This study investigated whether a high-fructose (HFr) diet changes the morphology of seminiferous tubules (ST) in rats and resveratrol (RES) has a possible restoring effect in this sense. Fructose (30%; w/v) was administered to rats alone or together with RES (50 mg/L) in drinking water for 8 weeks. In the HFr group, destruction of the germinal epithelium led to the detection of immature germ cells in the lumen. HFr diet gave rise to a decrease in the ST diameters (p < 0.05), Johnsen's tubular biopsy score values (p < 0.001), and an increase in the apoptotic index (p < 0.05). Ultrastructurally, HFr feeding increased lipid accumulation (p < 0.01), mitochondrial damage, and acrosomal abnormalities in spermatogenic cells. Treatment of HFr -fed rats with RES improved the reduced ST diameters and overall general histological and ultrastructural abnormalities of the STs, but did not change the increased apoptotic index.
Bladder stones heavier than 100 g are defined as giant bladder stones. Bladder stones occur rarely in women compared to men. Bladder stones in women generally occur secondary to passage of suture material through the bladder following pelvic or gynecologic surgery. The disease is frequently manifested clinically with hematuria, recurrent urinary tract infection or urine retention. In this article, a 31-year-old woman who presented with nonspecific urinary tract symptoms and was found to have a giant bladder stone with a weight of 280 g as a result of the studies performed is presented. (JAREM 2014; 4: 132-4) Key Words: Young woman,giant bladder stone, sistolithotomy ÖZET Ağırlığı 100 gr.`ın üzerindeki mesane taşları dev mesane taşı olarak tanımlanır. Erkeklere nazaran kadınlarda mesane taşları nadir olarak görülmektedir. Genellikle kadınlarda mesane taşları pelvik ya da jinekolojik cerrahi sonrası sütür materyalinin mesaneden geçmesine ikincil oluşmaktadır. Hastalar sık-lıkla hematüri, tekrarlayan idrar yolu enfeksiyonu veya idrar retansiyonu seklinde klinik bulgu verir. Bu yazıda, özgün olmayan üriner sistem belirtileri ile başvuran ve yapılan tetkikleri sonucu 280 gr ağırlığındaki dev mesane taşı tespit edilen 31 yaşındaki bir kadın hasta sunulmuştur.

PurposeTo compare urethral stricture rates in comorbid patients undergoing plasmakinetic transurethral resection of the prostate (PK-TURP) and monopolar transurethral resection of the prostate (M-TURP) for benign prostatic hyperplasia.MethodsThe data of 317 patients with comorbidities undergoing either PK-TURP or M-TURP from September 2008 to December 2012 were retrospectively evaluated. Preoperative and postoperative 12-month International Prostate Symptom Score, maximal flow rate, postoperative International Index of Erectile Function scores, and urethral stricture rates were evaluated.ResultsA total of 154 patients underwent M-TURP and 163 patients underwent PK-TURP. Urethral stricture rates were 6/154 in the M-TURP treatment arm and 17/163 in the PK-TURP treatment arm (P=0.000). In the presence of hypertension and/or coronary artery disease and/or diabetes mellitus, the risk of urethral stricture complication was significantly higher in the PK-TURP group than in the M-TURP group (P=0.000).ConclusionsThe risk of urethral stricture increases with PK-TURP in elderly patients with a large prostate and concomitant hypertension and/or coronary artery disease and/or diabetes mellitus. Therefore, PK-TURP should be performed cautiously in this group of benign prostatic hyperplasia patients.
The presence of spina bifida occulta significantly affects the response to medical treatment in patients with PMNE. Thus, verifying spina bifida occulta status in PMNE can facilitate prognostic predictions about the response to medical treatment.
This study revealed a metabolic tendency to hypercalciuria in calcium oxalate stone patients, predominantly in those with recurrent calcium oxalate urolithiasis. Urinary oxalate excretion was found to be higher in recurrent urolithiasis in comparison to the first episode of calcium oxalate urolithiasis and urinary citrate excretion lower in recurrent urolithiasis.
ÖZETMesanede en sık rastlanan tümörler ürotelyal karsinomlar olmakla birlikte mesane kanserlerinin %10-20' sinde farklı diferansiyasyon gösteren tümörlerde bulunabilir. Bunlardan biride sarkomatoid ve lenfoepitelyoma benzeri diferansiyasyon gösteren ürotelyal karsinomdur. Daha çok erkeklerde ve ileri yaşta görülür. Tanı anında genelde ileri evredirler. Agresif neoplaziler olup sürvileri kötüdür. Literatürde çeşitli tedavi modaliteleri belirlenmiş olup kesin bir standart yoktur. Bu yazıda ender rastlanan sarkomatoid ve lenfoepitelyoma benzeri diferansiyasyon gösteren ürotelyal mesane karsinomu vakasına uyguladığımız parsiyel sistektominin sonucu literatür eşliğinde tartışılmıştır. (JAREM 2014; 1: 35-7) Anahtar Sözcükler: Mesane, sarkomatoid, ürotelyal karsinom, parsiyel sistektomi ABSTRACT Urothelial carcinomas are the most common tumor types in urinary bladder; however, there may exist different differentiations in 10-20% of bladder cancer, one of which is urothelial carcinoma that has sarcomatoid-and/or lymphoepithelioma-like differentiation. It is usually seen in males in older age and diagnosed during later stages. They are aggressive malignancies and have low survival. Although there are various treatment models determined in the literature, no certain standard is identified. In this study, we report a case of sarcomatoid-and lymphoepithelioma-like differentiated urothelial carcinoma of the urinary bladder that was treated by partial cystectomy and its results in light of the literature. (JAREM 2014; 1: 35-7) Key Words: Urinary bladder, sarcomatoid, urothelial carcinoma, partial cystectomy GİRİŞ Ürolojik kanserler içinde prostat kanserinden sonra ikinci sırada yer alan mesane tümörleri, erkeklerde görülen kanserler içinde dördüncü, kadınlarda ise sekizinci sırada yer almaktadır (1). Mesanede en sık %90-95 oranla ürotelyal hücreli kanser görülür, tanı sırasında yaklaşık %10-20'sinde farklı diferansiyasyon gösteren tü-mörlerde görülebilir (2). Sarkomatoid diferansiyasyon Torenbeek ve ark. (3) 4191 mesane kanserli hastayı inceledikleri çalışmasında %0.31 olarak bildirilmektedir (3).

OLGU SUNUMUElli altı yaşında erkek hasta pıhtılı makroskopik hematüri şikayet-leri ile kliniğimize başvurdu. Fizik muayenesi, serum biyokimyası ve kan sayımı normaldi. Üriner sistem ultrasonografide (USG) mesane posterior duvarda 50x45x35 mm boyutlarında kitle lezyon tespit edildi ve üst üriner sisteme ait patoloji izlenmedi (Resim 1).Hastaya transüretral rezeksiyon (TUR) planlandı. Sistoskopi önce-si yapılan bimanuel muayenede ele gelen kitle ve fiksasyon yoktu. Mesane arka duvar kubbe bileşkesinde yaklaşık 5 cm çapında papillo-solid tümoral odak izlendi ve rezeksiyon yapıldı (TUR-MT), mesaneden multipl ve prostatik üretradan örnekleme yapıldı.

If the aim of treatment in androgen dependent prostatic adenocarcinoma or benign prostate hypertrophy is the construction of a robust apoptosis, bilateral orchiectomy generates a more powerful apoptosis compared with Leuprolide.
