Mini Endoscopic Combined Intra-Renal Surgery (MiniECIRS) with endoview puncture in A 12 month boy. A safe but challenging procedure.

INTRODUCTION: Associating minipercutaneous nephrolithotomy and retrograde flexible ureteroscopy (fURS) is called Mini Endoscopic Combined Intra-Renal Surgery (miniECIRS). It's a safe and efficient technique, also in children. MATERIAL AND METHODS: The video describes miniECIRS in a 12 month-old boy with an infectious pelvic left stone (16 mm) and multiple caliceal stones. The UAS used was a 10FR and the percutaneous access was a 14Fr with Clear-Petra® sheath. RESULTS: The operative time was 180 min and blood losses were virtually absent. There were no intra- or post-operative complications and the patient was discharged at the 5th day. After 1 month, double J was removed having a stone free status. CONCLUSIONS: MiniECIRS with endoview puncture is a safe and efficient technique when performed by experienced hands. Therefore, it is an alternative to consider for the treatment of complex lithiasis in the pediatric population.

The Utility and Safety of Ureteral Access Sheath During Retrograde Intrarenal Surgery in Children.

OBJECTIVE: To compare retrograde intrarenal surgery (RIRS) with and without ureteral access sheath (UAS) in different pediatric age groups. METHODS: The data of RIRS for kidney stone in children were obtained from 9 institutions. Demographic characteristics of patients and stones, intraoperative and postoperative results were recorded. While analyzing the data, patients who underwent RIRS without UAS (group 1) (n = 195) and RIRS with UAS (group 2) (n = 194) were compared. RESULTS: Group 1 was found to be young, thin, and short (P <.001, P = .021, P <.001), but there was no gender difference and similar symptoms were present except hematuria, which was predominant in group 2 (10.6% vs 17.3%, P <.001). Group 1 had smaller stone diameter (9.91 ± 4.46 vs 11.59 ± 4.85 mm, P = .001), shorter operation time (P = .040), less stenting (35.7% vs 72.7%, P = .003). Re-intervention rates and stone-free rates (SFR) were similar between groups (P = .5 and P = .374). However, group 1 had significantly high re-RIRS (P = .009). SFR had a positive correlation with smaller stone size and thulium fiber laser usage compared to holmium fiber laser (HFL) (P <.001 and P = .020), but multivariate analysis revealed only large stone size as a risk factor for residual fragments (P = .001). CONCLUSION: RIRS can be performed safely in children with and without UAS. In children of smaller size or younger age (<5 years), limited use of UAS was observed. UAS may be of greater utility in stones larger than 1 cm, regardless of the age, and using smaller diameter UAS and ureteroscopes can decrease the complications.

Mobility and Sporting Activity After Renal Trauma: A Survey Regarding Best Clinical Practice During the Recovery Stage.

OBJECTIVE: To evaluate strategies that are followed after pediatric renal trauma during the recovery stage, with an emphasis on mobility and involvement in subsequent sporting activities. Renal trauma is the most common urogenital trauma in children. The American Association for the Surgery of Trauma (AAST) scale is most commonly used to stratify the severity of injury. There is no consensus in the existing literature with respect to the recovery stage following renal trauma. METHODS: A survey was constructed by the European Association of Urology (EAU) - Young Academic Urologists (YAU) Pediatric Urology Working Group and then made digitally available on SurveyMonkey. The survey consists of 15 questions exploring relevant factors and timing to start again with mobility and activity. RESULTS: In total 153 people responded, of whom 107 completed the entire survey. The presence of pain and severity of trauma were acknowledged as most important factors to commence mobilization, whereas presence of hematuria was identified as an additional factor for sporting activity. Regardless of severity of trauma a minimum of 90% of respondents recommend return to noncontact sports within 12weeks. For contact sports, a minimum of 33% of respondents advised >12weeks minimum before starting again. A small number of respondents would never allow sporting activities again. CONCLUSION: The time to allow sporting activity shows high variation among the respondents, some even restricting sporting activities completely. This survey highlights the need for a standardized protocol based on multicenter follow-up data.

