RESUMEN
Kidney transplantation (KT) is the optimal form of renal replacement therapy for patients with end-stage renal diseases. However, this health service is not available to all patients, especially in developing countries. The deceased donor KT programs are mostly absent, and the living donor KT centers are scarce. Single-center studies presenting experiences from developing countries usually report a variety of challenges. This review addresses these challenges and the opposing strategies by reviewing the single-center experiences of developing countries. The financial challenges hamper the infrastructural and material availability, coverage of transplant costs, and qualification of medical personnel. The sociocultural challenges influence organ donation, equity of beneficence, and regular follow-up work. Low interests and motives for transplantation may result from high medicolegal responsibilities in KT practice, intense potential psychosocial burdens, complex qualification protocols, and low productivity or compensation for KT practice. Low medical literacy about KT advantages is prevalent among clinicians, patients, and the public. The inefficient organizational and regulatory oversight is translated into inefficient healthcare systems, absent national KT programs and registries, uncoordinated job descriptions and qualification protocols, uncoordinated on-site investigations with regulatory constraints, and the prevalence of commercial KT practices. These challenges resulted in noticeable differences between KT services in developed and developing countries. The coping strategies can be summarized in two main mechanisms: The first mechanism is maximizing the available resources by increasing the rates of living kidney donation, promoting the expertise of medical personnel, reducing material consumption, and supporting the establishment and maintenance of KT programs. The latter warrants the expansion of the public sector and the elimination of non-ethical KT practices. The second mechanism is recruiting external resources, including financial, experience, and training agreements.
RESUMEN
BACKGROUND: Although the availability of related living donors (LDs) provides a better chance for receiving kidney transplantation (KT), the evaluation protocols for LD selection remain a safeguard for the LD's safety. These protocols are variable from one center to another, resulting in variable rates of decline of the potential LDs (PLDs). The decline of willing PLDs may occur at any stage of evaluation, starting from the initial contact and counseling to the day of operation. AIM: To identify the causes of the decline of PLDs, the predictors of PLD candidacy, and the effect on achieving LDKT. METHODS: A retrospective study was performed on the willing PLDs who attended our outpatient clinic for kidney donation to their related potential recipients between October 2015 and December 2022. The variables influencing their candidacy rate and the fate of their potential recipients were studied. Two groups of PLDs were compared: Candidate PLDs after a completed evaluation vs non-candidate PLDs with a complete or incomplete evaluation. A multivariate logistic regression was performed to assess the factors contributing to the achievement of PLD candidacy. RESULTS: Of 321 willing PLDs, 257 PLDs (80.1%) accessed the evaluation to variable extents for 212 potential recipients, with a mean age (range) of 40.5 ± 10.4 (18-65) years, including 169 females (65.8%). The remaining 64 PLDs (19.9%) did not access the evaluation. Only 58 PLDs (18.1%) succeeded in donating, but 199 PDLs (62.0%) were declined; exclusion occurred in 144 PLDs (56.0%) for immunological causes (37.5%), medical causes (54.9%), combined causes (9.7%), and financial causes (2.1%). Regression and release occurred in 55 PLDs (17.1%). The potential recipients with candidate PLDs were not significantly different from those with non-candidate PLDs, except in age (P = 0.041), rates of completed evaluation, and exclusion of PLDs (P < 0.001). There were no factors that independently influenced the rate of PLD candidacy. Most patients who failed to have KT after the decline of their PLDs remained on hemodialysis for 6 mo to 6 years. CONCLUSION: The rate of decline of willing related PLDs was high due to medical or immunological contraindications, release, or regression of PLDs. It reduced the chances of high percentages of potential recipients in LDKT.
