Strictures of the male urethra: how to perform and evaluate radiourethrography and sonourethrography to avoid mistakes = [Zožitev moške sečnice: pravilna izvedba in vrednotenje radiografske in ultrazvočne uretrografije, da se izognemo napakam] by Darja Babnik-Peskar( )

1 edition published in 2000 in English and held by 2 WorldCat member libraries worldwide

Introduction. Precise evaluation of the uretheral stricture localisation, length, depth and quality of wall changes are necessary for the selection of the optimal treatment to prevent recurrences. Decision for urethral dilatation, internal urethrotomy or open surgery depends on urethroscopic, radiourethrographic-RUG, and recently, according to MC Annich, also sonourethrographic-SUG results. SUG adds information about the depth and density of spongiofibrosis. Previously published findings of RUG length underestimation, compared to SUG and endoscopy, were responsible for inappropriate treatment and recurrences. In our article, we evaluate SUG as a new imaging method in the diagnosis of uretheral strictures and treatment planning, and describe both imaging methods together with usual pitfalls in performance or interpretation, possible reason for incorrect length measurements, and RUG length underestimation. Patients and methods. In the period of 20 months, we evaluated SUG compared to RUG and endoscopy in 51/130 males with suspected urethral strictures. Results. Compared to RUG, sonographywas correct in 92% radiographycally detected strictures. Length measurements by sonography were 22% shorter than radiographic lengths, which could be explained by radiographic magnification, as it was proved with wire measure placed on penis. Considering radiographic magnification, we did not find important differences in any measurement. Opposite to previously published RUG results compared to endoscopy and SUG, radiographic length underestimation was not found. Conclusions. The combination of both imaging methods provides optimal information about urethral stricture anatomy. We conclude that published radiographic length underestimation could be only a misinterpretation. (Abstract truncated at 2000 characters)
Ultrasonographic diagnnosis of obstructive ileus in a patient with Meckel's diverticulum = Ultrazvočna diagnostika obstruktivnega ileusa pri bolniku z Meckelovim divertiklom by Alenka Višnar-Perovič( )

1 edition published in 1999 in English and held by 2 WorldCat member libraries worldwide

Uvod. Kljub uporabi modernih slikovnih tehnik, zanesljiva preoperativna ocena Meckelovega divertikla in z njim povezanih komplikacij te redke prirojene anomalije prebavnega trakta mnogokrat ni mogoča. Predstavitev. Predstavljmo primer 25 letnega moškega, pri katerem se je pojavila nenadna bolečina v spodnjem abdomnu desno. Klinično je bil predel občutljiv na palpacijo, ki je pokazala elastično, valjasto strukturo globoko v trebuhu. Blumbergov znak je bil pozitiven, laboratorijske vrednosti pa v mejah normale. Ultrazvok abdomna je ileocekalno pokazal tekočinsko kolekcijo z gosto vsebino, sumljivo za Meckelov divertikel ali duplikacijsko cisto in ileus ozkega črevesa proksimalno od opisane strukture. Nativni rentgenogram stoje je potrdil prisotnost obstrukcijskega ileusa v distalnem delu ozkega črevesa. Kirurški poseg je odkril ileus in kompresijo distalnega dela ozkega črevesa zaradi prisotnosti edematoznega Meckelovega divertikla. Zaključek. Glede na pogosto uporabo ultrazvoka pri oceni akutnega abdomna, bi lahko racionalizirali diagnostični postopek in skrajšali čas do kirurške intervencije, če bi možne zaplete Meckelovega divertikla upoštevali v diferencialni diagnozi
Adhezijski ileus = Adhesions and intestinal obstruction by Marko Sever( )

1 edition published in 1997 in Slovenian and held by 2 WorldCat member libraries worldwide

Background. The authors pointed out the most frequent diseases and other factors which produce development of adhesions and ileus. Besides history of ilness and clinical features, x ray of abdomen, and US are important. Methods and results. In the period from 1991 to 1994 there were 30 patients operated due to adhesional intestinal obstruction. 10 pts had adhesiolysis and segmental resection of small howel. 10 pts (33.3%) were operated earlier due to adhesions. Conclusions. Proper operative techique, selection of suture material and avoidance of factors causing adhesions can prevent many intestinal obstructions
Clinical importance of portal venous gas detected by abdominal sonography : a report of two cases = Klinični pomen odkritja plina v portalnih venah jeter pri ultrazvočnem pregledu trebuha : prikaz dveh primerov by Primož Gregorič( )

