Mild, selektiv und effizient: Eine neue Methode mit Trimethylzinnhydroxid zur Hydrolyse bestimmter Esterfunktionen vermeidet ungewollte Eliminierungen und Epimerisierungen. Beispielsweise wird der Ester 1 unter milden Bedingungen in die Carbonsäure 2 umgewandelt, wobei die stereochemische Integrität annähernd gewahrt wird. 1,2-DCE=1,2-Dichlorethan.

WCS group showed comparable migration rate and significantly more durable long-term stent patency compared with UCS group for the palliation of GOO in patients with inoperable gastric cancer.

The clinical success of mitomycin C (1) and its associated toxicities and resistance have led to efforts to prepare semisynthetic analogues (i.e., KW-2149 (3), BMS-181174 (4)) that have improved pharmacological profiles. In this study, we report the preparation and evaluation of the novel 7-N-(1'-amino-4',5'-dithian-2'-yl)porfiromycin C(8) cyclized imine (6) and its reference compound, 7-N-(1'-aminocyclohex-2'-yl)porfiromycin C(8) cyclized imine (13). Porfiromycin 6 contains a disulfide unit tha

BACKGROUND: Complicated acute pyelonephritis (APN) is a life-threatening condition that requires immediate intervention. This study examined the characteristics of APN occurring as a complication of ureteral stone. METHODS: We retrospectively reviewed 85 patients diagnosed with APN complicated by ureteral stone between December 2006 and July 2017 at our institution. Patients with concomitant renal stone, multiple ureteral stones, ureteral strictures, ureteral cancer, and urogenital anomalies, in

ABSTRACT: We aimed to evaluate the risk factors of febrile urinary tract infection (UTI) following retrograde intrarenal surgery (RIRS) for treating renal stones.We retrospectively reviewed the data of patients with 10 - 30 mm kidney stones who underwent RIRS from January 2014 to July 2017. Evaluation included age, gender, body mass index, stone size, stone location, and operative time. All surgeries were performed by a single surgeon and ureteral stenting was not done prior surgery. The risk fa

OBJECTIVES: To compare post-nephrectomy renal function between kidney donors and renal cell carcinoma patients, to evaluate trends in recovery, and to identify factors relevant to renal failure. METHODS: Patients who had radical or donor nephrectomy from four different institutions between 2003 and 2012 were reviewed. Propensity score matching was carried out and 79 patients were selected for each group. The estimated glomerular filtration rate was calculated using the Modification of Diet in Re

Laparoscopic retroperitoneal lymph node dissection, especially when performed with the da Vinci Surgical System (Intuitive Surgical), has shown excellent cosmetic results with similar oncologic outcomes to those of open surgery. In this study, we present a case of robot-assisted retroperitoneal lymph node dissection performed in an 18-year-old man who was diagnosed with a stage IIIb mixed germ cell tumor and who was initially treated with radical orchiectomy, followed by chemotherapy. This case

To the Editor: Qvist1 first reported acute idiopathic scrotal edema (AISE) in 1956. No specific cause has been identified. Here, we discuss 2 cases of AISE caused by acute Epstein–Barr viral (EBV) infection. A 13-year-old male and a 6-year-old boy visited our hospital because of penile, scrotal and perineal swelling. Both of them reported no trauma to the perineal area and had never experienced an allergic reaction to any medications. Laboratory tests including urinalysis were normal. Penile and

The prevalence of urinary incontinence in medical welfare facilities in Korea was about 65.3%. However, the management of urinary incontinence was insufficient. Urologists should make further efforts for the proper management of urinary incontinence in elders in these facilities.

Patient age greater than 60 years, Fuhrman grade ≥ 3, and tumor stage ≥ pT2 are independent risk factors of recurrence more than 5 years after surgery in patients with RCC. Therefore, close lifelong follow-up is recommended for patients with these risk factors.

Purpose: The prevalence of urinary incontinence and the usage of incontinence pads by elderly residents in Korean medical welfare facilities were investigated. Methods: From a total of 1,832 facilities, 33 medical welfare facilities in the capital area were randomly selected; all nursing homes were excluded. All data were collected by questionnaires to investigate the residents’ age and sex, the presence or absence of urinary incontinence, incontinence pad usage per month, and management methods

The objectives of this study were to investigate patients treated for scrotal trauma at our institute for the last three decades to describe our experience with an emphasis on the etiologies and ultrasonographic findings in these patients. We reviewed medical records of patients who underwent scrotal ultrasonography for evaluation of testicular trauma at our institutes from 1986 to 2015. Trends regarding the etiology of scrotal trauma were evaluated during each decade. The echo pattern and conto