RESUMEN
BACKGROUND: Preemptive living donor kidney transplantation (PLDKT) is recommended as the optimal treatment for end-stage renal disease. AIM: To assess the rate of PLDKT among patients who accessed KT in our center and review the status of PLDKT in Egypt. METHODS: We performed a retrospective review of the patients who accessed KT in our center from November 2015 to November 2022. In addition, the PLDKT status in Egypt was reviewed relative to the literature. RESULTS: Of the 304 patients who accessed KT, 32 patients (10.5%) had preemptive access to KT (PAKT). The means of age and estimated glomerular filtration rate were 31.7 ± 13 years and 12.8 ± 3.5 mL/min/1.73 m2, respectively. Fifty-nine patients had KT, including 3 PLDKTs only (5.1% of total KTs and 9.4% of PAKT). Twenty-nine patients (90.6%) failed to receive PLDKT due to donor unavailability (25%), exclusion (28.6%), regression from donation (3.6%), and patient regression on starting dialysis (39.3%). In multivariate analysis, known primary kidney disease (P = 0.002), patient age (P = 0.031) and sex (P = 0.001) were independent predictors of achievement of KT in our center. However, PAKT was not significantly (P = 0.065) associated with the achievement of KT. Review of the literature revealed lower rates of PLDKT in Egypt than those in the literature. CONCLUSION: Patient age, sex, and primary kidney disease are independent predictors of achieving living donor KT. Despite its non-significant effect, PAKT may enhance the low rates of PLDKT. The main causes of non-achievement of PLDKT were patient regression on starting regular dialysis and donor unavailability or exclusion.
RESUMEN
BACKGROUND: Despite the documented effects of the coronavirus disease 2019 (COVID-19) on spermatogenesis, the reversibility of these effects is uncertain. We aimed to assess the changes of sperm quality between the infection and recovery phases of COVID-19 in reproductive-aged men. The semen quality of men with mild-to-moderated COVID-19 (defined by the degrees of symptoms and chest involvement on computed tomography) was studied during October, 2020-May, 2021 at our hospital. Two semen samples were analyzed at timings estimated to represent spermatogenic cycles during the infection and recovery phases of COVID-19. RESULTS: A total of 100 patients were included with mean ± SD (range) age of 24.6 ± 3.3 (21-35) years. During infection, 33% of patients had abnormal semen quality. However, a significant reduction was found in this abnormality from 33 to 11% (P < 0.001) after recovery from infection. In a comparison of the two semen analyses, there were significant improvements in the mean values of sperm progressive motility (P =0.043) and normal morphology (P < 0.001). However, the mean sperm concentration showed a statistically insignificant increase (P = 0.844). CONCLUSIONS: In reproductive-aged patients with mild-to-moderate COVID-19, the effects on seminal quality were recoverable, represented by significant improvements in the means of progressive sperm motility and normal morphology between the infection and recovery phases of COVID-19. TRIAL REGISTRATION: ClinicalTrials, NCT04595240 .
RéSUMé: CONTEXTE: Malgré les effets documentés de la maladie à coronavirus 2019 (COVID-19) sur la spermatogenèse, la réversibilité de ces effets reste incertaine. Notre objectif était d'évaluer les changements de la qualité du sperme entre les phases d'infection et de récupération de la COVID-19 chez des hommes en âge de procréer. La qualité du sperme d'hommes atteints d'une forme de COVID-19 de légère à modérée (définie par les degrés de symptômes et l'atteinte thoracique lors de la tomodensitométrie) a été étudiée entre octobre 2020 et mai 2021 dans notre hôpital. Deux échantillons de sperme ont été analysés à des moments estimés représenter les cycles de spermatogénèse pendant les phases d'infection et de rétablissement de la COVID-19. RéSULTATS: Au total, 100 patients ont été inclus avec un âge moyen ± ET (intervalle) de 24,6 ± 3,3 ans (21-35). Au cours de l'infection, 33% des patients avaient une qualité anormale de sperme. Une réduction significative de cette anomalie de 33 à 11% (p < 0,001) a toutefois été observée après la guérison de l'infection. La comparaison des deux analyses de sperme montre des améliorations significatives des valeurs moyennes de la motilité progressive (p = 0,043) et de la morphologie normale (p< 0,001) des spermatozoïdes. Cependant, la concentration moyenne de spermatozoïdes a montré une augmentation statistiquement non significative (p = 0,844). CONCLUSIONS: Chez les patients en âge de procréer atteints d'une forme de COVID-19 légère à modérée, les effets sur la qualité spermatique étaient récupérables, avec des améliorations significatives des valeurs moyennes de la motilité progressive et de la morphologie normale des spermatozoïdes entre les phases d'infection et de récupération de la COVID-19.