1 edition published in 2004 in English and held by 2 WorldCat member libraries worldwide

Izhodišča. Dokaz plina v veni porte je ponavadi znak resnega obolenja v trebuhu in pomeni slabo prognozo. Z napredkom ultrazvočne diagnostike v zadnjih letih odkrijemo zrak v portalni veni tudi kot prehoden pojav brez kliničnih posledic in sicer pri topi poškodbi trebuha in nekaterih diagnostičnih in terapevtskih postopkih. Prikaz primerov. Predstavljamo dva bolnika. Obema smo pri ultrazvočni preiskavi trebuha odkrili znake plina v portalnih venah, potek bolezni pa je bil diametralno nasproten. Prvi bolnik jebil star 70 let. Utrpel je infarkt mezenterija, čigar posledica je bil plin v portalnih venah. Umrl je nekaj ur po prihodu v bolnišnico. Drugi bolnik je bil star 26 let. Poškodovan je bil kot voznik v prometni nesreči. Med hospitalizacijo je bil klinično stabilen in ni potreboval invazivnega zdravljenja. Ugotovili smo, da se je pojavil plin v portalni veni prehodno zaradi tope poškodbe trebuha. Zaključki. Ultrazvočna preiskava trebuha z uporabo Dopplerja je občutljiva in specifična metoda za dokaz plina v portalnih venah. Z ultrazvočno preiskavo lahko tudi odkrijemo obolenje v trebuhu, ki je vzrok za ta pojav in skrajšamo čas do potrebnega zdravljenja. Če z ultrazvočno preiskavo ne odkrijemo jasnega vzroka za plin v portalnih venah, se moramo o nadaljnih, potencialno nevarnih diagnostičnih in terapevtskih postopkih odločati glede na klinično sliko, ker je pojav plina v portalnih venah lahko tudi prehodnega značaja
Sonographycally guided hydrostatic reduction of childhood intussusception = Dezinvaginacija s hidrokolonsonografijo pri otroku by Dubravka Vidmar( )

1 edition published in 2004 in English and held by 2 WorldCat member libraries worldwide

Background. Intussusception is the most common cause of bowel obstruction in children under two years of age. The proximal part of the bowel and its mesentery (the intussusceptum) enter within that part immediately beneath it (the intussuscipiens). Being pulled by peristalsis the mesenterial vessels getcompressed which result in ishaemia of the bowel wall. Most intussusceptions are ileocolic. The diagnosis can be confirmed by a contrast enema or ultrasound. Sonography demonstrates a so-called target-within-a-target patfern (in cross-section) with thickened edematous bowel wall with or without vascularisation and prestenotic dilatation with increased peristalsis. Therapeutic reduction can be attempted by a contrast enema (following diagnostic procedure) or by air, both under fluoroscopic monitoring, or by normal saline under sonographic guidance. Patients and methods. We detected sonographically intussusception in three girls of 15, 16 and 18 months having typical clinical signs. We continued with hydrostatic reduction under the sonographic guidance. The reduction was attempted with a saline enema on body-temperature, introduced by the equipment for contrast enema. The bottle o f normal saline was hung up 1 m over the examination desk. We needed few liters of saline to replace lost liquids due to the incomplete occlusion of rectum. Meanwhile we monitored the moving of the intussusceptum back into the proximal direction. Criteria for a succesful reduction were the disappearance of the intussusceptum and the passage of fluid through the ileocecal valve. Results. Success was proven in all three girls. No complications occured and the pain relieved immediately after the procedure. There were no signs of intussusception on sonography after 2 and 12hours. We saw a slightly edematous wall of ileocecal valve and terminal ileum. Due to their exellent clinical conditions they were discharged from hospital after a second sonography.

