Unusual Presentation of Renal Cell Carcinoma: Gluteal Metastasis

Renal cell carcinoma (RCC) has widespread and unpredictable metastatic potential. The most common sites of metastatic RCC are the lungs, lymph nodes, bones, liver, and brain; however the soft tissue metastasis is rare (2,3). Here we report a 76-year-old male patient who had renal cell carcinoma presented with gluteal metastasis. To our knowledge this is the first renal cell cancer case with gluteal metastasis at the initial diagnosis

Fracture With Urethral Injury: Evaluation by Retrograde Urethrogram

Penil fraktür nadir görülen bir durumdur. Penis ereksiyonu esnasında oluşan travma sonucu öncelikle korpus kavernozum rüptürü oluşur ve bu esnada korpus spongiozum ve üretra da etkilenebilir. 35 yaşında erkek hasta cinsel ilişki sırasında oluşan künt travma sonrasında akut penil ağrı, penil şişlik ve hematüri ile acil servise başvurdu. Acil retrograd üretrogram çekiminde verilen opak maddenin penil üretradan kavernoz yapılara ekstravaze olduğu (nadir görülen) izlendi. Penil üretradaki ve kavernöz yapılardaki parsiyel rüptür cerrahi olarak onarıldı. Hastanın post-operatif 3. aydaki takibinde, komplikasyonun olmadığı ve hastanın ereksiyonunun ve işeme fonksiyonunun normal olduğu gözlendi. Üretral yaralanma şüphesi olan penil fraktur olgularında retrograd üretrogram tanı koyduru cudurPenile fracture is a rare condition. It primarily involves the rupture of the corpus cavernosum during erection, which may also affect the corpus spongiosum and urethra. We describe the case of a 35-year-old man who presented with acute penile pain, penile swelling, and a hematuria after a blunt trauma during sexual intercourse. The emergency retrograde urethrogram revealed a rare condition, extravasation of the opaque material from the penile urethra into the cavernous structure. The partial rupture of the corpus cavernosum with urethral disruption was repaired surgically. At the 3-month postoperative follow-up control, no complications were reported by the patient who has had both normal erectile and voiding functions. In cases of penile fracture with suspected urethral injury, retrograde urethrogram can be used for definitive diagnosi

Midline Prostatic Cyst Marsupialization Using Holmium Laser

Many of the prostatic cysts are asymptomatic and only 5% are symptomatic (Hamper et al., 1990; Higashi et al., 1990). These symptoms include pelvic pain, hematospermia, infertility, voiding dysfunction, prostatitis-like syndrome, and painful ejaculation. Treatment of prostatic cysts includes TRUSG guided drainage, endoscopic transurethral resection, and in some cases even open surgery. In the literature, endoscopic interventions use marsupialization of the midline prostatic cyst with transurethral resection (TUR) or transurethral incision with endoscopic urethrotomy (Dik et al., 1996; Terris, 1995). Holmium: YAG laser was employed for the marsupialization of the cyst wall in midline prostatic cyst treatment for the first time in the present study. Symptoms, treatment, and follow-up are presented in this paper

Increased concentration of soluble CD40 ligand in preeclampsia

Preeclampsia has been associated with increased platelet activation detected before disease onset. Platelets are involved in hemostasis and also directly initiate an inflammatory response of the vessel wall. Inappropriate activation of platelets may be involved in pathogenesis in preeclampsia by promoting coagulation and thrombosis, and also as a mediator of inflammation. Platelets may release inflammatory mediators such as soluble CD40 ligand. The plasma level of soluble CD40 ligand was investigated during preeclamptic (n =20) and normal pregnancies (n = 20) to emphasize inflammatory response in preeclampsia. The mean soluble CD40 ligand levels were 1.08 +/- 0.43 ng/mL in patients with preeclampsia and 0.76 +/- 0.24 ng/mL in healthy pregnant women, which was statistically significant (P =. 01). To clarify whether inflammation may cause inappropriate endothelial cell activation or inappropriate endothelial cell activation may start this inflammatory response, future studies are needed in a larger study population

Factors predicting postoperative febrile urinary tract infection following percutaneous nephrolithotomy in prepubertal children