RESUMEN
BACKGROUND: The increasing kidney retransplantation rate has created a parallel field of research, including the risk factors and outcomes of this advanced form of renal replacement therapy. The presentation of experiences from different kidney transplantation centers may help enrich the literature on kidney retransplantation, as a specific topic in the field of kidney transplantation. AIM: To identify the risk factors affecting primary graft function and graft survival rates after second kidney transplantation (SKT). METHODS: The records of SKT cases performed between January 1977 and December 2014 at a European tertiary-level kidney transplantation center were retrospectively reviewed and analyzed. Beside the descriptive characteristics, the survivals of patients and both the first and second grafts were described using Kaplan-Meier curves. In addition, Kaplan-Meier analyses were also used to estimate the survival probabilities at 1, 3, 5, and 10 post-operative years, as well as at the longest follow-up duration available. Moreover, bivariate associations between various predictors and the categorical outcomes were assessed, using the suitable biostatistical tests, according to the predictor type. RESULTS: Out of 1861 cases of kidney transplantation, only 48 cases with SKT were eligible for studying, including 33 men and 15 women with a mean age of 42.1 ± 13 years. The primary non-function (PNF) graft occurred in five patients (10.4%). In bivariate analyses, a high body mass index (P = 0.009) and first graft loss due to acute rejection (P = 0.025) were the only significant predictors of PNF graft. The second graft survival was reduced by delayed graft function in the first (P = 0.008) and second (P < 0.001) grafts. However, the effect of acute rejection within the first year after the first transplant did not reach the threshold of significance (P = 0.053). The mean follow-up period was 59.8 ± 48.6 mo. Censored graft/patient survival rates at 1, 3, 5 and 10 years were 90.5%/97.9%, 79.9%/95.6%, 73.7%/91.9%, and 51.6%/83.0%, respectively. CONCLUSION: Non-immediate recovery modes of the first and second graft functions were significantly associated with unfavorable second graft survival rates. Patient and graft survival rates of SKT were similar to those of the first kidney transplantation.
RESUMEN
The simultaneous kidney transplantation and ipsilateral native nephrectomy for autosomal dominant polycystic kidney disease does not seem to be associated with increased rates of comorbidity and complications. This outcome can efficiently be achieved when the indication and surgical approach of native nephrectomy are properly justified.
RESUMEN
OBJECTIVE: The aim of this study is to compare the outcomes of right- and left-sided live donor nephrectomies using the inverted kidney transplantation technique for right live donor nephrectomy on transplantation. MATERIAL AND METHODS: A retrospective review was done for the cases of live donor nephrectomy, either as open donor nephrectomy or laparoscopic donor nephrectomy between 2004 and 2019. Inverted kidney transplantation was used with right-sided grafts. The variables of the right- and left-sided live donor nephrectomies were compared. RESULTS: There were 202 live donor nephrectomies including 71 (35.1%) open donor nephrectomies and 131 (64.9%) laparoscopic donor nephrectomies with 4 cases of conversion to open donor nephrectomy. There were 119 (58.9%) right-sided and 83 (41.1%) left-sided live donor nephrectomies with insignificantly different mean operative time (123 and 127 minutes; P=.09), mean warm ischemia time (82.3 and 84.5 seconds; P=.32), and mean blood loss (73 and 78 mL; P=.18), respectively. Inverted kidney transplantation was performed for 86% of grafts from right live donor nephrectomies. Discharge from hospital was on an average of 4.3 days postoperatively. There were only 3 complications (1 in right live donor nephrectomy and 2 in left live donor nephrectomies) with grade 2 according to Clavien-Dindo Classification. Incidence of delayed graft function (P=.09), transplant vein thrombosis (1 case in each group), 1-year graft survival rate (93.2% vs. 94.8%; P=.12), and 1-year serum creatinine levels (1.4 ± 0.3 vs. 1.3 ± 0.2; P=.09) revealed statistically insignificant differences. CONCLUSION: Regardless of the surgical technique, the right live donor nephrectomy seems to be technically as safe as the left live donor nephrectomy for both the donors and the recipients. Using inverted kidney transplantation provided convenient extensions of graft's vessels to full length with no significant increased incidence of vascular thrombosis.