Comparison of Low-Power vs High-Power Holmium Lasers in Pediatric Retrograde Intrarenal Surgery Outcomes.

Objectives: To compare the outcomes of using low-power (up to 30 W) vs high-power (up to 120 W) holmium lasers in retrograde intrarenal surgery (RIRS) in children and to analyze if lasering techniques and the use of access sheath have any influence on the outcomes. Methods: We retrospectively reviewed data from 9 centers of children who underwent RIRS with holmium laser for the treatment of kidney stones between January 2015 and December 2020. Patients were divided into two groups: high-power and low-power holmium laser. Clinical, perioperative variables and complications were analyzed. Outcomes were compared between groups using Student's t-test for continuous variables, and Chi-square and Fisher's exact test for categorical variables. A multivariable logistic regression analysis model was also performed. Results: A total of 314 patients were included. A high-power and low-power holmium laser was used in 97 and 217 patients, respectively. Clinical and demographic variables were comparable between both groups, except for stone size where the low-power group treated larger stones (mean 11.11 vs 9.70 mm, p = 0.018). In the high-power laser group, a reduction in surgical time was found (mean 64.29 vs 75.27 minutes, p = 0.018) with a significantly higher stone-free rate (SFR) (mean 81.4% vs 59%, p < 0.001). We found no statistical differences in complication rates. The multivariate logistic regression model showed lower SFR in the low-power holmium group, especially with larger (p = 0.011) and multiple stones (p < 0.001). Conclusion: Our real-world pediatric multicenter study favors high-power holmium laser and establishes its safety and efficacy in children.

Retrograde Intrarenal Surgery in Children: Evolution, Current Status, and Future Trends.

Introduction: Incidence of urolithiasis in children has increased in recent years and with technological advancements and miniaturization of surgical instruments, pediatric urologists have acquired an impressive arsenal for their treatment. Retrograde intrarenal surgery (RIRS) has gained widespread popularity as it is a natural extension of semirigid ureteroscopy and can be done through natural orifice minimizing the morbidity of percutaneous access. The aim of this narrative review is to describe how RIRS has evolved over the decades in children and if the age-related anatomical difference impacts reported outcomes especially stone-free rate (SFR) and complications. Materials and Methods: An electronic literature search from inception to October 15, 2021 was performed using Medical Subject Heading terms in several combinations on PubMed, EMBASE, and Web of Science without language restrictions. A total of 2022 articles were founded and 165 articles were full-text screening. Finally, 2 pediatric urologists included 51 articles that summarize the available literature regarding the development and use of RIRS in children. Results: RIRS as of today is well established as a superior modality for all stones in all locations compared with extracorporeal shockwave lithotripsy both in children and adults. The passive dilation has decreased the need of active ureteral dilation, but the need to perform prestenting is not defined yet. Regarding the use of the ureteral access sheath, the literature tends to lean toward its placement in most cases, but we do not know its long-term effects over the growth of children. Finally, the SFR has increased as the experience of pediatric urologists increases, as well as the number of complications has decreased. Conclusion: RIRS in pediatrics has crossed many milestones, yet many areas need further research and larger data are required to make RIRS the procedure of choice for renal stone management in children across all age groups.

Retrorenal colon in pediatric patients with urolithiasis: Is the supine position for PCNL advantageous?

