoplasty and sigmoidocystoplasty. No signs of malignancy were detected in any patient. Conclusion: The complexity of the disorders requiring bladder augmentation does not let the surgeons to draw a clear line between different groups of complications including malignancy formation. However, due to challenging course of the augmentation procedure itself, surgeons should be well aware of the possibility of malignancy development.

¿Existen diferencias entre la vía transobturadora y retropúbica en la resolución de la incontinencia de orina de esfuerzo? / Are there differences between transobturator and retropubic sling in the resolution of stress urinary incontinence?

PROPÓSITO: Comparar la eficacia y complicaciones de la vía retropúbica (TVT o RP) y la vía transobturadora (TVT-O) en el tratamiento quirúrgico de la incontinencia de orina de esfuerzo (IOE). MÉTODOS: Estudio retrospectivo de pacientes con diagnóstico de IOE operadas entre Julio 2004 y Julio 2014 en el Hospital Clínico de la Universidad de Chile. Se evaluaron los datos demográficos, antecedentes médicos, síntomas y examen físico tanto preoperatorio como post operatorio y seguimiento post quirúrgico. RESULTADOS: De un total de 715, se analizaron los datos de 383 pacientes operada durante la fecha. 59,7% (n= 229) fueron sometidas a TVT-O y 40,3% (n=154) a TVT. Un 4,8% (n=11) de las pacientes en que se realizó cinta transobturadora tenían antecedente de cirugía previa de incontinencia versus un 14,29% (n=22) de las pacientes en que se realizó cinta retropúbica (P 0,006). Los datos post operatorios fueron ajustados según el dato anterior. En el seguimiento post operatorio se presentaron diferencias significativas en la disfunción del vaciamiento vesical [OR 0,28, (95%IC 0,10-0,74), p = 0,011]; y en el dolor inguinal post operatorio [OR 0,19 (95%IC 0,06-0,56), p = 0,003); siendo ambos más frecuentes en el grupo transobturador. No hubo diferencias significativas en el éxito subjetivo de la resolución de la IOE así como en otro tipo de complicaciones postoperatorias. CONCLUSIONES: Si bien ambas técnicas presentan tasas similares de éxito subjetivo en la resolución de la IOE, en nuestra experiencia, la vía transobturadora presenta mayor riesgo de disfunción del vaciamiento vesical y dolor inguinal postoperatorio.

PURPOSE: To compare the efficacy and complications of the retropubic sling (TVT or RP) and the transobturator sling (TVT-O or TOT) for the surgical treatment of stress urinary incontinence (SUI). METHODS: Retrospective study including patients diagnosed with SUI who had surgery between July 2004 and July 2014 at the Clinical Hospital of the University of Chile. Demographics, medical history, symptoms and physical examination (preoperative, postoperative and post-surgical follow-up) were evaluated. RESULTS: From a total of 715 operated during this period, the data from 383 patients was analyzed. 59.7% (n = 229) were submitted to TVT-O and 40.3% (n = 154) to TVT. 4.8% (n = 11) of patients in the transobturator sling group had previously had an incontinence surgery versus 14.29% (n = 22) of patients that had a retropubic sling (P 0.006). The postoperative data was adjusted according to this data. At the postoperative follow-up there were significant differences in bladder emptying dysfunction [OR 0.28 (95% CI 0.10 to 0.74), p = 0.011]; and postoperative groin pain [OR 0.19 (95% CI 0.06 to 0.56), p = 0.003); both being more frequent in the transobturator group. There were no significant differences in subjective success of the resolution of the SUI as well as other postoperative complications. CONCLUSIONS: Although both techniques have similar rates of subjective success in solving the SUI, in our experience, the transobturator approach has increased risk of bladder emptying dysfunction and postoperative groin pain.

Unilateral extravesical ureteral reimplantation via inguinal incision for the correction of vesicoureteral reflux: a 10-year experience

ABSTRACT Introduction and Objective: Multiple options exist for the surgical management of vesicoureteral reflux (VUR). We report on our 10-year experience using the inguinal approach to extravesical ureteral reimplantation (EVR). Materials and Methods: Patient characteristics of age, gender, and reflux grade were obtained and outcomes of operative time, hospital stay, and radiographic resolution were assessed. Results: 71 girls and 20 boys with a mean age of 74 months (range 14-164) underwent inguinal EVR via a 3.5-cm inguinal mini-incision. Mean follow up was 10.9 months (range 0.4-69.7). Average grade of reflux was 2.80. Average operative time was 91 minutes (range 51-268). The procedure was successful in 87 of 91 patients (95.6%). The 3 cases of reflux that persisted were all grade 1 and managed expectantly. Contralateral reflux developed in 9 cases, all of which resolved after treatment with either Deflux or ureteral reimplant. There were 4 case of urinary retention that resolved after a brief period of CIC or indwelling catheterization. There were no cases of ureteral obstruction. Most patients were discharged on post-operative day 1 (85/91) and no hospitalization extended beyond 3 days. Conclusions: The inguinal approach to extravesical ureteral reimplantation should be considered as a potentially minimally invasive alternative to endoscopic and robotic treatment of VUR with a success rate more comparable to traditional open approaches. We feel it is the method of choice in cases of unilateral VUR requiring surgical correction.