RESUMEN
PURPOSE: To identify the predictors of nadir serum creatinine (SCr) after drainage of bilaterally obstructed kidneys (BOKs) by different modes: double-J stent (JJ) versus percutaneous nephrostomy (PCN) and unilateral versus bilateral drainage. METHODS: A prospective non-randomized study was performed on patients with BOKs and raised SCr during December 2019-November 2021. Relevant variables were studied for improvement and non-improvement and for benign and malignant underlying obstructions (BUO and MUO). RESULTS: This study included 107 patients with BOKs including 68 (63.6%) males and 39 (36.4%) females. After drainage, 86 (80.4%) patients get improved, while 21 (19.6%) patients failed to reach a nadir SCr. Drainage by PCN was significantly higher in MUO, while JJ was significantly higher in BUO (p < 0.001). Also, bilateral drainage was a significant predictor of improvement in MUO (p = 0.03). In contrast, mode of drainage had no significant effect on improvement in BUO (p = 0.84), but bilateral drainage was a significant factor of rapid time to nadir (p = 0.02). Univariate analyses revealed no significant effects on the improvement in SCr from the studied variables, except the male gender (p = 0.01), old age (p < 0.001), MUO (p = 0.01), unilateral drainage (p < 0.001), and use of PCN for drainage (p < 0.001). By multivariate analysis, unilateral drainage (p = 0.01) and MUO (p < 0.001) were independent predictors of non-improvement in patients with BOKs. CONCLUSIONS: Male gender, old age, MUO, unilateral drainage, and drainage by PCN were significant predictors of non-improvement in SCr after drainage of BOKs. However, unilateral drainage and MUO were the only independent predictors of non-improvement.

BACKGROUND: Unilateral small-sized kidney is a radiological term referring to both the congenital and acquired causes of reduced kidney volume. However, the hypoplastic kidney may have peculiar clinical and radiological characterizations. AIM: To evaluate the clinical presentations, complications, and management approaches of the radiologically diagnosed unilateral hypoplastic kidney. METHODS: A retrospective review of the records of patients with a radiological diagnosis of unilateral hypoplastic kidney between July 2015 and June 2020 was done at Assiut Urology and Nephrology Hospital, Assiut University, Egypt. RESULTS: A total of 33 cases were diagnosed to have unilateral hypoplastic kidney with a mean (range) age of 39.5 ± 11.2 (19-73) years. The main clinical presentation was loin pain (51.5%), stone passer (9.1%), anuria (12.1%), accidental discovery (15.2%), or manifestations of urinary tract infections (12.1%). Computed tomography was the most useful tool for radiological diagnosis. However, radioisotope scanning could be requested for verification of surgical interventions and nephrectomy decisions. Urolithiasis occurred in 23 (69.7%) cases and pyuria was detected in 22 (66.7%) cases where the infection was documented by culture and sensitivity test in 19 cases. While the non-complicated cases were managed by assurance only (12.1%), nephrectomy (15.2%) was performed for persistent complications. However, symptomatic (27.3%) and endoscopic (45.6%) approaches were used for the management of correctable complications. CONCLUSION: Unilateral hypoplastic kidney in adults has various complications that range from urinary tract infections to death from septicemia. Diagnosis is mainly radiological and management is usually conservative or minimally invasive.
RESUMEN
PURPOSE: Robot-assisted kidney transplant (RAKT) recently proved to provide functional results similar to the preferred open kidney transplant (OKT), but with inferior wound morbidity. In a comparative prospective study, we explored the systemic inflammatory response syndrome (SIRS) after KT and compared OKT with RAKT. METHODS: Forty-nine patients underwent pre-emptive ABO-compatible kidney transplantations (KT) between January 2017 and December 2018 in 2 centers: 25 RAKT, 24 OKT. Postoperative SIRS was biologically assessed by serum markers (NGAL, CRP and IL-6) measured at: T0 (preoperative/baseline), T1(H1), T2(H6), T3(H12), T4(H24), T5(D2), T6(D3) and T7(D5) after KT. RESULTS: Inflammatory markers + eGFR were assessed in OKT vs. RAKT. IL-6 peak value occurred at H6 and reached ×9 from baseline. CRP peak occurred at H24 and reached ×28 from baseline (All P < 0.05). NGAL decreased after surgery with a plateau (divided by 2 from baseline) from H12 to D5. There was no significant difference in IL-6, CRP and NGAL kinetics and peak values between RAKT and OKT (All P > 0.05). Serum creatinine and eGFR on postoperative days 1, 3 and 7 were similar in RAKT and OKT (All P > 0.05). Delayed graft function was not observed. CONCLUSION: In this exploratory study, the biological evaluation of postoperative SIRS after living-donor kidney transplant revealed no significant difference between OKT and RAKT and similar functional outcomes in the short term. These results highlight the safety of RAKT as an alternative to OKT in this setting.