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is one of the main approaches for the treatment of large and complex stones in pediatric patients. The patient position for PCNL has been classically divided into prone or supine and the prone position is more commonly used. One of the most feared complications of this surgical technique is colon injury and the objective of this work is to evaluate the incidence of retrorenal colon (RRC) both supine and prone position, in pediatric patients, through radiological images. MATERIALS AND METHOD: A retrosepctive review was performed of all abdominal CT scans performed in one center, in patients under 18 years since 2017 to 2019. The ideal path for percutaneous puncture was traced in the upper, middle, and lower calyces of both kidneys in the prone and supine positions and contact with the kidney and adjacent organs was evaluated, with a uro-radiologist. Chi-square test and Student's t test were applied. RESULTS: 50 CT-scans were performed on 44 children. Patients had a mean age of 12.6 years and 71.4% were male. Twenty-five scans were performed in the prone and 25 in the supine position. The incidence of RRC for the left kidney (LK) was significantly higher in the lower calyx in prone position than in the supine position, 28% vs 4% (p = 0.049), and the right kidney (RK) presented RRC only in the prone position. The liver was the most frequent retrorenal organ (97.7%) for the RK, with a non-significant difference by position, while for the LK the spleen was the most frequent (61.1%). DISCUSSION: Colon injury is one of the most morbid complication in PCNL and one of the reasons to perform a CT scan before surgery, on which its incidence appears to be <1% in adults. The present study revealed RRC to be present in three (12%) patients in the supine position and seven (28%) patients in the prone position (p=0.15). These results were slightly higher from those reported in adults (supine: 1.7%-10%; prone: 6.8%-20%), but there are no reports in the literature on this issue to allow appropriate comparison. This is the first study to attempt to assess the incidence of RRC in children according to position. CONCLUSION: The incidence of RRC for an ideal puncture was significantly higher in the lower calyx of the left kidney in the prone position than in the supine position, and in the right kidney, the RRC only occurred in the prone position.

Robotic retroperitoneal lymphadenectomy in paratesticular rhabdomyosarcoma.

INTRODUCTION: Paratesticular sarcoma is an aggressive malignant tumor of mesenchymal origin. The rhabdomyosarcoma is the most common among children. Rhabdomyosarcoma treatment consists of surgery, chemotherapy and radiotherapy. Prognosic depends on local recurrence and distant metastasis. MATERIAL AND METHODS: We present the case of a 16-year-old male, who in April 2016 underwent right radical orchiectomy surgery by testicular mass rapidly evolving, with pathological results indicating a paratesticular rhabdomyosarcoma. The extension study showed a precaval adenopathy suggestive of lymph node metastasis, therefore it was a high-grade rhabdomyosarcoma. There was an appropriate response after chemotherapy (Protocol EpSSG RMS2005) and we decided to perform a robotic lymphadenectomy. RESULTS: We performed a transperitoneal approach with 8 mm trocar and 12 mm optica trocar. We accessed the retroperitoneal space through a latero-colic incision. Then we performed a craniocaudal lymph node dissection until the aortic bifurcation. The surgical time was 240 min with a blood loss of 200 ml. There were no complications. The patient was discharged on the fourth day after surgery. Pathology showed metastasis of rhabdomyosarcoma without capsular rupture. After two months, we placed the left testicle into inguinal canal prior to radiotherapy. CONCLUSIONS: Robotic lymph node metastasis lymphadenectomy from paratesticular sarcomas is a feasible treatment with the advantage of minimally invasive surgery and acceptable morbidity.

Semi-closed-circuit vacuum-assisted mini percutaneous nephrolithotomy in the pediatric population: the initial experience of two tertiary referral centers.

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is the gold-standard for complex renal stones treatment in the pediatric population. While the miniaturization of PCNL reduces the risk of bleeding, it can hinder surgical and functional outcomes. The aim of the study was to assess the safety and feasibility of semi-closed-circuit vacuum-assisted Mini-PCNL (vmPCNL) in pediatric patients. METHODS: From January 2017 to December 2018, we prospectively collected data on consecutive vmPCNLs from two European tertiary referral centers. The procedure was performed with the ClearPetra® (Well Lead Medical Co., Ltd., Guangzhou, China) access sheath equipped with a lateral arm connected to the aspiration system (pressure setting ~120-150 cmH2O) by a 200 Ml plastic stone collector. Pre-, intra- and postoperative data and costs were analyzed. The stone-free rate (SFR) was defined as absence of residual fragments >4 mm with either ultrasound or kidney, ureter, and bladder X-ray. RESULTS: Eighteen vmPCNLs were performed in 16 renal units of 13 children. The median age was 119 months (IQR: 97-160) and the weight was 29 Kg (IQR: 25-40). The median cumulative stone size was 32 mm (22-46) with 8 (44.4%) cases of staghorn stones. The OT was 128 min (IQR: 99-167). The basketing was unnecessary in 6/18 (33%) cases. Neither intra-operative complications nor blood transfusions occurred. Postoperative fever was observed in 5/18 (27.8%) cases; in one case a double J ureteral stent was placed for concomitant hydronephrosis. The SFR was 81.3% (13/16), rising to 93.8% (15/16) after ancillary procedures. The materials costs of a vmPCNL (734.8 €) were comparable to mini-PCNL using a reusable set (710.7 €). CONCLUSIONS: The vmPCNL seems to be sustainable, safe and feasible for kidney stones treatment in the pediatric population.

