Introducción: La cuarta parte de las mujeres con neoplasias ginecológicas cursa con obstrucción en la vía urinaria, secundaria a infiltración tumoral o compresión extrínseca de los uréteres. La nefrostomía es la alternativa clínica intervencionista para mejorar la nefropatía obstructiva y evitar el tratamiento de diálisis en un paciente oncológico con hidronefrosis. El presente estudio tiene el objetivo de determinar la supervivencia de pacientes con cáncer de cérvix portadoras de nefrostomía. Metodología: El presente estudio observacional se realizó en el Hospital Solón Espinosa Ayala "Solca-Núcleo de Quito" de enero-2014 a diciembre-2018. El cálculo muestral fue no probabilístico, se incluyeron casos de pacientes con cáncer de cérvix con nefrostomía. Las variables fueron: edad, su-pervivencia global, supervivencia con nefrostomía, tipo histológico de la neoplasia de cérvix, estadío, tratamiento oncológico luego de la nefrostomía, complicaciones y repuesta al tratamiento. Para el análisis se usó el método Kaplan Meier. Se analiza supervivencia según estadios funcionales ECOG . Resultados: Se incluyeron 96 casos en el estudio. La media de sobrevida luego de colocar la nefros-tomía fue de 277 días (9.2 meses), y la media de la sobrevida global fue de 462 días (15 meses). Las pacientes con ECOG-0 la supervivencia global fue de 625 días (20.8 meses), con ECOG 1, 2 y 3 fue de 437 días (14.5 meses) P= 0.013. Conclusión: Es este estudio las pacientes con cáncer de cérvix que tienen enfermedad localmente avanzada y metastásica con ECOG 0, son las más beneficiadas del procedimiento de nefrostomía con mejoría de la supervivencia. Las pacientes con enfermedad localmente avanzada y metastásica con ECOG 2 y 3, no mejoraron su sobrevida global con la colocación de nefrostomía, ya que a pesar de que recibieron tratamiento oncológico el 50% de ellas progresaron, pero evitaron el ingreso a programas de diálisis. La principal complicación luego de la colocación del catéter de nefrostomía fue la infección.

Introduction: A quarter of women with gynecological neoplasms present with obstruction in the urinary tract, secondary to tumor infiltration or extrinsic compression of the ureters. Nephrostomy is an interventional clinical alternative to improve obstructive nephropathy and avoid dialysis treatment in a cancer patient with hydronephrosis. The objective of this study was to determine the survival of patients with cervical cancer who underwent nephrostomy. Methodology: The present observational study was carried out at Solón Espinosa Ayala Hospital "Solca-Núcleo de Quito" from January 2014 to December 2018. The sample calculation was nonprobabilistic. Cases of patients with cervical cancer who underwent nephrostomy were included. The variables were age, overall survival, survival with nephrostomy, histological type of cervical neo-plasia, stage, oncological treatment after nephrostomy, complications, and response to treatment. For the analysis, the Kaplan­Meier method was used. Survival was analyzed according to ECOG func-tional stages. Results: Ninety-six cases were included in the study. The median survival after nephrostomy place-ment was 277 days (9.2 months), and the median overall survival was 462 days (15 months). Pa-tients with ECOG-0 had an overall survival of 625 days (20.8 months); those with ECOG 1, 2, and 3 had an overall survival of 437 days (14.5 months) (P= 0.013). Conclusion: In this study, patients with cervical cancer who had locally advanced and metastatic disease with ECOG 0 benefited the most from the nephrostomy procedure with improved survival. Patients with locally advanced and metastatic disease with ECOG scores of 2 and 3 did not improve their overall survival with nephrostomy placement. Fifty percent of them progressed despite receiving cancer treatment, but they avoided admission to dialysis programs. The main complication after placement of the nephrostomy catheter was an infection.