PURPOSE: The main objective was to compare minor (Clavien I-II) and major (Clavien ≥ III) intra- and postoperative complications of living donor robotic assisted kidney transplantation (RAKT) in obese (≥ 30 kg/m2 BMI), overweight (< 30/ ≥ 25 kg/m2 BMI) and non-overweight recipients (< 25 kg/m2 BMI). METHODS: For the present retrospective study, we reviewed the multi-institutional ERUS-RAKT database to select consecutive living donor RAKT recipients. Functional outcomes, intra- and postoperative complications were compared between obese, overweight and non-overweight recipients. RESULTS: 169 living donor RAKTs were performed, by 10 surgeons, from July 2015 to September 2018 in the 8 European centers. 32 (18.9%) recipients were obese, 66 (39.1%) were overweight and 71 (42.0%) were non-overweight. Mean follow-up was 1.2 years. There were no major intra-operative complications in either study group. Conversion to open surgery occurred in 1 obese recipient, in 2 overweight recipients and no conversion occurred in non-overweight recipients (p = 0.3). Minor and major postoperative complications rates were similar in the 3 groups. At one-year of follow-up, median eGFR was similar in all groups [54 (45-60) versus 57 (46-70) versus 63 (49-78) ml/min/1.73 m2 in obese, overweight and non-overweight recipient groups, respectively, p = 0.5]. Delayed graft function rate was similar in the 3 groups. Only the number of arteries was an independent predictive factor of suboptimal renal function at post-operative day 30 in the multivariate analysis. CONCLUSION: RAKT in obese recipients is safe, compared to non-overweight recipients and yields very good function, when it performed at high-volume referral centers by highly trained transplant teams.

Renal disorders are associated with Hepatitis E virus (HEV) infection. Progression to end-stage renal disease and acute kidney injury are complications associated with HEV infection. The mechanisms by which HEV mediates the glomerular diseases remain unclear. CD10+/CD13+ primary proximal tubular (PT) epithelial cells, isolated from healthy donors, were infected with HEV. Inflammatory markers and kidney injury markers were assessed in the presence or absence of peripheral blood mononuclear cells (PBMCs) isolated from the same donors. HEV replicated efficiently in the PT cells as shown by the increase in HEV load over time and the expression of capsid Ag. In the absence of PBMCs, HEV was not nephrotoxic, with no direct effect on the transcription of chemokines (Cxcl-9, Cxcl-10, and Cxcl-11) nor the kidney injury markers (kidney injury molecule 1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and interleukin 18 (lL-18)). While higher inflammatory responses, upregulation of chemokines and kidney injury markers expression, and signs of nephrotoxicity were recorded in HEV-infected PT cells cocultured with PBMCs. Interestingly, a significantly higher level of IFN-γ was released in the PBMCs-PT coculture compared to PT alone during HEV infection. In conclusion: The crosstalk between immune cells and renal epithelium and the signal axes IFN-γ/chemokines and IL-18 could be the immune-mediated mechanisms of HEV-induced renal disorder.
RESUMEN
OBJECTIVES: To present our center's experience in the management of adrenal myelolipoma in the context of shifting from the open to the laparoscopic adrenalectomy approach. MATERIALS AND METHODS: A retrospective search of our center's records was done for reported cases of adrenal myelolipoma during the period July 2001-June 2016. All the cases with histopathologically-documented adrenal myelolipoma diagnosis were included. Relevant demographic and clinical variables were studied with a comparison between the open and laparoscopic approaches. RESULTS: Of more than 82,000 urological surgeries, 238 adrenalectomies were done with only 22 cases of myelolipoma that had a mean age and body mass index of 52.4 ± 10.3 years and 30.23 kg/m2, respectively. The main clinical presentation was accidental discovery. The largest dimension of tumors varied from 6 to 16 cm. Computed tomography described a characteristic picture of hypodense heterogeneous adrenal tumors in all cases, while magnetic resonance imaging was indicated for malignancy suspicion in only 5 cases. Adrenal tumor markers were normal in all cases. Open and transperitoneal laparoscopic adrenalectomies were used in 14 and 8 cases, respectively. The latter approach was insignificantly advantageous in the need for blood transfusion, postoperative pain degree, need for analgesia, and hospital stay duration (p = 0.22). Histo-pathological examination revealed benign adipose tissue and myeloid cells and confirmed the diagnosis of adrenal myelolipoma in all cases. CONCLUSIONS: Adrenal myelolipoma is a rare non-functioning benign tumor. Laparoscopic excision seems to be a promising alternative approach to the traditional open adrenalectomy, even in the context of large tumors and obesity.