Ultra-mini Pcnl with clear Petra® suction-evacuation access sheath and warming irrigation fluid system (Rocamed®) for stone treatment in children.

INTRODUCTION: Inadvertent perioperative hypothermia (a drop in core temperature to below 36 °C) occurs because of interference with normal temperature regulation by anaesthetic drugs, skin exposure for prolonged periods and the introduction of large volumes of intravenous and irrigation fluids. If the temperature of these fluids is below core body temperature, they can cause significant heat loss. Warming irrigation fluids might prevent some of this heat loss and subsequent hypothermia and that is the role of warming irrigation fluid systems. MATERIAL AND METHODS: The video describes prone ultra mini PCNL with suction-evacuation access sheath under warming irrigation fluid system in a 15 month-old boy with a 2 cm-600HU staghorn calculi and one stone of 7 mm-500HU in proximal ureter. RESULTS: The surgery was performed without intraoperative complications and perioperative hypothermia was prevented. The patient started the surgery at 35.4 °C and the final temperature was 36.3 °C in 90 min of procedure, in addition to being free of stones. CONCLUSIONS: The warming irrigation fluid system can be helpful in preventing inadvertent perioperative hypothermia in children, improving the safety of ultra mini PCNL with suction-evacuation access sheath and shows promising results with high stone-free rates and low complications.

Sexuality of Female Spina Bifida Patients: Predictors of a Satisfactory Sexual Function.

OBJECTIVE: To assess the sexual function of women with spina bifida (SB), and to verify the factors that influence their sexual function. METHODS: A cross-sectional study in which a validated female-specific questionnaire was applied to 140 SB female patients from four different cities (Porto Alegre, Brazil; and Barcelona, Madrid, and Málaga, Spain) between 2019 and 2020. The questionnaires collected data on the clinical characteristics of SB, and female sexual function was assessed using the 6-item version of the Female Sexual Function Index (FSFI-6) validated to Portuguese and Spanish. RESULTS: Half of the patients had had sexual activity at least once in the life, but most (57.1%) did not use any contraception method. Sexual dysfunction was present in most (84.3%) patients, and all sexual function domains were impaired compared those of non-neurogenic women. The presence of urinary and fecal incontinence significantly affected the quality of their sexual activity based on the FSFI-6. CONCLUSION: The specific clinical aspects of the SB patients, such as urinary and fecal incontinence, should be properly addressed by their doctors, since they are associated with reduced sexual activity and lower FSFI-6 scores in the overall or specific domains. There is also a need to improve gynecological care among sexually-active SB patients, since most do not use any contraceptive methods and are at risk of inadvertent pregnancy.

OBJETIVO: Analisar a função sexual de pacientes do sexo feminino com espinha bífida (EB), e avaliar quais fatores influenciam na função sexual. MéTODOS: Uma pesquisa transversal em que um questionário validado para mulheres foi aplicado em 140 pacientes com EB de quatro cidades diferentes (Porto Alegre, Brasil; e Barcelona, Madri e Málaga, Espanha) entre 2019 e 2020. Os questionários coletaram dados sobre características clínicas da espinha bífida, e a função sexual feminina foi avaliada com a versão de seis itens do Índice de Funcionamento Sexual Feminino (IFSF-6) nas versões validadas para português e espanhol. RESULTADOS: Metade das pacientes havia praticado atividade sexual pelo menos uma vez na vida, mas a maioria (57.1%) não utilizava nenhum método contraceptivo. A disfunção sexual estava presente na maioria das pacientes (84.3%), sendo todos os domínios de função sexual prejudicados em comparação com os de mulheres não neurogênicas. A presença de incontinência urinária e fecal afetou significativamente a qualidade da atividade sexual das pacientes. CONCLUSãO: Aspectos clínicos específicos da EB, como incontinência urinária e fecal, devem ser adequadamente abordados pelos médicos assistentes, visto que estão associados à redução na atividade sexual e piores resultados no IFSF-6. Também é necessário melhorar o atendimento ginecológico das pacientes sexualmente ativas, uma vez que a maioria não utiliza métodos contraceptivos e corre o risco de gravidez inadvertida.