ABSTRACT Purpose: The objective of this study is to evaluate the impact of a previous standard percutaneous nephrolithotomy (PCNL) on the outcomes of retrograde intrarenal surgery (RIRS). Materials and Methods: Outcomes of RIRS performed from January 2017 to January 2020 in adult patients with residual stone fragments ≤20mm after a standard PCNL (Post-PCNL) and symptomatic adult patients with kidney stones ≤20mm (Control) were prospectively studied. Stone-free rate (SFR) was evaluated on a postoperative day 90 non-contrast computed tomography. Surgical complications based on Clavien-Dindo classification during the 90 days of follow-up were recorded. Results: Outcomes of 55 patients and 57 renal units of the post-PCNL group were compared to 92 patients and 115 renal units of the control group. SFR was lower in post-PCNL group than in control (28/57, 49.1% vs. 86/115, 74.8%, p <0.001). Overall complications were more frequent in post-PCNL group (p=0.004). Infundibula strictures were identified and incised with laser in 15/57 (26.3%) renal units of the post-PCNL group. Thirteen renal units had infundibulum stricture at the site of previous percutaneous tract (13/15; 86.7%, p=0.004) and one renal unit had three infundibula strictures. Postoperative complications were not affected by the treatment of infundibula strictures (p=0.198). Conclusions: Previous standard PCNL significantly impairs the outcomes of RIRS. Infundibula strictures can be found in 26.3% of the patients with residual stone fragments after standard PCNL for large burden kidney stones. The main site of infundibulum stricture after standard PCNL is the infundibulum of the entry calyx.

ABSTRACT The presence of lower pole stones poses a unique challenge due to the anatomical considerations involved in their management and treatment. Considerable research has been performed to determine the optimal strategy when faced with this highly relevant clinical scenario. Standard options for management include observation, shock wave lithotripsy, retrograde intrarenal surgery, or percutaneous nephrolithotomy. Indeed, each approach confers a distinct set of risks and benefits, which must be placed into the context of patient preference and expected outcomes. The current state of practice reflects a combination of lessons learned from managing calculi not only in the lower pole, but also from other locations within the kidney as well.

ABSTRACT Purpose: To report a case of successful removal of right staghorn renal calculi in a 3-year-old girl with Arnold-Chiari malformation and multiple urogenital anomalies. Case report: A 3-year-old female child with the diagnosis of Arnold-Chiari type 2 malformation was referred to our clinic due to presence of 9 kidney stones with a total volume of 10743mm3. The total of the longest diameters of all stones was calculated as 11.4cm. The patient had a urogenital septum, bifid bladder, and duplicated collecting system on the right side. An 18F Amplatz sheath was placed and mini-percutaneous nephrolithotomy was performed successfully by laser and pneumatic lithotripter. Any residual urinary tract stones or urinary tract infection were not detected during the 6th-month follow-up. Conclusion: Urolithiasis requires a thorough understanding of the underlying causes, as well as an effective and minimally invasive treatment. It is important for urologists to understand the complexity of the optimal stone management in pediatric patients in order to maximize treatment efficacy and minimize morbidity. We conclude that it is essential to treat urolithiasis in a single session in children with urogenital anomalies and accompanying congenital anomalies who have past surgical history.