Ultrazvočna diagnostika žočnika in žolčevodov = Ultrasound diagnostics of the gallbladder and the biliary tree by Alenka Višnar-Perovič( )

1 edition published in 2003 in Slovenian and held by 1 WorldCat member library worldwide

Tecnological advances, increased experience and the wide availability of the state of the art machines made ultrasound diagnostics an indispensable tool inthe depiction of almost any kind of condition affecting the gallbladder and the bile ducts. Ultrasonography now plays a broader role not only in the diagnosis but also in the treatment of numerous diseases as an adjunct in the interventional radiology department. It is not only the bedside procedure of the highest flexibility and unlimited follow ups, it is now an evolving technique that extends to the intraductal, endoscopic and intraoperative fields. Ultrasonography has been reported to be very specific in biliary investigations with a liitle lower sensitivity, is effective and low cost investigation
Radiofrekvenčna ablacija primarnih in sekundarnih tumorjev v jetrih = Radiofrequency thermal ablation of the primary and secondary liver tumors( )

1 edition published in 2004 in Slovenian and held by 1 WorldCat member library worldwide

Radiofreqency ablation (RFA) is a local ablative method for treatment of unresectable liver metastases and hepatocellular carcinoma. Patients treated are not suitable for surgical resection due to tumor location or advanced liver disease or they do not want to be operated. RFA is often used as adjuvattherapy with surgical resection. First RFA in Slovenia was performed inJuly 2001. Until March 2004 16 patients were treated, 6 due to HCC, 9 due tometastases of the colorectal carcinoma and one due to liver metastases of carcinoid. RFA is a safe method for treatment liver malignant tumors

Transabdominalni in transperinealni ultrazvočni pregled pri karcinomu prostate = Transabdominal and transperineal ultrasonographic evaluation of prostatic carcinoma by Alenka Višnar-Perovič( )

1 edition published in 1995 in Slovenian and held by 1 WorldCat member library worldwide

Basic problems of diagnostic evaluation of prostatic carcinoma are presented. Diagnostic limitations of the transabdominal and transperineal ultrasound and it's role in TNM classification are underscored. Both approaches are complementary diagnostic procedures, and are only able to help in the differentiation of the advanced disease. transabdominal and transperineal ultrasound is not a part of an early diagnostics or screening for the prostatic carcinoma

Torzija moda - diagnostika z ultrazvočno preiskavo po doplerju - prikaz primera = Testicular torsion - diagnosis by color duplex sonography - a case report by Dubravka Vidmar( )

1 edition published in 2003 in Slovenian and held by 1 WorldCat member library worldwide

Introduction. Testicular torsion is a true surgical emergency due to occlusionof the efferent and/or afferent blood vesssels with consequent ishemia following within the next four hours. This condition requires emergencyoperation and can be diagnosed by color duplex sonography which excludes other causes of acute scrotum: inflammation, traumatic testicular rupture and some other rare conditions, which usually do not necessitate surgery. Patient and method. A 29-year old man with a history of sudden and severe right side scrotal pain was admitted to the urology department. After athree day's treatement for orchoepididymitis the condition didn't improve so an US examination was performed. Results. The B-mode image showed an enlarged hypoechogenic and nonhomogeneous right testis. Golor duplex sonography demonstrated a complete absenee of venous and arterial blood flow. The left testis was normaf in the B-mode image and had normal perfusion as well. The diagnosis of torsion was confirmed operatively. Semicastration was performed because testicular viability was eompletely lost. Conclusion. Color duplex sonography is a rapid and effective method to confirm or exclude test-ticular torsion as a cause of acute scrotum. It improves reliability of decision fof prompt surgical correction and prevents semicastration
Ultrazvočna diagnostika pri bolniku z rakom sečnega mehurja = Ultrasound examination in diagnostics of urinary bladder carcinioma by Alenka Višnar-Perovič( )

1 edition published in 1997 in Slovenian and held by 1 WorldCat member library worldwide

Basic problems of the diagnostic evaluation of urinary carcinoma are presented. Benefits and limitations of transabdominal, transperineal and transurethral ultrasound examination for screening, diagnosis and staging and it's role in TNM classification are discussed. All approaches are complementary diagnostic procedures. Sonography is a sensitive and noninvasivemethod for detection of urinary bladder abnormalities. It should bethe first screening method in patients with macro- or microhematuria. It is possible to detect tumors as small as 2-3 mm. In experienced hands, noninvasive suprapubic sonography gives as good results as invasive intravesical ultrasound and CT for staging of urinary bladder tumours. CT sholuld be used in questionable cases, patients with incontinence and obese patients