Pregnancy in Pateints With Exstrophy-Epispadias Complex: Are Higher Rates of Complications and Spontaneous Abortion Inevitable?

OBJECTIVE: To report on the characteristics of pregnancy in female patients with EEC (exstrophy-epispadias complex), determining in particular whether they are at higher risk of spontaneous abortion or complications. MATERIALS AND METHOD: Fifty patients diagnosed with EEC and treated in a reference center for this pathology were reviewed. Those with an incomplete medical history were excluded, leaving a total of 37 women with a median follow-up of 26 years (1-48 years). The outcome measurements were successful pregnancies, miscarriages, urological, gynecological and obstetric complications, impaired renal function, newborn characteristics, and postpartum urogynecological complications. Descriptive statistics was used. RESULTS: Eight patients achieved 17 pregnancies (88.2% spontaneous). Of these pregnancies, 10 (58.8%) were successful, while 7 (41.2%) terminated in miscarriages. Urinary tract infection (UTI) was the most frequent complication (41.6%) and intestinal occlusion was the most severe. A total of 62.5% of the patients presented genital prolapses after pregnancies. A total of 85.7% of patients were dry during the follow-up after their pregnancies. No newborn presented EEC or any other type of malformation. Our study has the limitation of being a retrospective review of a very heterogeneous and small group of patients. CONCLUSION: EEC patients can achieve spontaneous pregnancies but have an increased risk of miscarriage. For this reason, monitoring and control by a specialized and integrated multidisciplinary team is required to minimize complications.

The impact of neurogenic bladder bowel dysfunction in the sexuality of female spina bifida patients.

INTRODUCTION: The sexual life of Spina Bifida (SB) women may be affected by their physical impairments. Data has consistently associated symptoms such as urinary and fecal incontinence with negative effects on social and intimate life. OBJECTIVE: To analyze the female spina bifida patient sexual life and assess which factors - including bladder bowel dysfunction and bladder augmentation - influenced in the sexual function of patients in a multi-center cross-sectional study. STUDY DESIGN: A cross-sectional survey with validated female-specific questionnaire was applied in 140 spina bifida female patients from four different cities (Porto Alegre/Brazil; Barcelona, Madrid and Málaga/Spain) between 2019 and 2020. Questionnaires collected data on spina bifida clinical characteristics and sexuality, which was assessed using the 6-item version of the Female Sexual Function Index (FSFI-6) in the Portuguese and Spanish validated versions. Female sexual dysfunction was defined as a FSFI-6 total score ≤19. RESULTS: Sexual dysfunction was present in most (84.3%) patients with a median overall FSFI-6 total score of 14.5 (range 4-26), being all sex domains impaired. Bladder augmentation, type of spina bifida, spinal cord level, hydrocephalus, use of wheelchair and psychological disorder were not statistically associated with differences among rates of sexual activity or female sexual dysfunction. The presence of urinary incontinence (UI) showed both significant lower sexual intercourse and higher dysfunction rates (Summary Table). Urinary and fecal incontinence were significantly associated with worst scores in all domains, except for pain. DISCUSSION: Urinary incontinence status was the most relevant factor since it impaired either female sexual dysfunction and sexual activity rates, as well as the FSFI-6 overall and specific domains. These findings are consistent with previous studies who also observed that desire, arousal and lubrication domains had negative effects from urinary loss on SB patients. Fecal incontinence status did not influenced in sexual activity of female sexual dysfunction rates, nevertheless it promoted lower scores in the overall and specific sexual domains. CONCLUSION: Spina bifida is a complex condition that demands proper care to achieve a satisfactory sexual life, specially regarding neurogenic bladder and bowel dysfunction. Clinical aspects in the SB patient, such as urinary and fecal incontinence, should be properly addressed by pediatric urologists since they are associated with female sexual dysfunction and reduced sexual activity, as well as lower FSFI-6 scores in the overall and specific domains. There is also a need to improve communication about sexuality, because only 18.6% of the patients considered it that had received sufficient sex information from physicians.