OBJECTIVE@#To compare the short-term effects and long-term outcomes of incisional procedure and dilatation procedure to manage diverticular neck in percutaneous nephrolithotomy for diverticular stones.@*METHODS@#Clinical data of 61 patients with diverticular stones who underwent percutaneous nephrolithotomy from June 2009 to January 2019 were retrospectively collected and analyzed, which was as follous: (1) basic information: age, gender, body mass index (BMI), American Society of Anesthesiology (ASA) classifications and preoperative symptoms.(2)stone characteristic and procedure-related data: location and size of stone, skinned renal access length and procedure time.(3)perioperative clinical data: hemoglobin drop, Clavien's classification and stone-free rate. Long-term follow-ups were performed for more than 5 years after the patients were discharged.@*RESULTS@#Fifty-three patients were included based on the inclusion and exclusion criteria, and were divided into the dilation group (n=37) and the incision group (n=16) by the treatment methods of diverticular neck. There were 24 male patients (45.3%) and 29 female patients (54.7%), with a mean age of 39.96±12.88 years. Stones were mainly located in the upper pole (n=32, 60.38%) and posterior area (n=41, 77.4%), with a predominance of single stone (n=36, 67.9%). There was no statistically significant difference in demographic data and stone characteristics between the two groups except for age and stone burden. Forty-five patients (84.9%) reached stone-free status after surgeries, and 44 patients (83.0%) postoperative symptoms improved. Twelve patients were lost to the follow-ups, and 41 cases were followed up for an average of 77 months. One recurrence occurred 1 year after surgery. Fifteen patients underwent operations within the past 5 years and the overall 5-year recurrence rate for the remaining 26 patients was 34.6%. There was no statistically significant difference in the incidence of perioperative complications, postoperative stone-free rate and recurrence rate between the two groups, and the recurrence rate was significantly higher 5 years postoperatively than 1 year postoperatively. The proportion of the patients who remained lithotripsy-free and residual stone status decreased significantly.@*CONCLUSION@#Both incisional and dilatation procedures in percutaneous nephrolithotomy to manage diverticular neck could bring the satisfactory postoperative stone free rate. The recurrence rate was about 30% to 40% 5 years after surgery.

ABSTRACT Patients with staghorn renal stones are challenging cases, requiring careful preoperative evaluation and close follow-up to avoid stone recurrence. In this article we aim to discuss the main topics related to staghorn renal stones with focus on surgical approach. Most of staghorn renal stones are composed of struvite (magnesium ammonium phosphate) and are linked to urinary tract infection by urease-producing pathogens. Preoperative computed tomography scan and careful evaluation of all urine cultures made prior surgery are essential for a well-planning surgical approach and a right antibiotics choice. Gold standard surgical technique is the percutaneous nephrolithotomy (PCNL). In cases of impossible percutaneous renal access, anatrophic nephrolithotomy is an alternative. Shockwave lithotripsy and flexible ureteroscopy are useful tools to treat residual fragments that can be left after treatment of complete staghorn renal stone. PCNL can be performed in supine or prone position according to surgeon's experience. Tranexamic acid can be used to avoid bleeding. To check postoperative stone-free status, computed tomography is the most accurate imaging exam, but ultrasound combined to KUB is an option. Intra-operative high-resolution fluoroscopy and flexible nephroscopy have been described as an alternative for looking at residual fragments and save radiation exposure. The main goals of treatment are stone-free status, infection eradication, and recurrence prevention. Long-term or short-term antibiotic therapy is recommended and regular control imaging exams and urine culture should be done.

SUMMARY INTRODUCTION: Patients with bilateral kidney stones and burdened by large stones are challenging cases for endourologists. Simultaneous bilateral percutaneous nephrolithotomy (sbPCNL) is an option; however, it may be accompanied by important morbidity. An alternative is a staged PCNL, operating one side each time. Herein, we compare the impact of sbPCNL and staged PCNL on complication rates and renal function. METHODS: Patients who underwent sbPCNL or staged bilateral PCNL with a frame time of 6 months were searched in our prospectively collected kidney stone database. Groups were compared for age, gender, body mass index (BMI), comorbidities (classification by the American Society of Anesthesiology - ASA), stone size, Guy's score, stone-free status, renal function, blood loss, blood transfusion rate, complication rate, and length of hospital stay. RESULTS: Twenty-six patients and 52 kidney units were enrolled. The mean operative time was 134.7 min. Only 11.3% of cases had complications, all of them minor (Clavien ≤ 2). Overall, the stone-free rate was 61.50%. Comparing the groups, there was a significantly longer operative time in the sbPCNL group (172.5 vs. 126.3 min; p=0.016), as well as a higher transfusion rate (12.5% vs. 5.6%; p=0.036). There was no statistically significant difference in creatinine levels between the groups. Regarding the stone-free rate, there was a significantly higher proportion of patients in the staged PCNL group (64.9% vs. 43.8%; p=0.012). CONCLUSION: sbPCNL is a safe procedure; however, when compared to staged procedures it has a higher transfusion and lower stone-free rate.

