Abstract

Abstract Aim: We present a case of large-volume ureteral steinstrasse that formed and resolved spontaneously without any medical expulsive therapy (MET) or surgical intervention. Case: A 36-year-old male patient presented with left flank pain. Non-contrast computed tomography revealed high-density calculi obstructing the left upper ureter, with a total stone burden of 4.5 cm, accompanied by grade 3 hydronephrosis. The patient declined the recommended endoscopic surgery. At the 13-month follow-up, multiple stones with a total length of 5.1 cm were observed in the distal ureter. Within two weeks, four stones (8.4, 7.3, 6.6, and 4.7 mm) passed spontaneously; the remaining large stone (24×11 mm), which became impacted in the prostatic urethra, was managed by endoscopic cystolithotripsy. Throughout follow-up, renal function tests remained within normal limits, and no significant loss of renal parenchyma was detected. Conclusions: Large ureteral steinstrasse may pass spontaneously without urological intervention or MET. Keywords: ureteral calculi; steinstrasse; spontaneous passage; hydronephrosis

Özet

Özet Amaç: Herhangi bir medikal ekspulsif tedavi (MET) veya cerrahi girişim uygulanmaksızın kendiliğinden oluşan ve yine kendiliğinden çözülen geniş hacimli bir üreteral taşyolu olgusunu sunuyoruz. Olgu: Otuz altı yaşında erkek hasta sol yan ağrısı şikâyetiyle başvurdu. Kontrastsız bilgisayarlı tomografide sol üst üreteri tıkayan, toplam taş yükü 4,5 cm olan yüksek dansiteli taşlar ve buna eşlik eden grade 3 hidronefroz saptandı. Hasta önerilen endoskopik cerrahiyi kabul etmedi. On üçüncü ay takibinde distal üreterde toplam uzunluğu 5,1 cm olan çok sayıda taş gözlendi. İki hafta içinde dört taş (8,4; 7,3; 6,6 ve 4,7 mm) kendiliğinden düştü; prostatik üretrada impakte hâle gelen geriye kalan büyük taş (24×11 mm) endoskopik sistolitotripsi ile tedavi edildi. Takip süresi boyunca böbrek fonksiyon testleri normal sınırlarda kaldı ve anlamlı bir renal parankim kaybı saptanmadı. Sonuç: Geniş üreteral taşyolu, ürolojik girişim veya MET uygulanmaksızın kendiliğinden düşebilir. Anahtar kelimeler: üreter taşı, taşyolu, spontan pasaj, hidronefroz
