Background: Prolonged urinary leakage after nephrostomy tube removal leads to increased morbidity of PCNL and increased hospitalization. Objective: To evaluate factors affecting post nephrostomy removal urinary leakage after percutaneous nephrolithotomy. Patients and Methods: One hundred eight (108) patients older than 18 years who underwent PCNL were studied prospectively. The reasons that can affect urinary leakage postoperatively were divided into 4 categories according to individual factors including age, gender, and body mass index; Renal factors; including, previous operation, history of ESWL, parenchymal cortical thickness, and grades of hydronephrosis; stone factor (stone burden); and surgical factors including the number of tracts, presence of double J stent, nephrostomy tube diameter and stay duration. These data were compared for postoperative urine leak. Results: Urinary leakage was revealed in 76 of 108 patients (70.3%). There was no statistically significant relationship between individual factors and urinary leakage (P >0.05). Among renal factors, just parenchymal cortical thickness and grade of hydronephrosis were strongly related to the urinary leakage (P <0.001). The renal stone burden did not affect urinary leakage (P >0.05). Among surgical factors, placing of ureteral double-J stent highly minimized the incidence of urinary leakage (P<0.001), and the urinary leakage significantly correlated with the increased diameter of the nephrostomy tube and staying duration (P<0.05). Conclusion: After PCNL surgery, some factors show to influence post-PCNL urinary leakage. however most of the urinary leakage was treated conservatively, but it increases morbidity and hospitalization.

Abstract Purpose: To evaluate the aspects affecting transfusion following percutaneous nephrolithotomy (PCNL).Background: From 2016 to 2019, 665 patients underwent PCNL for removal of renal calculi in our center. Complications, including hemorrhages, have been reported. Twenty-three patients (3.5%) have received a blood transfusion and twelve (1.9%) were treated by hyper-selective embolization. We focus on the influencing factors related to postoperative blood transfusion. The factors analyzed were (age, sex, hypertension, diabetes, serum creatinine level, preoperative hemoglobin, and use of anticoagulants or antiplatelet medications); renal and stone factors (previous surgery, abnormal anatomy, stone side, stone burden, stone type); and surgical features: (access number, the calyx of puncture and stone-free rate). These data were analyzed for the presence of bleeding.Results: Among individual factors, preoperative hemoglobin level (P<0.001), and urinary infection (P<0.001) were significantly correlated with blood transfusion. Among renal and stone factors, only previous history of open surgery was significantly correlated with blood transfusion (P<0.05). Stone type or stone burden does not correlate with transfusion. There was also no statistically significant correlation between surgical features and bleeding, and a lower stone-free rate reported for transfusion group.Conclusion: The obtained results demonstrated that PCNL is a safer surgery in a high volume center, but anemic conditions, infections and history of open surgery will significantly increase transfusion rate following PCNL.

Objectives: Percutaneous nephrolithotomy on staghorn calculi is challenging for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Methods: We collected data from medical record between January 2000 and December 2015. A total of 345 primary percutaneous nephrolithotomy procedures were performed for patients with staghorn calculi. This study included both and made no distinction between partial and complete staghorn calculi. Stone-free is defined as the absence of residual stones after undergoing percutaneous nephrolithotomy for the first time. Significant factors from univariate analysis that correlated with stone-free rate after primary percutaneous nephrolithotomy of staghorn stone were further analyzed using multivariate regression analysis. Results: The mean patient age was 52.23±10.38 years. The stone-free rate of percutaneous nephrolithotomy monotherapy was 62.6%. The mean operating time was 79.55±34.46 minutes. The mean length of stay in hospital was 4.29±3.00 days. Using the chi-square test, history of ipsilateral open renal stone surgery (p = 0.01), stone burden (p = < 0.001), and type of anesthesia (p = 0.04) had a significant impact on the stone-free. From multivariate analysis, the history of ipsilateral open renal stone surgery [OR 0.48; 95% CI 0.28-0.81; p 0.01] and the stone burden [OR 0.28; 95% CI 0.18-0.45; p 0.00] were significant independent risk factors for stone-free.

Transvaginal Oocyte Retrieval

We report a case of ureteral injury with delayed hematuria after transvaginal oocyte retrieval. A 28-year-old infertile patient with a history of previous laparoscopic resection of endometriotic nodes of both sacrouterine ligaments presented with abdominal pain one day after oocyte retrieval. Four days after oocyte retrieval, she presented with massive hematuria that reappeared 6 days after oocyte retrieval. Monopolar coagulation with wire electrode and insertion of a double-J-stent was performed during operative cystoscopy. The patient recovered completely after transfusion and had no signs of renal impairment after ureteric stent removal. This is the first report of ureteral injury after oocyte retrieval presenting itself with delayed massive hematuria and no signs of renal dysfunction or urinary leakage into retroperitoneal space.

The pharmaceutical industry has faced several marked challenges in order to bring new chemical entities (NCEs) into the market over the past few decades. Various novel drug delivery approaches have been used as a part of life cycle management from which Osmotic drug delivery systems look the most promising one. After discussing the history of osmotic pump development, this article looks at the principles, advantages and disadvantages of osmotic drug delivery systems. Then, the basic components of osmotic pump and factors affecting the design of oral osmotic drug delivery systems are discussed in detail. In the later part of the manuscript, various types of osmotic pumps available in the market and evaluation methods for osmotic drug delivery systems are discussed in detail.