RESUMO INTRODUÇÃO: Paciente com cálculos renais bilaterais e de grande volume são casos desafiadores para os endourologistas. A nefrolitotripsia percutânea bilateral simultânea (NLPbs) é um opção, entretanto esse procedimento pode ser acompanhado de morbidade importante. Uma alternativa é a NLP estagiada, operando um lado de cada vez. Aqui, nós comparamos o impacto da NLPbs e da NLP estagiada nas taxas de complicações e função renal. MÉTODOS: Pacientes que foram submetidos a NLPsb ou NLP stagiada com intervalo de até 6 meses foram pesquisados em nossa base de dados de cálculos renais prospectivamente coletada. Os grupos foram comparados em idade, gênero, índice de massa corpórea (IMC), comorbidades (classificação da Sociedade Americana de Anestesiologia - ASA), tamanho do cálculo, Classificação de Guys, taxa de pacientes livres de cálculos, função renal, perda sanguínea, taxa de transfusão, taxa de complicações e tempo de internação hospitalar. RESULTADOS: Vinte e seis paciente e 52 unidades renais foram incluídas. O tempo operatório médio foi de 134,7 min. Apenas 11.3% dos casos tiveram complicações, sendo todas menores (Clavien ≤ 2). No geral, a taxa de pacientes livres de cálculos foi de 61,5%. Comparando os grupos houve um tempo operatório significativamente maior no grupo NLPbs(172,5 vs. 126,3 min; p=0,016), assim como uma maior taxa de transfusão (12,5% vs. 5,6%; p=0.036). Não houve diferença significante nos níveis de creatinina entre os grupos. Em relação a taxa de doentes livre de cálculos houve uma proporção significativamente maior de pacientes livres de cálculos na NLP estagiada (64,9% vs. 43,8%; p=0,012). CONCLUSÃO: A NLPsb é um procedimento seguro, entretando quando comparada ao procedimento estagiado apresenta uma maior taxa de transfusão e uma menor taxa de pacientes livres de cálculos.

OBJECTIVE@#To compare the outcomes of endoscopic combined ultrasound-guided access (EUGA) with the conventional ultrasound-guided access (UGA) to achieve percutaneous renal access in endoscopic combined intrarenal surgery (ECIRS).@*METHODS@#A retrospective review of 53 patients undergoing ECIRS to treat upper urinary tract calculi between January 2017 and October 2019 was con-ducted. All of the cases were of complex upper urinary tract stones larger than 2 cm in diameter. The com-plex stone situations, such as multiple renal calyces calculi or staghorn calculi necessitated ECIRS. Under general anesthesia, the patients were placed in the galdakao-modified supine valdivia (GMSV) position, thus allowing both antegrade and retrograde accesss. The patients were divided to UGA and EUGA groups according to the protocol of achieving percutaneous renal access. In 28 cases, endoscopic combined ultrasound-guided accesss were obtained. Puncture and dilation were performed under direct flexible ureteroscopic visualization, while percutaneous renal access of 25 cases were performed with the conventional technique employing ultrasound guidance. Demographic and perioperative information, such as stone burden, presence of hydronephrosis and number of calyces involved was compared. Primary outcomes included total operative time, renal access time, repeat puncture, hemoglobin level, perioperative complications, and stone-free rate.@*RESULTS@#No major intra-operative complication was recorded in all the 53 ECRIS. No significant difference was observed between the groups in age and gender. There was no significant difference in body mass index[BMI (29.21±3.14) kg/m2 vs.(28.53±2.56) kg/m2], stone burden (37.68±6.89) mm vs. (35.53±6.52) mm, number of calyces involved 2.72±0.68 vs. 2.86±0.71, presence of hydronephrosis (56.0% vs. 46.4%), total operative time (93.0±12.2) min vs. (96.8±14.2) min, hemoglobin level reduction (6.56±2.16) g/L vs. 97.54±2.64) g/L, stone-free rate (92.0% vs. 92.8%), hospital stay (5.52±0.59) d vs. (5.64±0.62) d, perioperative complication rate (8.0% vs. 7.2%). Two patients in EUGA group experienced perioperative complications (one urinary tract infection and one hematuria) while two patients in UGA group experienced perioperative urinary tract infection. None in both groups received blood transfusion. The patients undergoing EUGA had shorter renal access time [(4.0±0.7) min vs. (6.8±2.6) min, P < 0.01] and less repeat puncture (0 vs. 4 cases, P < 0.05).@*CONCLUSION@#EUGA is an optimal technique to establish percutaneous renal access in ECIRS, which minimizes access time and repeated procedures.