WOS: 000451374800039PubMed ID: 29779995Background Predictive tables and scoring systems can predict stone clearance. However, there is a paucity of evidence regarding the prediction of complications during percutaneous nephrolithotomy (PCNL), particularly in children, which remains under-researched. To our knowledge, no studies have evaluated the risk factors for febrile urinary tract infection (FUTI) after pediatric PCNL. Objectives To assess the predictive factors of FUTI in prepubertal children after PCNL and determine whether any prophylactic cephalosporins are superior for decreasing the FUTI rate. Study design Data from 1157 children who underwent PCNL between 1991 and 2012 were retrieved from the multicenter database of the Turkish Pediatric Urology Society. Children >12 years of age were excluded, leaving 830 children (364 girls, 466 boys). Data were analyzed according to the presence of FUTI and compared between the FUTI and non-FUTI groups. Results Mean age was 6.46 +/- 3.38 years. Twenty-nine (3.5%) children had FUTI which was confirmed by urine culture. FUTI Table Predictive factors for FUTI. occurred more frequently in young children (5.5%) than school-age children (2.4%). In univariate analysis, there were significant differences between the FUTI and non-FUTI groups regarding age, cephalosporin subgroup (first, second and third generation cephalosporin), side of PCNL, staghorn stones, tract size, operative time, postoperative ureteral catheter usage, perioperative complications (SATAVA), and blood transfusion. Multivariate analysis revealed that age, side of PCNL, staghorn stones, tract size, operative time, and blood transfusion were independent predictors of FUTI. Discussion The smaller tract size could cause FUTI with poor fluid drainage that may lead to elevate renal pelvic pressure and trigger bacteremia-causing pyelovenous backflow. Filling the calyx and renal pelvis by a staghorn stone and the resulting obstruction of fluid drainage may elevate intrarenal pelvis pressure. Longer operative time is likely to increase renal pelvic pressure over longer periods, which may account for FUTI after pediatric PCNL. Conclusions Younger age, right-sided PCNL, staghorn stones, mini-PCNL, longer operative time, and blood transfusion are risk factors for FUTI. First-, second-, and third-generation cephalosporins are equally effective for prophylaxis in prepubertal children undergoing PCNL.Scientific Research Projects Coordination Unit of Istanbul UniversityIstanbul University [1030-24135]Bulent Onal was supported by Scientific Research Projects Coordination Unit of Istanbul University.

Factors Affecting Complication Rates of Ureteroscopic Lithotripsy in Children: Results of Multi-Institutional Retrospective Analysis by Pediatric Stone Disease Study Group of Turkish Pediatric Urology Society

WOS: 000293688300097PubMed ID: 21784482Purpose: We evaluated factors affecting complication rates of ureteroscopy for pediatric ureteral calculi. Materials and Methods: We retrospectively evaluated 642 children who underwent ureteroscopy at 16 Turkish centers between 2000 and 2010. Semirigid ureteroscopy was used with various calibers to treat 670 ureteral units in 660 sessions. Complications were evaluated according to the Satava and Clavien classification systems. Univariate and multivariate analyses were done to determine predictive factors affecting complication rates. Results: A total of 367 females and 265 males were studied. Mean +/- SD patient age was 90.2 +/- 51.4 months (range 4 to 204). Mean +/- SD stone size, operative time and postoperative hospital stay were 8.9 +/- 4.7 mm, 45.8 +/- 23.8 minutes and 1.8 +/- 2.8 days, respectively. At a mean +/- SD followup of 13.3 +/- 17.6 months 92.8% of patients were stone-free and efficacy quotient was 90.3%. Complications, which occurred in 8.4% of patients (54 of 642), were intraoperative in 25 (Satava grade I to II in 22), early postoperative in 25 (Clavien grade I to II in 23) and late postoperative in 4 (all grade III). While operative time, age, institutional experience, orifice dilation, stenting and stone burden were statistically significant on univariate analysis, multivariate analysis revealed that operative time was the only statistically significant parameter affecting the complication rate. Conclusions: Semirigid ureteroscopy is effective, with a 90% stone-free rate and efficacy quotient. Most complications are low grade and self-limiting. Our results confirm that prolonged operative time is an independent predictor of complications, and should be considered when choosing and performing the treatment modality