RESUMEN
BACKGROUND: We report on our multicentre evaluation of the occurrence and management of complications with the ATOMS device (A.M.I., Austria). PATIENTS AND METHODS: Between 10/09 and 09/18, a total of 187 patients with persistent postoperative stress urinary incontinence received an ATOMS device in Madrid (n = 101) or Halle (n = 86). This prospective evaluation was carried out consecutively. In addition to complications, patient age, BMI, comorbidities and previous treatments for prostate cancer and urinary incontinence were examined. Statistical analysis was performed with GraphPad Prism 7® (GraphPad Software, Inc., La Jolla, USA); p < 0.05 was considered significant. RESULTS: The average age of the overall population was 69.4 years, with a mean CCI of 4.3. In total, 18.2% of the patients had diabetes mellitus, 21.9% were irradiated, and 14.1% and 22.9% underwent previous surgery for urinary incontinence and urethral stricture, respectively. The overall success rate of the device was 80.2%. A total of 51 postoperative complications (51/187, 27.3%) were observed, with 18 grade I (9.6%), 1 grade II (0.5%), 3 grade IIIa (1.6%) and 29 grade IIIb (15.5%) complications. The most serious postoperative complications were primary wound infection (8/187, 4.3%) and long-term cutaneous erosion with subsequent infection (15/187, 8.02%). The main risk factors for complications were previous radiotherapy (p = 0.003) and surgery for urethral stricture (p = 0.017). No other parameters were significant in bivariate analysis (p > 0.05). CONCLUSION: The most severe complications of ATOMS implantation were primary wound infection and cutaneous erosion, especially in the presence of previous radiotherapy. Particular focus on performing hygienic and accurate implantation techniques is recommended.

PURPOSE: First robotic-assisted kidney transplants (RAKT) were performed in Germany in 2016. To introduce and establish this method as a routine procedure for patients in transplantation medicine, our 2-year experiences are presented. METHODS: Non-randomized open-label cohort study to compare functional and operative results as well as complication rates between RAKT and standard open transplantation. Collected data are part of ERUS RAKT Group Registry. RESULTS: Since initiation of the RAKT program 21/27 transplantations after living kidney donations have been performed as RAKT. This represents the largest series of RAKT in Germany. Patient survival, transplant survival, and primary function rate are 100% (mean follow-up 12.9 ± 8.6 month). Mean incision to closure time was 306.1 ± 45.5, mean handling time 70.8 ± 13.1 min compared to 212.1 ± 40.6 min and 51.7 ± 9.9 min, respectively, in the standard group. Despite extended operating times using the robotic approach, comparable complication rates and graft function with significant reduction in median length of hospital stay (14 vs. 20 days) were observed. CONCLUSIONS: RAKT extends the options for recipients towards minimally invasive techniques. Compared to classic open surgery, RAKT appears to be safe in selected patients without influencing graft outcome or higher complication rates. However, RAKT till today is not suitable for all patients but seems to be one of the upcoming new standard techniques in kidney transplantation.