OBJECTIVE@#To discuss the efficacy and safety of simultaneous bilateral endoscopic surgery (SBES) for bilateral upper urinary tract calculi, and to summarize the initial experience.@*METHODS@#Patients diagnosed with bilateral upper urinary tract calculi who underwent SBES in the Department of Urology, Beijing Chao-Yang Hospital from January 2019 to January 2020 were enrolled retrospectively. The demographic and clinical data of the patients were recorded, and the operation status, stone free rate (SFR) and peri-operative complications were analyzed. The primary end point was SFR, and second end point was peri-operative complications.@*RESULTS@#A total of 23 patients underwent SBES, of which SBES was completed in 19 patients (12 males, and 7 females). The mean age was (41.3±12.0) years. Fourteen patients underwent modified supine position surgery and 4 patients in prone split-leg position. There was no statistical difference in the demographic and baseline clinical data of the patients in different positions. One patient underwent right percutaneous nephrolithotomy (PCNL) and left endoscopic combined intra-renal surgery (ECIRS) in the prone split-leg position, while 18 patients received simul-taneous surgery with PCNL and contralateral retrograde intra-renal surgery (RIRS). The mean anesthesia and operation time was (128.7±26.5) min and (70.7±20.3) min, respectively, which was significantly longer in the patients with prone split-leg position than in the patients with modified supine position, anesthesia time in the patients with prone split-leg position and modified supine position: (148.4±20.4) min vs. (121.6±25.3) min, respectively, t=-2.121, P=0.049, while the operation time in the patients with prone split-leg position and modified supine position: (86.4±21.1) min vs. (65.1±17.4) min, respectively, t=-2.222, P=0.040. There was no significant difference between the two groups in indwelling of nephrostomy [prone split-leg position and modified supine position: (2.6±0.9) d vs. (2.1±1.0) d, respectively; t=-0.880, P=0.391] and the length of hospital stay [prone split-leg position and modified supine position: (6.0±2.7) d vs. (5.2±1.8) d, respectively; t=-0.731, P=0.475]. One month after the operation, the SFR was 78.9%, and 3 patients had minor peri-operative complications (Clavien-Dindo grades Ⅰ/Ⅱ) without any serious complications (Clavien-Dindo grades Ⅲ/Ⅳ/Ⅴ).@*CONCLUSION@#The simultaneous bilateral endoscopic surgery would decrease the operation time and anesthesia exposure under the premise of ensuring the SFR, which is helpful to reduce the risk of peri-operative complications, especially to the patients who can not tolerate the second-stage or long-time operation.

