Técnica quirúrgica para la corrección simultánea del prolapso de órganos pélvicos y la incontinencia urinaria recidivada mediante laparoscopia / Combined laparoscopic surgery for the treatment of pelvic organ prolapse and recurrent urinary incontinence

INTRODUCCIÓN: La colposacropexia laparoscópica (CL) es el tratamiento gold standard del prolapso de órganos pélvicos (POP) apical. El esfínter urinario artificial (EUA) presenta elevada eficacia en el tratamiento de la incontinencia urinaria de esfuerzo recidivada (IUEr). OBJETIVO: Describir por primera vez la técnica de CL e implante laparoscópico de EUA mediante un abordaje vesicovaginal a la cara posterior del cuello vesical. MATERIAL Y MÉTODOS: La cirugía se realiza por un abordaje transperitoneal. Se crea el espacio rectovaginal y se fija la malla posterior. Se realiza la disección del espacio vesicovaginal con ayuda de una valva vaginal, se crean los espacios laterovesicales y se comunican ambos con el espacio vesicovaginal. Se fija la malla anterior. Se diseca la cara anterior del cuello y se coloca el manguito. Se fijan ambas mallas al promontorio. Se introduce el reservorio, se coloca el botón de activación en el labio mayor y se realizan las conexiones de forma habitual. Finalmente, se cierra el peritoneo. RESULTADOS: El tiempo quirúrgico fue de 180 minutos, la sonda vesical se retiró al quinto día y la estancia fue de cinco días. El EUA se activó a la sexta semana. No hubo complicaciones perioperatorias. Tras 12 meses, la paciente presenta continencia completa y curación objetiva y subjetiva del POP. CONCLUSIONES: La disección vesicovaginal es un paso común en esta técnica de CL y colocación de EUA. La visión directa del cuello vesical permitiría disminuir el riesgo de erosión. Recomendamos esta técnica en casos seleccionados de POP e IUEr

INTRODUCTION: Laparoscopic sacral colpopexy (LSC) is the gold standard treatment for apical pelvic organ prolapse (POP). Artificial urinary sphincter (AUS) has a high success rate in treating recurrent stress urinary incontinence (SUI). OBJECTIVE: To describe the first simultaneous LSC and AUS implantation through a vesicovaginal approach to the bladder neck. MATERIAL AND METHODS: Operation is performed through a transperitoneal approach. The rectovaginal space is created and the posterior mesh is fixed. The vesicovaginal and both laterovesical spaces are dissected. The vesicovaginal space is connected to both lateral spaces. This is main step of the procedure because it let us place the cuff around the bladder neck in a non-blind fashion. The anterior mesh is fixed to the vagina. The anterior side of the bladder neck is dissected and the cuff implanted. Both meshes are fixed to the promontory. Pressure-regulating balloon is inserted, the pump is placed in the labia majora and the components are connected. Peritoneum is closed. RESULTS: Surgical time was 180 minutes, bladder catheter was removed at 5th postoperative day, hospital stay was 5 days. The AUS was activated 6 weeks after surgery. No perioperative complications occurred. After 12 months the patient is pad-free and prolapse was objectively and subjectively cured. CONCLUSIONS: Vesicovaginal dissection is a shared step in this technique of LSC and AUS implantation. This approach could minimize the risk of bladder neck injury. We propose this technique in selected cases of prolapse and recurrent SUI

Sepsis urinaria tras tratamiento endourológico de la litiasis por ureterorrenoscopia / Urinary sepsis after endourological ureterorenoscopy for the treatment of lithiasis

Objetivo: Evaluar la incidencia, presentación clínica y factores asociados al desarrollo de sepsis urinaria tras la realización de una ureterorrenoscopia. Material y métodos: Estudio retrospectivo de los pacientes intervenidos mediante ureterorrenoscopia para el tratamiento de la litiasis entre julio de 2015 y octubre de 2017. Se identificaron aquellos pacientes que desarrollaron sepsis urinaria en los primeros 30 días tras la intervención. Se recogieron antecedentes personales, clínicos, quirúrgicos y microbiológicos. Se realizó análisis estadístico mediante chi2 (o test exacto de Fisher), t de Student (o U de Mann-Whitney) o regresión logística según procediese. Resultados: Se realizaron 246 ureterorrenoscopias, 184 (74,8%) sobre litiasis ureterales y 62 (25,2%) sobre litiasis renales, con una edad media de 52 (44,5-59,5) años. Tras el procedimiento, 18 (7,3%) pacientes desarrollaron sepsis urinaria, 10 de ellos (55,5%) en las primeras 24h. El urocultivo mostró enterobacterias (61,1%) y enterococos (38,9%). El antibiograma mostró mayor sensibilidad a nitrofurantoínas (100%) y a quinolonas (72%). El análisis estadístico mostró que el sexo femenino, el inicio clínico de la litiasis en forma de sepsis urinaria, haber recibido antibiótico o haber precisado derivación urinaria mediante doble J en el inicio, el urocultivo prequirúrgico positivo y la persistencia de restos litiásicos tras la cirugía se asociaron de forma significativa (p<0,05) al desarrollo de sepsis urinaria tras la ureterorrenoscopia. Conclusión: La sepsis urinaria es una complicación que aparece tras la realización de una ureterorrenoscopia, especialmente en pacientes de sexo femenino, con antecedente de sepsis urinaria, antibioterapia, doble J, urocultivo previo positivo o presencia de restos litiásicos tras el procedimiento