Assessment of sexual life in spina bifida patients: A survey among pediatric urologists.

OBJECTIVE: To assess the status of the sexual education approach with spina bifida (SB) patients. MATERIALS AND METHODS: An online survey was sent to 223 pediatric urologists from Latin countries, all contacted using email or mobile messaging software. There were 12 questions about participants' demographic characteristics and SB-specific care topics. Data was collected from January 2019 to January 2020. Checklist for reporting results of internet e-survey (CHERRIES) guidelines were followed to ensure the quality of this study. RESULTS: We received 101 valid answers from participants practicing in seven different countries. Among these, 98.4% confirmed that sexuality in the SB population is considered relevant, nevertheless it is only evaluated by 62.5%. Transitional urologists discuss sexuality more often than those whose practice consists solely of pediatric patients (70% vs. 50%). Basic surgeon training (urologist vs. pediatric surgeon), age, part or full-time pediatric urology practice and country of participants were of no statistically different influence inrates of approach to sexuality. CONCLUSION: Our study demonstrates that pediatric urologists are insufficiently addressing sexuality in SB patients. Those who practise transitional urology show higher rates of approach to sexuality with SB patients, which suggests this is an important model of care.

Autologous fat grafting with stem cell transplantation in an exstrophic patient. A case.

INTRODUCTION: Lipofilling has been used in plastic surgery for breast reconstruction and treatment of burns. Carrying out minimally invasive techniques would allow treatment of hypertrophic scars and depressed suprapubic area in exstrophic patients to improve their aesthetic appearance. MATERIAL AND METHODS: This video presents the case of a female 16 year old patient with bladder exstrophy, who initially had an urinary reconstruction with ureterosigmoidostomy and posteriorly bladder augmentation and Mitrofanoff, with hypertrophic scars and depressed abdominal wall in suprapubic area. We present this procedure for autologous fat grafting with stem cells in the abdominal area. RESULTS: The lipofilling procedure was carried out successfully, without intraoperative complications in 120 min. The liposuction was 250 cc and 80 cc was used for injection, achieving the improvement of the aesthetic appearance of the scars in a short time. The imaging control was follow up with abdominal wall ultrasound, three months later, increasing its thickness by 42%. CONCLUSION: The autologous fat grafting with stem cells is a safe and feasible procedure in the exstrophic population, with excellent aesthetic results, but we need long term follow ups to determine how long the effect of fat grafting remains.

[High risk pregnancy in patients with extrophy-epispadia complex: Uro-gynecological characteristics and management.] / Embarazo de alto riesgo en pacientes con complejo extrofia-epispadias: características uro-ginecológicas y manejo.

OBJECTIVE: The exstrophy-epispadias complex (EEC) ranges from distal epispadias to cloacal exstrophy, with serious repercussions on the quality of life of patients. However, reconstructive surgery offers the opportunity to reach adulthood and consider motherhood.The objective of this work is to assess the uro-gynecological characteristics and the risks that pregnant women have with EEC. MATERIALS AND METHOD: Retrospective study of 50 patients diagnosed with EEC and treated in a reference center for this pathology, born between 1968 and 2000. Their medical records were reviewed and all demographic, pathological and gynecological data were collected. RESULTS: 37 patients have the inclusion criteria and of these 8 achieved 17 pregnancies (90% spontaneous and 10% through IVF). 10 were successful (50% at term) and 7 were abortions, 87.5% of which were in the first trimester. Urinary tract infection (UTI) was the most frequent complication (41.6%) and the most severe was intestinal occlusion. None of the patients presented renal function impairment during the gestation or dilation of the pathological upper urinary tract (UUT). 62.5% of the patients presented genital prolapses after pregnancies, 80% of which were grade III and IV. 87.5% were dry in the follow-up after their pregnancies. CONCLUSION: Pregnancy in the EEC patients is high risk and it is crucial that the follow-up is carried out by a specialized and integrated multidisciplinary team to minimize complications.