OBJECTIVE@#To evaluate the effectiveness of super-selective renal artery embolization in treatment of post-percutaneous nephrolithotomy bleeding, and to analyse the causes of failure embolization.@*METHODS@#In the study, 65 post-percutaneous nephrolithotomy patients with severe renal bleeding and hemodynamic instability were treated by super-selective renal artery embolization. First of all, we performed selective renal arteriography. After clarifying the location of the bleeding, superselective intubation of the injured vessel with a microcatheter was carried out. Then the injured vessel was embolized with Tornado micro-coil. When complete embolization was not achieved with micro-coil, a small amount of gelatin sponge particles were added. If there was no positive finding of the beginning selective renal arteriography, the following measures could be taken to prevent missing lesions: (1) Abdominal aorta angiography was performed to determine whether there were anatomical variations, such as accessory renal arteries or multiple renal arteries; (2) Ultra-selective intubation angiography next to the nephrostomy tube path was performed; (3) Renal arteriography was repeated; (4) Renal arteriography after removing the nephrostomy tube while retaining the puncture channel. We evaluated the different angiographic findings and analysed the causes of embolization failure.@*RESULTS@#Bleeding was successfully controled in 60 patients (62 kidneys) whose renal arteriography was postive. Positive findings included: pseudoaneurysm formation, patchy contrast extravasation, pseudoaneurysm combined with arteriovenous fistula, contrast agent entering the collection system, extravascular perinephric leakage of contrast. After first embolization, bleeding was controled in 53 patients (55 kidneys). The success rate after the first and second embolization was 88.7% and 96.7% respectively. The second session was required because of failure to demonstrate bleeding arteries during the first session (4 patients, 57.1%) and recurrent hemorrhage of the embolized injured arteries (2 patients, 28.6%). In 5 patients with no positive findings, after conservative treatment, hematuria disappeared. All the patients were followed up for 3, 6, and 12 months after embolization, and no hematuria occurred again, and no sustained and serious renal insufficiency.@*CONCLUSION@#Super-selective renal artery embolization is an effective treatment for post percutaneous nephrolithotomy bleeding. The main cause of failure is omitting of injured arteries during renal arteriography. Renal artery branch injury has various manifestations. Attention should paid to the anatomical variation of the renal artery, and patient and meticulous superselective intubation angiography is the key to avoiding missing the lesion and improving the success rate of embolization.

ABSTRACT In complicated urinary tract infection with ureteral calculi, urinary diversion is inevitable. So, stenting or percutaneous drainage can be an option. In hemodynamically unstable patients, percutaneous drainage is superior to ureteral stenting (1). Once acute infection is controlled, definite treatment of the stone is necessary. According to a guideline, semirigid ureteroscopy is recommended for lower and mid - ureter stone and flexible ureteroscopy for upper ureter stone (2). Semi - rigid ureteroscopy can migrate stone to kidney, especially in upper ureter stone, lowering stone free rate (3). Not only flexible ureteroscopy creates additional costs but also is barely available in developing countries (4, 5). So, the authors would like to introduce anterograde irrigation - assisted ureteroscopic lithotripsy in patients with percutaneous nephrostomy. Retrograde irrigation was connected and flowed minimally enough to secure visual field. Once stone is noted, another saline irrigation, which is placed above 40 cm over the patient is connected to nephrostomy. Retrograde irrigation is disconnected from ureteroscope and the previous connected channel on ureteroscope is opened. Actual pressure detected by barometer from the opened channel of ureteroscope is usually about 30 cmH2 O while anterograde irrigation is administered in maximal flow, which means fully opened anterograde irrigation is not hazardous to kidney. There was no complication in 17 patients submitted to this method. Video shows advantages of our practice: clear visual field; reduced risk of stone migration into kidney; induced spontaneous passage of fragments without using instrumentation; and decreased operation time. In short, most of surgeons, even unexperienced, can perform an excellent procedure with less time consuming using our method.