Objective: To evaluate the incidence, clinical presentation and factors associated with the development of urinary sepsis after performing ureterorenoscopy. Material and methods: Retrospective study of patients undergoing ureterorenoscopy for the treatment of lithiasis between July 2015 and October 2017. Patients who developed urinary sepsis during the 30 days following the intervention were identified. Personal, clinical, surgical and microbiological backgrounds were collected. Statistical analysis was performed with the Chi squared test (or Fisher's exact test), Student's t (or U Mann-Whitney) or logistic regression as appropriate. Results: 246 ureterorenoscopies were performed, 184 (74.8%) on ureteral stones and 62 (25.2%) on kidney stones, with a mean age of 52 (44.5-59.5) years. After procedure, 18 (7.3%) patients developed urinary sepsis, 10 of them (55.5%) occurred in the first 24h. The urine culture showed enterobacteria (61.1%) and enterococci (38.9%). The antibiogram showed greater sensitivity to nitrofurantoins (100%) and quinolones (72%). The statistical analysis showed that female sex, the clinical debut of urolithiasis as urinary sepsis, having received antibiotic or having required urinary diversion by a double J during debut, positive presurgical uroculture and the persistence of residual lithiasis after surgery were significantly associated (p < 0.05) with the development of urinary sepsis after ureterorenoscopy. Conclusion: Urinary sepsis is a complication that appears after performing ureterorenoscopy, especially in female patients with a history of urinary sepsis, antibiotic therapy, double J, previous positive urine culture or residual lithiasis after the procedure

Comparación entre nefrolitotomía percutánea y ureteroscopia flexible para el tratamiento de litiasis renales de entre 2 y 3 cm / Comparison between percutaneous nephrolithotomy and flexible ureteroscopy for the treatment of 2 and 3cm renal lithiasis

Contexto y objetivos: El tratamiento de primera elección para litiasis > 2 cm es la nefrolitotomía percutánea (NLP), dejando a la ureteroscopia flexible (URS-F) como una segunda opción. En la presente revisión se evaluaron la tasa libre de litiasis y las complicaciones de ambas técnicas en el tratamiento de litiasis de tamaño entre 2 y 3 cm. Material y métodos: Revisión sistemática de estudios que compararon las dos técnicas. Fueron excluidos aquellos estudios que no fueran comparativos, los realizados en población pediátrica o con litiasis menores de 2 cm o mayores de 3 cm. Dos investigadores realizaron independientemente la búsqueda, obteniendo 5 estudios que abarcaban un total de 815 pacientes: 252 pertenecieron al grupo de URS-F y 563 al de NLP. Cuatro fueron retrospectivos y uno fue prospectivo no aleatorizado. Resultados: La tasa libre de litiasis osciló entre el 47,0 y el 95,0% para la URS-F y entre el 87,0 y el 100% para la NLP. La tasa de complicaciones fue del 8,8-29,0% en la URS-F y del 11,9-27,0% en la NLP. La URS-F requirió un número mayor de procedimientos y tuvo un menor descenso de hemoglobina y ascenso de creatinina en comparación con la NLP. Conclusiones: La tasa libre de litiasis fue mayor en la NLP, aunque la URS-F podría alcanzar unos resultados comparables a expensas de realizar varios procedimientos. Ambas técnicas tienen una frecuencia de complicaciones similar, pero con más alteraciones analíticas posquirúrgicas en el grupo de NLP

Context and objectives: The first-line treatment for > 2 cm lithiasis is percutaneous nephrolithotomy (PNL), leaving flexible ureteroscopy (FURS) as a second option. In the present review, the stone-free rate and the complications of both techniques were evaluated in the treatment of 2-3 cm stones. Material and methods: Systematic review of studies that compared both techniques. Studies that were not comparative, as well as those carried out in the paediatric population or with < 2 cm or > 3 cm stones, were excluded. Two researchers independently performed the investigation, obtaining 5 studies that made up a total of 815 patients: 252 belonged to the FURS group and 563 to the PNL group. Four studies were retrospective, and one was non-randomised prospective. Results: Stone-free rate ranged between 47.0% and 95.0% for the FURS and between 87.0% and 100% for the PNL. The complication rate was 8.8-29.0% in the FURS and 11.9-27.0% in the PNL. FURS required a greater number of procedures, and had a lower decrease in haemoglobin and creatinine rise compared to PNL. Conclusions: The stone-free rate was higher for PNL, although the FURS could reach comparable results at the expense of performing several procedures. Both techniques have a similar frequency of complications, but the PNL has more postsurgical analytical alterations

[Angelman's syndrome (happy puppet) in 2 siblings. A follow-up over 10 years]. / Síndrome de Angelman (happy puppet) en dos hermanos. Seguimiento durante diez años.

The Angelman syndrome or "happy puppet" syndrome is a disorder of severe mental retardation, seizure, paroxysms of laughter, absent speech, jerky movements and ataxic gait. We present two sibs, man and woman, with this disorder, fact that support the possible autosomal recessive inheritance as a cause of this pathology, which hereditary mechanism is still a controversial point. Besides, we can observe different expression, being the woman more severely affected than the man. To our knowledge, this is the first mexican family reported with this syndrome, and with a ten years follow up. Chromosomal studies, with high resolution technique, were normal, we did not find the 15 chromosomic deletion referred as a possible cause in some cases, that is why it is undeniable that genetic heterogeneity exists in this syndrome.