BACKGROUND: We report the multicentre comparison of the different port types of the adjustable transobturator male incontinence system (ATOMS, A.M.I., Austria). METHODS: Between 10/09 and 10/16, 383 patients received an ATOMS. Of these, 63% received the inguinal port (IP, 2009-2013), 23% the intraoperative manually connectable scrotal port (SP, 2013-2015), and 14% the pre-connected fully silicone-covered scrotal port (SSP, 2014-2016). During the follow-up period, continence parameters, pain and quality of life ratings and postoperative port-associated complications were evaluated and compared. Statistical analysis was performed with GraphPad Prism 7®, p < 0.05 considered as significant. RESULTS: Regarding preoperative parameters (BMI, ASA score, previous radiotherapy/incontinence surgery, and preoperative 24-h pad count/24-h pad test), no significant differences were found. Regarding perioperative parameters, the mean operative time was significantly shorter for the SP and SSP (IP vs. SP p < 0.0001, IP vs. SSP p = 0.0048, SP vs. SSP p = 0.697). Comparison of the postoperative 24-h pad count, 24-h pad test and uroflowmetry data revealed no significant differences. However, the postoperative ICIQ-SF score was significantly better for the SSP (p = 0.0232) than the SP. A significant difference was also observed in postoperative port-associated complications. According to the Clavien-Dindo classification, we identified one grade I and 29 grade IIIb complications for the IP, 1 grade I and 6 grade IIIb complications for the SP, but only 2 grade IIIb complications for the SSP (IP vs. SP p = 0.0231, IP vs. SSP p = 0.0189 and SP vs. SSP p = 0.0453). CONCLUSION: The SSP shows fewer complications while retaining comparable efficacy.

Background: The urinary incontinence system ATOMS (A.M.I., Austria) generates suburethral compression through its sphincter cushion. To what extent the ATOMS may lead to overactive bladder (OAB) symptoms or which risk factors for these symptoms exist remain unknown to date. We report on our multicentre evaluation on the prevalence, status, and therapy of OAB after ATOMS. Methods: Between 10/09 and 01/17, a total of 361 patients received an ATOMS device in Vienna and Halle. A prerequisite for surgery was persistent male stress urinary incontinence lasting at least 6 months after the primary intervention, as well as the failure of conservative treatment. Patients with a preoperative untreated anastomotic stricture or detrusor overactivity were excluded. In addition to continence and voiding parameters, patient's age, BMI, comorbidities, and pre-treatment strategies of the underlying disease and urinary incontinence were examined. If de novo OAB was present, urodynamics were used for further clarification. Statistical analysis was performed with GraphPad Prism 7® (GraphPad Software, Inc., La Jolla, USA), p < 0.05 considered significant. Results: OAB presented 18 patients (4.9%). Regarding the degree of urinary incontinence as well as uroflowmetry, residual volume and comorbidities, patients with an OAB showed no differences compared to patients without an OAB (p < 0.05). Only previous radiotherapy or urinary incontinence surgery and urethral stricture interventions resulted in statistically significant differences based on the bivariate analysis (p = 0.030, p = 0.006, p = 0.007). The consecutive postoperative urodynamics revealed a sensory OAB in 17 patients and a low-compliance bladder in a patient with newly diagnosed insulin-dependent type II diabetes mellitus. OAB was treated with a standard dose of antimuscarinic drugs and for the low-compliance bladder with botulinum toxin type A. Conclusion: OAB symptoms can occur after ATOMS implantation, but are rare and have no clear correlation to the incontinence device but rather are due to urinary incontinence-related underlying diseases and previous treatments.
RESUMEN
INTRODUCTION: To prospectively compare the perioperative and functional outcomes of laparoscopic (LP) and open pyeloplasty (OP) in three academic institutions. MATERIAL AND METHODS: Between September 2012 and September 2016, 102 patients with primary uteropelvic junction obstruction (UPJO) underwent pyeloplasty (51 LP and OP for the other 51 patients). Demographic data, perioperative parameters, including operative time, estimated blood loss, complications, length of hospital stay, and functional outcome were compared, and SF-8 Health Survey scoring was recorded for each group.Patients were followed up by ultrasound (US) and /or intravenous urography (IVU) at 3, 6 and 12 months. A MAG-3 renal scan was performed at 3 months postoperatively. RESULTS: The mean operative time was significantly shorter in the open group (153.2 ±42 min vs. 219.8 ±46 min; P <0.001). Compared to OP, the mean postoperative analgesia (Diclofenac) requirement was significantly less in the LP group (101.1 ±36 mg vs. 459.1 ±123 mg; P <0.001). The median hospital stay was significantly shorter for LP (2.7 ±1.8 days vs. 9.09 ±7.3 days; P <0.001). The median follow-up period was 19.7 months (12-28 months). The success rate was 96.1% in the OP group and 94.1% in the LP group. CONCLUSIONS: In spite of being a technically demanding procedure, LP offers faster recovery and higher patient satisfaction. In our hands, OP still has a shorter operative time and relatively lower retreatment rate.