Objective: to evaluate the impact on the quality of life as well as anxiety and pain in patients with nephrostomy tubes. Method: this is a longitudinal descriptive study performed on a sample of n=150 patients. To evaluate the quality of life, the EuroQol-5D questionnaire was used; anxiety was quantified by the Beck Anxiety Inventory; to study pain, a visual analogue scale was employed. Results: statistically significant differences were found in the quality of life, with its worsening (r = 0.51; p <0.01) when evaluated at the first tube replacement. Patients presented mild to moderate anxiety before the procedure, which was reduced at the first tube replacement, although this difference was not significant (r = 0.028, p = 0.393). Finally, the degree of pain was also significantly reduced (r = 0.13, p<0.01) after six weeks. As for gender, women presented the worst values ​​in the three variables studied (worse quality of life and greater anxiety and pain). Conclusions: nephrostomy tubes have a negative impact on the patient's quality of life. During the time they live with these tubes, patients have mild to moderate pain and anxiety.

Para valorar la calidad de vida se empleó el cuestionario EuroQol-5D; la ansiedad fue cuantificada mediante el Inventario de Ansiedad de Beck; para estudiar el dolor se empleó una escala visual analógica. Resultados: encontramos diferencias estadísticamente significativas en la calidad de vida, produciéndose su empeoramiento (r=0.51; p<0.01) cuando fue valorada en el primer cambio de sonda. Los pacientes presentaron una ansiedad leve a moderada previa al procedimiento, que se vio reducida en el primer cambio de sonda, si bien esta diferencia no resultó significativa (r=0.028; p=0.393). Por último, el grado de dolor también se vio disminuido de forma significativa (r=0.13; p<0.01) al cabo de seis semanas. Por sexos, las mujeres presentaron peores valores en las tres variables estudiadas (peor calidad de vida, y mayor ansiedad y dolor). Conclusiones: las sondas de nefrostomía suponen un impacto negativo en la calidad de vida del paciente. Durante el tiempo que conviven con dichas sondas, los pacientes presentan dolor y ansiedad leve a moderada.

Neutrophilic leukemoid reaction may occur in many situations, including hemolysis, malignancy, infection, and exposure to certain toxins. It usually shows morphological overlap with chronic myeloid leukemia in which promyelocytes are not majorly associated. Here, we present a case of promyelocytic leukemoid reaction in a patient with sepsis. A 28-year-old man was admitted for renal stone removal. After percutaneous nephrolithotomy, his condition deteriorated with fever (37.8℃), tachycardia (130/min), acute renal failure, pleural effusion, and pulmonary edema. Complete blood count indicated a white blood cell count of 73.39×10⁹/L including 82% promyelocytes, hemoglobin 8.9 g/dL, and platelet count of 85×10⁹/L. A bone marrow aspirate showed that promyelocytes accounted for 73.8% of all nucleated cells. Following bone marrow examination, treatment with all-trans retinoic acid (ATRA) was started immediately. Reverse transcription polymerase chain reaction (RT-PCR) study revealed the absence of PML-RARA (promyelocytic leukemia-retinoic acid receptor alpha) and other RARA (retinoic acid receptor alpha) rearrangements. Once the chromosome analysis of bone marrow cells demonstrated the normal karyotype, ATRA was discontinued.

Ceftriaxone is commonly used for the treatment of bacterial infection. But it may precipitate in bile causing biliary sludge, pseudolithiasis and gallstone especially in children. We report a case of ceftriaxone-induced acute pancreatitis in an old woman. An 83-year-old woman was admitted for treatment of renal stone. She had received intravenous ceftriaxone for 11 days. After percutaneous nephrolithotomy, she was discharged. After 12 days, she visited the emergency department due to epigastric pain. Laboratory finding was suggestive of gallstone pancreatitis and abdominal computed tomography revealed gallbladder stone, which was absent previously. After conservative care, she received cholecystectomy and discharged without sequelae.

Percutaneous renal puncture device has very important clinical value. Qualified percutaneous renal puncture device is one of the important ways to evaluate its safety and efficacy, and it is also an important prerequisite for the device to be marketed in China. When manufactuers test the product, the selection of representative products is suggested from the aspects of performance parameter, structure, material and production process.