OBJETIVO: El complejo extrofia-epispadias (CEE) abarca desde las epispadias distales hasta la extrofia de cloaca, con serias repercusiones en la calidad de vida de los pacientes; sin embargo, la cirugía reconstructiva ofrece la oportunidad de llegar a la edad adulta y plantearse la maternidad. El objetivo de este trabajo es valorar las características uro-ginecológicas y los riesgos que presentan las gestantes con CEE. MATERIALES Y MÉTODO: Estudio retrospectivo de 50 pacientes diagnosticadas de CEE y tratadas en un centro de referencia para esta patología, nacidas entre 1968 y 2000. Se revisaron sus historias clínicas y se recogieron todos los datos demográficos, patológicos  y ginecológicos. RESULTADOS: 37 pacientes cumplían los criterios de inclusión y de estas 8 lograron 17 embarazos (90% espontáneos y 10% mediante FIV). 10 fueron exitosos (50% a término) y 7 fueron abortos, 87,5% de los cuales fueron en el primer trimestre. La infección urinaria (ITU) fue la complicación más frecuente (41,6%) y la más severa fue la oclusión intestinal. Ninguna de las pacientes presentó deterioro de la función renal durante la gestación o dilatación del tracto urinario superior (TUS) patológica. 62,5% de las pacientes presentaron prolapsos genitales posteriores a los embarazos, 80% de los cuales fueron grado III y IV. 87,5% se encontraban secas en el seguimiento posterior a sus embarazos. CONCLUSIÓN: El embarazo en el CEE es de alto riesgo y es crucial que el seguimiento sea llevado a cabo por un equipo multidisciplinar especializado e integrado para minimizar las complicaciones.

Determinant factors for chronic kidney disease after partial nephrectomy.

The objective of this review is to evaluate the factors that determine the development or deterioration of Chronic Kidney Disease (CKD) after partial nephrectomy (PN). When current literature is reviewed, it is found that factors that influence renal function after partial nephrectomy, are multifactorial. Those are divided into pre-surgical factors, such as hypertension, diabetes mellitus, urolithiasis, obesity, metabolic syndrome among others; intra-surgical factors, like the surgical technique used, the remaining healthy tissue, the experience of the surgeon, the time and type of ischemia among others. Lastly, post-surgical factors, also impose some influence on the post-surgical renal performance. It was also found that minimally invasive surgery, in addition to its known advantages, seems to offer a greater field of action in the future that will allow more nephrons preservation in any future surgical scenario. Finally, the current trend is to perform PN on all patients, in whom surgery is technically feasible regardless of the approach used, without risking oncological outcomes, patient safety, and without being exposed to any additional complications.

Primary non-Hodgkin lymphoma of the prostate: a case report.

This report is of a 68-year-old male patient with a three-year history of severe, progressive, low urinary tract symptoms (LUTS) with a score of 20 points on the International Symptom Scale. The patient received alpha-1-blocker therapy without adequate response. Transurethral resection of the prostate was performed, and the anatomopathological report indicated the presence of a haematolymphoid small-cell neoplasia and glandulostromal prostatic hyperplasia. Posterior immunohistochemistry evaluation reported an extra-nodal marginal zone-B lymphoma non-Hodgkin lymphoma. The patient was followed up for five years by the urology and oncology departments. In the fourth year of follow-up, the patient had B symptoms (fever, night sweats and weight loss). At the same time, laboratory tests showed haemolytic anaemia; then a new bone marrow biopsy was carried out. The histopathological specimen showed six lymphoid aggregates, constituted by a B-cell population with intra-trabecular predominance and reactivity for CD20 and BCL-2. New thoracic and abdominal computed tomographies were performed without any findings suggestive of extra-prostatic spreading.