RESUMEN
Background: Idiopathic overactive bladder (iOAB), with or without urge incontinence (UI), has significant psychosocial effects on patients' quality of life (QoL). The first choice of treatment for iOAB is anticholinergics and, alternatively, the ß-3-adrenoceptor agonist mirabegron. However, systemic side effects and contraindications should be considered for both medications. Objective: We report the efficacy, safety and effects on QoL of botulinum toxin therapy (onabotulinum toxin type A, BOTOX®, Allergan) among patients with iOAB ± UI. Patients and Methods: Between 2005 and 2013, 51 patients were treated with onabotulinum toxin A (100 units). The inclusion criteria were the presence of confirmed iOAB ± UI with previous use of anticholinergic medication. Micturition frequency, pad count, postvoid residual volume and QoL were evaluated using two validated questionnaires [the Client Satisfaction Questionnaire-8 (CSQ-8) and the King's Health Questionnaire (KHQ)]. Statistical analysis was performed with SPSS 24.0 (p < 0.05). Results: After botulinum toxin injection, a significant improvement in iOAB ± UI symptoms was observed. The micturition frequency decreased from 10.4 ± 0.5 to 5.2 ± 0.4 micturitions per day (p = 0.026), and the pad count decreased from 3.6 ± 1.0 to 1.2 ± 0.3 pads per day (p = 0.033). Anticholinergics were not used during the administration of botulinum toxin therapy. Complications and postoperative need for intermittent self-catheterization (ISC) were not observed. Overall, 72 and 24% of patients reported being "satisfied" or "very satisfied" with the treatment. Additionally, 66% of patients would choose botulinum toxin again for the treatment of iOAB. Conclusion: Botulinum toxin therapy is an efficient, safe, and life-improving treatment for iOAB.
RESUMEN
BACKGROUND: Kidney transplantation using grafts with multiple vessels (GMVs) is technically demanding and may be associated with increased risk of complications or suboptimal graft function. To date, no studies have reported on robot-assisted kidney transplantation (RAKT) using GMVs. OBJECTIVE: To report our experience with RAKT using GMVs from living donors, focusing on technical feasibility and early postoperative outcomes. DESIGN, SETTING, AND PARTICIPANTS: We reviewed the multi-institutional, prospectively collected European Association of Urology (EAU) Robotic Urology Section (ERUS)-RAKT database to select consecutive patients undergoing RAKT from living donors using GMVs between July 2015 and January 2018. Patients undergoing RAKT using grafts with single vessels (GSVs) served as controls. In case of GMVs, ex vivo vascular reconstruction techniques were performed during bench surgery according to the case-specific anatomy. INTERVENTION: RAKT with regional hypothermia. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Intraoperative outcomes and early (30 d) postoperative complications and functional results were the main study endpoints. Multivariable logistic regression analysis evaluated potential predictors of suboptimal renal function at 1 mo. RESULTS AND LIMITATIONS: Overall, 148 RAKTs were performed during the study period. Of these, 21/148 (14.2%) used GMVs; in all cases, single arterial and venous anastomoses could be performed after vascular reconstruction. Median anastomoses and rewarming times did not differ significantly between the GMV and GSV groups. Total and cold ischemia times were significantly higher in the GMV cohort (112 vs 88min, p=0.004 and 50 vs 34min, p=0.003, respectively). Overall complication rate and early functional outcomes were similar among the two groups. No major intra- or postoperative complications were recorded in the GMV cohort. At multivariable analysis, use of GMVs was not significantly associated with suboptimal renal function at 1 mo. Small sample size and short follow-up represent the main study limitations. CONCLUSIONS: RAKT using GMVs from living donors is technically feasible and achieved favorable perioperative and short-term functional outcomes. Larger studies with longer follow-up are needed to confirm our findings. PATIENT SUMMARY: In this study, we evaluated for the first time in literature the results of RAKT from living donors using kidneys with multiple arteries and veins. We found that, in experienced centers, RAKT using kidneys with multiple vessels is feasible and achieves optimal results in terms of postoperative kidney function with a low number of postoperative complications.
